66-629: Since its founding in 1971, Ludwig Cancer Research has committed more than US$ 2.5 billion to cancer research. Ludwig Cancer Research focuses on both basic research and translational research , with specific emphasis on cell biology , genomics , immunology , neuroscience , prevention , cell signaling , stem cells , therapeutics , and tumor biology, as well as clinical trials and the design and development of small molecules with drug-like properties. Its researchers also focus on particular types of malignancy , including brain cancer , breast cancer , colon cancer , and melanoma . Daniel K. Ludwig

132-709: A 22-fold increased risk of cervical cancer. The carcinogenic HPV types in cervical cancer belong to the alphapapillomavirus genus and can be grouped further into HPV clades . The two major carcinogenic HPV clades, alphapapillomavirus-9 (A9) and alphapapillomavirus-7 (A7), contain HPV16 and HPV18 , respectively. These two HPV clades were shown to have different effects on tumour molecular characteristics and patient prognosis, with clade A7 being associated with more aggressive pathways and an inferior prognosis. In 2020, about 604,000 new cases and 342,000 deaths from cervical cancer occurred worldwide. Around 90% of these occurred in

198-643: A biotech that sought to create cancer medicines based on this discovery. The pharmaceutical company Roche purchased the company. Drugs based on these discoveries are now being evaluated for the treatment of many cancers, including breast and lung cancer . Contributions in the field of genomics include the work of Ludwig researchers at Johns Hopkins to sequence the full complement of genes expressed in many cancers, including head and neck, colon, and breast cancers, as well as glioblastoma multiforme (GBM). Ludwig researchers in San Diego significantly advanced studies of

264-428: A group reported that, in frozen blood samples of 57 sexually naive pediatric patients who had vertical or transfusion-acquired HIV infection, 8 (14.0%) of these samples also tested positive for HPV-16. This seems to indicate that it may be possible for HPV to be transmitted via blood transfusion . However, as non-sexual transmission of HPV by other means is not uncommon, this could not be definitively proven. In 2009,

330-407: A group tested Australian Red Cross blood samples from 180 healthy male donors for HPV, and subsequently found DNA of one or more strains of the virus in 15 (8.3%) of the samples. However, it is important to note that detecting the presence of HPV DNA in blood is not the same as detecting the virus itself in blood, and whether or not the virus itself can or does reside in blood in infected individuals

396-564: A problem in the future. In the United States, basic research is funded mainly by the federal government and done mainly at universities and institutes. As government funding has diminished in the 2010s, however, private funding is increasingly important. Applied science focuses on the development of technology and techniques. In contrast, basic science develops scientific knowledge and predictions, principally in natural sciences but also in other empirical sciences, which are used as

462-482: A protein (also called E6) that simultaneously binds to two host cell proteins called p53 and E6-Associated Protein ( E6-AP ). E6AP is an E3 Ubiquitin ligase , an enzyme whose purpose is to tag proteins with a post-translational modification called Ubiquitin. By binding both proteins, E6 induces E6AP to attach a chain of ubiquitin molecules to p53, thereby flagging p53 for proteosomal degradation. Normally, p53 acts to prevent cell growth and promotes cell death in

528-461: A rapid growth of cells on the outer layer of the skin. While cases of warts have been described since the time of ancient Greece, their viral cause was not known until 1907. Skin warts are most common in childhood and typically appear and regress spontaneously over the course of weeks to months. Recurring skin warts are common. All HPVs are believed to be capable of establishing long-term "latent" infections in small numbers of stem cells present in

594-599: A virus. HPV is a group of more than 200 related viruses, which are designated by a number for each virus type. Some HPV types, such as HPV5, may establish infections that persist for the lifetime of the individual without ever manifesting any clinical symptoms. HPV types 1 and 2 can cause common warts in some infected individuals. HPV types 6 and 11 can cause genital warts and laryngeal papillomatosis . Many HPV types are carcinogenic . About twelve HPV types (including types 16, 18, 31, and 45) are called "high-risk" types because persistent infection has been linked to cancer of

660-518: A wide range of HPV types and squamous cell carcinoma of the skin . In such cases, in vitro studies suggest that the E6 protein of the HPV virus may inhibit apoptosis induced by ultraviolet light . Nearly all cases of cervical cancer are associated with HPV infection, with two types, HPV16 and HPV18, present in 70% of cases. In 2012, twelve HPV types were considered carcinogenic for cervical cancer by

726-421: Is among the most common cancers worldwide, causing an estimated 604,000 new cases and 342,000 deaths in 2020. About 90% of these new cases and deaths of cervical cancer occurred in low- and middle-income countries . Roughly 1% of sexually active adults have genital warts. Cases of skin warts have been described since the time of ancient Greece , but it was not until 1907 that they were determined to be caused by

792-676: Is associated with an increasing number of head and neck cancers . This association is independent of tobacco and alcohol use. The local percentage varies widely, from 70% in the United States to 4% in Brazil. Engaging in anal or oral sex with an HPV-infected partner may increase the risk of developing these types of cancers. In the United States, the number of newly diagnosed, HPV-associated head and neck cancers has surpassed that of cervical cancer cases. The rate of such cancers has increased from an estimated 0.8 cases per 100,000 people in 1988 to 4.5 per 100,000 in 2012, and, as of 2021,

858-436: Is believed to be specific to a specific strain of HPV. In addition to genital warts, infection by HPV types 6 and 11 can cause a rare condition known as recurrent laryngeal papillomatosis , in which warts form on the larynx or other areas of the respiratory tract. These warts can recur frequently, may interfere with breathing, and in extremely rare cases can progress to cancer. For these reasons, repeated surgery to remove

924-444: Is beneficial, or who should get an anal Pap smear. HPV is associated with approximately 50% of penile cancers . In the United States, penile cancer accounts for about 0.5% of all cancer cases in men. HPV16 is the most commonly associated type detected. The risk of penile cancer increases 2- to 3-fold for individuals who are infected with HIV as well as HPV. Oral infection with high-risk carcinogenic HPV types (most commonly HPV 16)

990-628: Is caused by the human papillomavirus , a DNA virus from the papillomavirus family. Over 200 types have been described. An individual can become infected with more than one type of HPV, and the disease is only known to affect humans. More than 40 types may be spread through sexual contact and infect the anus and genitals . Risk factors for persistent infection by sexually transmitted types include early age of first sexual intercourse , multiple sexual partners, smoking, and poor immune function . These types are typically spread by sustained direct skin-to-skin contact, with vaginal and anal sex being

1056-445: Is less common for female genital HPV infection. Fingers-genital contact is a possible way of transmission but unlikely to be a significant source. Though it has traditionally been assumed that HPV is not transmissible via blood – as it is thought to only infect cutaneous and mucosal tissues – recent studies have called this notion into question. Historically, HPV DNA has been detected in the blood of cervical cancer patients. In 2005,

1122-482: The International Agency for Research on Cancer : 16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, and 59. One study found that 74% of squamous cell carcinomas and 78% of adenocarcinomas tested positive for HPV types 16 or 18. Persistent HPV infection increases the risk for developing cervical carcinoma. Individuals who have an increased incidence of these types of infection are women with HIV/AIDS, who are at

1188-726: The National Academy of Sciences (US): Academy of Medical Sciences (UK): Branches and laboratories Ludwig Centers Basic research Basic research , also called pure research , fundamental research , basic science , or pure science , is a type of scientific research with the aim of improving scientific theories for better understanding and prediction of natural or other phenomena. In contrast, applied research uses scientific theories to develop technology or techniques, which can be used to intervene and alter natural or other phenomena. Though often driven simply by curiosity , basic research often fuels

1254-536: The developing world . Most HPV infections of the cervix are cleared rapidly by the immune system and do not progress to cervical cancer (see below the Clearance subsection in Virology ). Because the process of transforming normal cervical cells into cancerous ones is slow, cancer occurs in people having been infected with HPV for a long time, usually over a decade or more (persistent infection). Furthermore, both

1320-601: The epigenome , leading such efforts as the NIH's Roadmap Epigenomics Project. The Ludwig Cancer Research board of directors helps oversee both the Ludwig Institute for Cancer Research and the Ludwig Fund. Although each of these entities has its own board, the boards comprise the same individuals. The current chairman of the board is Edward McDermott, Jr., former President and CEO of LICR. The executive staff manages

1386-561: The exhaled breath condensate (EBC), bronchial brushing and neoplastic lung tissue of cases, and found a presence of an HPV infection in 16.4% of the subjects affected by nonsmall cell lung cancer, but in none of the controls. The reported average frequencies of HPV in lung cancers were 17% and 15% in Europe and the Americas, respectively, and the mean number of HPV in Asian lung cancer samples

1452-462: The oropharynx , larynx , vulva , vagina , cervix , penis , and anus . These cancers all involve sexually transmitted infection of HPV to the stratified epithelial tissue . HPV type 16 is the strain most likely to cause cancer and is present in about 47% of all cervical cancers, and in many vaginal and vulvar cancers, penile cancers, anal cancers, and cancers of the head and neck. The table below lists common symptoms of HPV infection and

1518-403: The technological innovations of applied science . The two aims are often practiced simultaneously in coordinated research and development . In addition to innovations, basic research serves to provide insights and public support of nature, possibly improving conservation efforts. Technological innovations may influence engineering concepts, such as the beak of a kingfisher influencing

1584-636: The HPV infection and cervical cancer drive metabolic modifications that may be correlated with the aberrant regulation of enzymes related to metabolic pathways. Non-European (NE) HPV16 variants are significantly more carcinogenic than European (E) HPV16 variants. The risk for anal cancer is 17 to 31 times higher among HIV-positive individuals who were coinfected with high-risk HPV, and 80 times higher for particularly HIV-positive men who have sex with men. Anal Pap smear screening for anal cancer might benefit some subpopulations of men or women engaging in anal sex. No consensus exists, though, that such screening

1650-527: The National Science Foundation. A worker in basic scientific research is motivated by a driving curiosity about the unknown. When his explorations yield new knowledge, he experiences the satisfaction of those who first attain the summit of a mountain or the upper reaches of a river flowing through unmapped territory. Discovery of truth and understanding of nature are his objectives. His professional standing among his fellows depends upon

1716-549: The US FDA recently recommended approval for T-VEC, a viral therapy for melanoma manufactured by Amgen that incorporates the gene for GM-CSF to support anti-cancer immune responses. Ludwig researchers in São Paulo played a role in establishing that human papillomavirus (HPV) infection causes cervical cancer. They ran the largest epidemiological studies of HPV infection and reported that chronic, though not transient, infection by

1782-691: The United States. Although JORRP rates are substantially higher if a woman presents with genital warts at the time of giving birth, the risk of JORRP in such cases is still less than 1%. Genital HPV infections are transmitted primarily by contact with the genitals, anus, or mouth of an infected sexual partner. Of the 120 known human papilloma viruses, 51 species and three subtypes infect the genital mucosa. Fifteen are classified as high-risk types (16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, 68, 73, and 82), three as probable high-risk (26, 53, and 66), and twelve as low-risk (6, 11, 40, 42, 43, 44, 54, 61, 70, 72, 81, and 89). Condoms do not completely protect from

1848-424: The appearance of genital HPV-related diseases in newborns is rare. However, the lack of appearance does not rule out asymptomatic latent infection, as the virus has proven to be capable of hiding for decades. Perinatal transmission of HPV types 6 and 11 can result in the development of juvenile-onset recurrent respiratory papillomatosis (JORRP). JORRP is very rare, with rates of about 2 cases per 100,000 children in

1914-408: The associated types of HPV. Available HPV vaccines protect against either two, four, or nine types of HPV. There are six prophylactic HPV vaccines licensed for use: the bivalent vaccines Cervarix , Cecolin , and Walrinvax ; the quadrivalent vaccines Cervavax and Gardasil ; and the nonavalent vaccine Gardasil 9 . All HPV vaccines protect against at least HPV types 16 and 18, which cause

1980-461: The basis of progress and development in different fields. Today's computers, for example, could not exist without research in pure mathematics conducted over a century ago, for which there was no known practical application at the time. Basic research rarely helps practitioners directly with their everyday concerns; nevertheless, it stimulates new ways of thinking that have the potential to revolutionize and dramatically improve how practitioners deal with

2046-498: The body, such as the hands or feet, or even the inner thighs. A wide variety of HPV types can cause genital warts, but types 6 and 11 together account for about 90% of all cases. However, in total more than 40 types of HPV are transmitted through sexual contact and can infect the skin of the anus and genitals. Such infections may cause genital warts, although they may also remain asymptomatic. The great majority of genital HPV infections never cause any overt symptoms and are cleared by

2112-420: The cancers in the world. In the United States, high-risk HPVs cause 3% of all cancer cases in women and 2% in men. Risk factors for persistent genital HPV infections, which increases the risk for developing cancer, include early age of first sexual intercourse, multiple partners, smoking, and immunosuppression. Genital HPV is spread by sustained direct skin-to-skin contact, with vaginal, anal, and oral sex being

2178-403: The degradation of p53, induced by E6, promotes unregulated cell division, cell growth and cell survival, all characteristics of cancer. It is important to note, that while the interaction between E6, E6AP and p53 was the first to be characterized, there are multiple other proteins in the host cell which interact with E6 and assist the induction of cancer. Studies have also shown a link between

2244-527: The design of a high-speed bullet train. Basic research advances fundamental knowledge about the world. It focuses on creating and refuting or supporting theories that explain observed phenomena. Pure research is the source of most new scientific ideas and ways of thinking about the world. It can be exploratory , descriptive , or explanatory; however, explanatory research is the most common. Basic research generates new ideas, principles, and theories, which may not be immediately utilized but nonetheless form

2310-572: The development is not well understood. The specific types of HPV that are associated with EV are HPV5, HPV8, and HPV14. Sexually transmitted HPV is divided into two categories: low-risk and high-risk. Low-risk HPVs cause warts on or around the genitals. Type 6 and 11 cause 90% of all genital warts and recurrent respiratory papillomatosis that causes benign tumors in the air passages. High-risk HPVs cause cancer and consist of about twelve identified types. Types 16 and 18 are responsible for causing most of HPV-caused cancers. These high-risk HPVs cause 5% of

2376-538: The development of cancer. Co-factors such as cigarette smoke can also enhance the risk of such HPV-related cancers. HPV is believed to cause cancer by integrating its genome into nuclear DNA . Some of the early genes expressed by HPV, such as E6 and E7, act as oncogenes that promote tumor growth and malignant transformation . HPV genome integration can also cause carcinogenesis by promoting genomic instability associated with alterations in DNA copy number. E6 produces

2442-431: The development of new criteria for evaluating responses of cancer patients to immunotherapy in clinical trials. Identification of signaling pathways and subsequent development of therapeutics are examples of contributions to the field of cell signaling . The PI3K family of proteins, for example, play an important role in cell signaling that feeds cancer. This research resulted in the first Ludwig spin-off, Piramed Ltd.,

2508-774: The foreign assets from his business holdings. Upon his death in 1992, that endowment had grown to more than $ 700 million, and, as of 2012, it stands at more than $ 1.2 billion. After Ludwig's death, his US-based assets were also put into a trust to support additional cancer research efforts. These funds led to the establishment of Ludwig Centers at six research institutions in 2006. The Ludwig Institute for Cancer Research and Ludwig Centers have been known collectively as Ludwig Cancer Research since 2012. In total, Ludwig Cancer Research has committed more than US$ 2.5 billion to cancer research worldwide since 1971. The primary objectives of Ludwig Cancer Research are to prevent and control cancer through basic and translational research. Lloyd J. Old ,

2574-485: The granulocyte-monocyte colony-stimulating factor ( GM-CSF ) through a collaboration with Australian immunologist Donald Metcalf . The factor is essential to the maturation of key white blood cells, and has been used extensively over the past few decades to help rebuild the immune system of patients undergoing chemotherapy. It is also being tested as a therapeutic agent in combination with several experimental immunotherapies for cancer. The Oncology Drug Advisory Committee of

2640-503: The greatest risk of cervical cancer. The quadrivalent vaccines also protect against HPV types 6 and 11. The nonavalent vaccine Gardasil 9 provides protection against those four types (6, 11, 16, and 18), along with five other high-risk HPV types responsible for 20% of cervical cancers (types 31, 33, 45, 52, and 58). Skin infection (" cutaneous " infection) with HPV is very widespread. Skin infections with HPV can cause noncancerous skin growths called warts (verrucae). Warts are caused by

2706-446: The immune system in a matter of months. Moreover, people may transmit the virus to others even if they do not display overt symptoms of infection. Most people acquire genital HPV infections at some point in their lives, and about 10% of women are currently infected. A large increase in the incidence of genital HPV infection occurs at the age when individuals begin to engage in sexual activity. As with cutaneous HPVs, immunity to genital HPV

2772-481: The late 1970s held that spontaneously arising tumors were unlikely to elicit immune responses. Boon and his team, who believed otherwise, were the first to isolate genes that code for a family of tumor antigens and show that T cells could recognize and target cancer cells bearing such antigens. This theory is being tested in a number of current clinical trials. Ludwig researchers in Melbourne discovered and cloned

2838-411: The lung disease found that people with lung cancer had more types of HPV than noncancer patients did, and among lung cancer patients, the chances of having eight types of serious HPV were significantly increased. In addition, expression of HPV structural proteins by immunohistochemistry and in vitro studies suggest HPV presence in bronchial cancer and its precursor lesions. Another study detected HPV in

2904-407: The man's genitals infected the woman's hand with high-risk HPV, two where her hand infected his genitals, one where her genitals infected his hand, two each where he infected his own hand, and she infected her own hand. Hands were not the main source of transmission in these 25 couples, but they were significant. Partridge reports men's fingertips became positive for high risk HPV at more than half

2970-610: The most common methods. Occasionally, it can spread from manual sex or from a mother to her baby during pregnancy . HPV is difficult to remove via standard hospital disinfection techniques, and may be transmitted in a healthcare setting on re-usable gynecological equipment, such as vaginal ultrasound transducers. The period of communicability is still unknown, but probably at least as long as visible HPV lesions persist. HPV may still be transmitted even after lesions are treated and no longer visible or present. Although genital HPV types can be transmitted from mother to child during birth,

3036-450: The most common methods. HPV infection can also spread from a mother to baby during pregnancy . There is no evidence that HPV can spread via common items like toilet seats, but the types that cause warts may spread via surfaces such as floors. HPV is not killed by common hand sanitizers and disinfectants, increasing the possibility of the virus being transferred via non-living infectious agents called fomites . HPV vaccines can prevent

3102-556: The most common types of infection. To be most effective, inoculation should occur before the onset of sexual activity, and are therefore recommended between the ages of 9–13 years. Cervical cancer screening , such as the Papanicolaou test ("pap smear"), or examination of the cervix after applying acetic acid , can detect both early cancer and abnormal cells that may develop into cancer. Screening allows for early treatment which results in better outcomes. Screening has reduced both

3168-415: The number of cases and the number of deaths from cervical cancer. Genital warts can be removed by freezing . Nearly every sexually active individual is infected by HPV at some point in their lives. HPV is the most common sexually transmitted infection (STI) , globally. High-risk HPVs cause about 5% of all cancers worldwide and about 37,300 cases of cancer in the United States each year. Cervical cancer

3234-452: The organization's former director, and scientific chairman, participated in the discovery of Tumor Necrosis Factor (TNF) and the tumor suppressor p53 . He contributed to the immunosurveillance hypothesis, from which modern cancer immunotherapy can be derived. Thierry Boon , former director of the organization's Brussels branch, made foundational contributions to the field of cancer immunotherapy. The prevailing model of carcinogenesis in

3300-510: The organization's worldwide efforts. It was announced in December 2016 that Chi Van Dang would take over the role of Scientific Director in July 2017. He is responsible for coordinating the organization's global research efforts and activities. Notable awards received by past and present employees affiliated with Ludwig include: Nobel Prize : National Medal of Science (US): Fellows of

3366-468: The originality and soundness of his work. Creativeness in science is of a cloth with that of the poet or painter. It conducted a study in which it traced the relationship between basic scientific research efforts and the development of major innovations, such as oral contraceptives and videotape recorders. This study found that basic research played a key role in the development in all of the innovations. The number of basic science research that assisted in

In short, p53 is a tumor-suppressor protein that arrests the cell cycle and prevents cell growth and survival when DNA damage occurs. Thus,

3498-766: The production of a given innovation peaked between 20 and 30 years before the innovation itself. While most innovation takes the form of applied science and most innovation occurs in the private sector, basic research is a necessary precursor to almost all applied science and associated instances of innovation. Roughly 76% of basic research is conducted by universities. A distinction can be made between basic science and disciplines such as medicine and technology. They can be grouped as STM (science, technology, and medicine; not to be confused with STEM [science, technology, engineering, and mathematics]) or STS (science, technology, and society). These groups are interrelated and influence each other, although they may differ in

3564-699: The rate (26% per two years) as their genitals (48%). Winer reports 14% of fingertip samples from sexually active women were positive. Non-sexual hand contact seems to have little or no role in HPV transmission. Winer found all fourteen fingertip samples from virgin women negative at the start of her fingertip study. In a separate report on genital HPV infection, 1% of virgin women (1 of 76) with no sexual contact tested positive for HPV, while 10% of virgin women reporting non-penetrative sexual contact were positive (7 of 72). Sharing of possibly contaminated objects, for example, razors, may transmit HPV. Although possible, transmission by routes other than sexual intercourse

3630-721: The rate has continued to increase. Researchers explain these recent data by an increase in oral sex. This type of cancer is more common in men than in women. The mutational profile of HPV-positive and HPV-negative head and neck cancer has been reported, further demonstrating that they are fundamentally distinct diseases. Some evidence links HPV to benign and malignant tumors of the upper respiratory tract. The International Agency for Research on Cancer has found that people with lung cancer were significantly more likely to have several high-risk forms of HPV antibodies compared to those who did not have lung cancer. Researchers looking for HPV among 1,633 lung cancer patients and 2,729 people without

3696-457: The scientific foundation for applied science. Basic science develops and establishes information to predict phenomena and perhaps to understand nature, whereas applied science uses portions of basic science to develop interventions via technology or technique to alter events or outcomes. Applied and basic sciences can interface closely in research and development . The interface between basic research and applied research has been studied by

3762-514: The site affected, increase the risk of cancer of the cervix , vulva , vagina , penis , anus , mouth, tonsils, or throat . Nearly all cervical cancer is due to HPV, and two strains – HPV16 and HPV18 – account for 70% of all cases. HPV16 is responsible for almost 90% of HPV-positive oropharyngeal cancers . Between 60% and 90% of the other cancers listed above are also linked to HPV. HPV6 and HPV11 are common causes of genital warts and laryngeal papillomatosis . An HPV infection

3828-409: The skin in the genital area is the most common sexually transmitted infection worldwide. Such infections are associated with genital or anal warts (medically known as condylomata acuminata or venereal warts), and these warts are the most easily recognized sign of genital HPV infection. The strains of HPV that can cause genital warts are usually different from those that cause warts on other parts of

3894-438: The skin. Although these latent infections may never be fully eradicated, immunological control is thought to block the appearance of symptoms such as warts. Immunological control is HPV type-specific, meaning an individual may become resistant to one HPV type while remaining susceptible to other types. Types of warts include: Common, flat, and plantar warts are much less likely to spread from person to person. HPV infection of

3960-809: The specifics such as methods and standards. The Nobel Prize mixes basic with applied sciences for its award in Physiology or Medicine . In contrast, the Royal Society of London awards distinguish natural science from applied science. Human papillomavirus Human papillomavirus infection ( HPV infection ) is caused by a DNA virus from the Papillomaviridae family. Many HPV infections cause no symptoms and 90% resolve spontaneously within two years. In some cases, an HPV infection persists and results in either warts or precancerous lesions . These lesions, depending on

4026-426: The virus because the areas around the genitals including the inner thigh area are not covered, thus exposing these areas to the infected person's skin. Studies have shown HPV transmission between hands and genitals of the same person and sexual partners. Hernandez tested the genitals and dominant hand of each person in 25 heterosexual couples every other month for an average of seven months. She found two couples where

4092-440: The virus dramatically increases the risk of cervical cancer, laying the groundwork for the clinical development of an HPV vaccine. Current and former Ludwig researchers contributed to an emerging class of cancer immunotherapies known as checkpoint inhibitors . They explored the underlying immunology of the response and played a role in evaluating the first such drug in clinical trials for the treatment of advanced melanoma. This led

4158-611: The warts may be advisable. Cervical cancer is among the most common cancers worldwide, causing an estimated 604,000 new cases and 342,000 deaths in 2020. About 90% of these new cases and deaths of cervical cancer occurred in low- and middle-income countries , where screening tests and treatment of early cervical cell changes are not readily available. In the United States, about 37,300 cases of cancer due to HPV occur each year. In some infected individuals, their immune systems may fail to control HPV. Lingering infection with high-risk HPV types, such as types 16, 18, 31, and 45, can favor

4224-554: The “ War on Cancer ,” declared by his friend President Richard Nixon , led to the establishment of the US National Cancer Institute . Ludwig believed that tackling the problem of cancer required the best minds operating in the most favorable conditions with the best resources to accomplish the task. This principle continues to guide Ludwig Cancer Research. Daniel K. Ludwig endowed the Institute with all of

4290-420: Was 35.7%, with a considerable heterogeneity between certain countries and regions. In very rare cases, HPV may cause epidermodysplasia verruciformis (EV) in individuals with a weakened immune system . The virus, unchecked by the immune system, causes the overproduction of keratin by skin cells , resulting in lesions resembling warts or cutaneous horns which can ultimately transform into skin cancer , but

Born in South Haven , Michigan in 1897, he used a $ 5,000 loan from his father to create a global business based on a fleet of supertankers . In the 1960s and 1970s, Ludwig was among the richest men in the world, owning approximately 200 companies. He founded the Ludwig Institute for Cancer Research as an independent organization in 1971, the same year that
