148-496: A result of long term drug use are amyloid beta (Aβ), glutamate , dopamine , and oxygen radicals . When present in high concentrations, they can lead to neurotoxicity and death ( apoptosis ). Some of the symptoms that result from cell death include loss of motor control, cognitive deterioration and autonomic nervous system dysfunction. Additionally, neurotoxicity has been found to be a major cause of neurodegenerative diseases such as Alzheimer's disease (AD). Amyloid beta (Aβ)

185-454: Is a chemical found in the brain that poses a toxic threat to neurons when found in high concentrations. This concentration equilibrium is extremely delicate and is usually found in millimolar amounts extracellularly. When disturbed, an accumulation of glutamate occurs as a result of a mutation in the glutamate transporters , which act like pumps to clear glutamate from the synapse. This causes glutamate concentration to be several times higher in

222-509: Is a form of toxicity in which a biological, chemical, or physical agent produces an adverse effect on the structure or function of the central and/or peripheral nervous system . It occurs when exposure to a substance – specifically, a neurotoxin or neurotoxicant – alters the normal activity of the nervous system in such a way as to cause permanent or reversible damage to nervous tissue .

444-458: The central nervous system to cause cell death. An example is through the nicotinic acetylcholine receptor (nAchRs), which is a receptor commonly found along the surfaces of the cells that respond to nicotine stimulation, turning them on or off. Aβ was found manipulating the level of nicotine in the brain along with the MAP kinase , another signaling receptor, to cause cell death. Another chemical in

481-463: The Ca and NOS results in the formation of the cofactor tetrahydrobiopterin (BH4), which then moves from the plasma membrane into the cytoplasm. As a final step, NOS is dephosphorylated yielding nitric oxide (NO), which accumulates in the brain, increasing its oxidative stress . There are several ROS, including superoxide , hydrogen peroxide and hydroxyl , all of which lead to neurotoxicity. Naturally,

UMH is continuously interested in fostering its international relations and expanding its number of foreign partners. The UMH organizes language courses in English, French, German, Italian, Portuguese, and Spanish as

703-412: The activation of nitric oxide synthase , ultimately leading to cell death. Aβ was also found aiding this route to neurotoxicity by enhancing neuron vulnerability to glutamate. The formation of oxygen radicals in the brain is achieved through the nitric oxide synthase (NOS) pathway. This reaction occurs as a response to an increase in the Ca concentration inside a brain cell. This interaction between

740-427: The blood than in the brain; in turn, the body must act to maintain equilibrium between the two concentrations by pumping the glutamate out of the bloodstream and into the neurons of the brain. In the event of a mutation, the glutamate transporters are unable to pump the glutamate back into the cells; thus a higher concentration accumulates at the glutamate receptors . This opens the ion channels, allowing calcium to enter

777-635: The body utilizes a defensive mechanism to diminish the fatal effects of the reactive species by employing certain enzymes to break down the ROS into small, benign molecules of simple oxygen and water. However, this breakdown of the ROS is not completely efficient; some reactive residues are left in the brain to accumulate, contributing to neurotoxicity and cell death. The brain is more vulnerable to oxidative stress than other organs, due to its low oxidative capacity. Because neurons are characterized as postmitotic cells, meaning that they live with accumulated damage over

814-863: The brain and other parts of the nervous system. Neurotoxicity can result from organ transplants , radiation treatment , certain drug therapies , recreational drug use , exposure to heavy metals , bites from certain species of venomous snakes , pesticides , certain industrial cleaning solvents , fuels and certain naturally occurring substances. Symptoms may appear immediately after exposure or be delayed. They may include limb weakness or numbness, loss of memory, vision, and/or intellect, uncontrollable obsessive and/or compulsive behaviors, delusions, headache, cognitive and behavioral problems and sexual dysfunction. Chronic mold exposure in homes can lead to neurotoxicity which may not appear for months to years of exposure. All symptoms listed above are consistent with mold mycotoxin accumulation. The term neurotoxicity implies

851-444: The brain that Aβ regulates is JNK ; this chemical halts the extracellular signal-regulated kinases (ERK) pathway, which normally functions as memory control in the brain. As a result, this memory favoring pathway is stopped, and the brain loses essential memory function. The loss of memory is a symptom of neurodegenerative disease , including AD. Another way Aβ causes cell death is through the phosphorylation of AKT ; this occurs as

925-481: The cell causing excitotoxicity. Glutamate results in cell death by turning on the N-methyl-D-aspartic acid receptors (NMDA); these receptors cause an increased release of calcium ions (Ca ) into the cells. As a result, the increased concentration of Ca directly increases the stress on mitochondria , resulting in excessive oxidative phosphorylation and production of reactive oxygen species (ROS) via

1110-405: The involvement of a neurotoxin; however, the term neurotoxic may be used more loosely to describe states that are known to cause physical brain damage , but where no specific neurotoxin has been identified. The presence of neurocognitive deficits alone is not usually considered sufficient evidence of neurotoxicity, as many substances may impair neurocognitive performance without resulting in

1147-427: The pathology of Parkinson's disease . Certain drugs, most famously the pesticide and metabolite MPP+ (1-methyl-4-phenylpyridin-1-ium) can induce Parkinson's disease by destroying dopaminergic neurons in the substantia nigra . MPP+ interacts with the electron transport chain in the mitochondria to generate reactive oxygen species which cause generalized oxidative damage and ultimately cell death. MPP+

1184-567: The phosphate group is bound to several sites on the protein. This phosphorylation allows AKT to interact with BAD , a protein known to cause cell death. Thus an increase in Aβ results in an increase of the AKT/BAD complex, in turn stopping the action of the anti-apoptotic protein Bcl-2 , which normally functions to stop cell death, causing accelerated neuron breakdown and the progression of AD. Glutamate

DOPAL may play an important role in

1369-410: Was found to cause neurotoxicity and cell death in the brain when present in high concentrations. Aβ results from a mutation that occurs when protein chains are cut at the wrong locations, resulting in chains of different lengths that are unusable. Thus they are left in the brain until they are broken down, but if enough accumulate, they form plaques which are toxic to neurons . Aβ uses several routes in
