Neurotransmitters altering

Some trichothecene-induced effects may be due to neurotransmitter alteration in the central nervous system. Emesis or vomiting, which occurs with many of the trichothecenes when given at high doses, has been attributed to the stimulation of the chemoreceptor trigger zone in the area postrema of the medulla oblongata. However, studies with T-2 toxin in cats indicated that other mechanisms, such as the neural afferent pathways from the abdomen, implicated in radiation-induced emesis, may also be involved (Borison and Goodheart, 1989). DON alters serotonin activity in the central nervous system of swine which is important in... [Pg.357]

A subset of ion channels not gated by traditional neurotransmitters represents another receptor class. These iaclude potassium, calcium, sodium, and cychc adenosiae monophosphate (cAMP)-gated channels (14—16) for which a large number of synthetic molecules exist that alter ceUular function. [Pg.518]

Neurotransmitter. A substance that is released from one neuron as a result of depolarization and in turn alters the excitability of adjacent neurons. [Pg.453]

Cocaine- and amphetamine-regulated transcript (CART) peptides are putative neurotransmitters are found in those dopaminergic brain regions. Stimulants seem to alter CART mRNA and peptide levels [2]. [Pg.1040]

Acute exposure to large amounts of endosulfan results in frank effects manifested as hyperactivity, muscle tremors, ataxia, and convulsions. Possible mechanisms of toxicity include (a) alteration of neurotransmitter levels in brain areas by affecting synthesis, degradation, and/or rates of release and reuptake, and/or (b) interference with the binding of those neurotransmitter to their receptors. [Pg.141]

While brain serotonin systems may play a key role in mediating some of the effects of MDMA on analgesia and body temperature as well as in the reported anxiolytic-like and mood-altering subjective effects of the drug, additional neurotransmitter systems may contribute to some of the unique subjective experiences reported for MDMA and other drugs in this class. [Pg.253]
