Neuronal nicotinic receptors are comprised of combinations of alpha(2-9) and beta(2-4) subunits arranged to form a pentameric receptor. Currently, the principal central nervous system (CNS) subtypes are believed to be alpha(4)beta(2) and a homomeric alpha(7) receptor, although other combinations
Investigation of the naturally occurring, nicotinic agonist anabaseine and novel derivatives has shown that these compounds have cytoprotective and memory-enhancing effects. The hypothesis that these arise at least in part through actions on brain nicotinic receptors was evaluated by examining the
Abnormal sensory inhibition is a measurable indicator of a sensory processing deficit which is observed in schizophrenia, and other disorders, and which may be heritable. This deficit has also been observed in certain inbred mouse strains where the intensity of the deficit has been correlated with
1. The aim of this study was to compare the effects of chronic treatment (for 4 or 7 days) with nicotinic drugs and 20 mM KCl on numbers of surface alpha7 nicotinic AChR, identified by [(125)I]-alpha bungarotoxin (alpha-Bgt) binding, in primary hippocampal cultures and SH-SY5Y cells. Numbers of
