Nicotinic receptors regulate B lymphocyte activation and immune response.

9 Jul 2005 The presence of nicotinic acetylcholine receptors (nicotinic receptors) composed of either alpha7 or alpha4 and beta2 subunits is revealed in B lymphocytes by means of radioligand binding assay and Cell ELISA. Mouse B lymphocytes contained ...

Effects of moderate chronic ethanol consumption on hippocampal nicotinic receptors and associative learning.

8 Mar 2008 A number of studies have reported that ethanol exposure induces changes in different brain systems. The hippocampus is a brain region that is very vulnerable to ethanol exposition, which functionally results in impairment of learning and memory ...

Involvement of dorsal hippocampal nicotinic receptors in the effect of morphine on memory retrieval in passive avoidance task.

17 Feb 2008 The present study evaluated the possible role of nicotinic acetylcholine receptors of the dorsal hippocampus on morphine-induced amnesia and morphine state-dependent memory in adult male Wistar rats. The animals were bilaterally implanted with ...

Muscarinic and nicotinic receptors synergistically modulate working memory and attention in humans.

7 May 2005 Functional abnormalities in muscarinic and nicotinic receptors are associated with a number of disorders including Alzheimer's disease and schizophrenia. While the contribution of muscarinic receptors in modulating cognition is well established in ...

Dorsal hippocampal alpha7 and alpha4beta2 nicotinic receptors and memory.

21 Mar 2006 Nicotinic receptor systems have been shown to be important for working memory. In general, nicotinic agonists have been shown to improve memory, and nicotinic antagonists impair it. All of the neuronal substrates for nicotinic involvement in memory ...

Kynurenic acid blocks nicotinic synaptic transmission to hippocampal interneurons in young rats.

23 Apr 2007 The tryptophan metabolite kynurenic acid can block glutamate at ionotropic receptors, but recent evidence suggests a more potent antagonistic action at alpha7 nicotinic receptors for acetylcholine on cultured neurons. The present study examines ...

Molecular determinants of pyrantel selectivity in nicotinic receptors.

4 Jul 2006 Nicotinic receptors (acetylcholine receptors, AChRs) play key roles in synaptic transmission throughout the nervous system. AChRs mediate neuromuscular transmission in nematodes, and they are targets for antiparasitic drugs. The anthelmintic agents ...

Cholinergic axons modulate GABAergic signaling among hippocampal interneurons via postsynaptic alpha 7 nicotinic receptors.

21 May 2007 Homopentameric alpha7 nicotinic receptors have a high affinity for acetylcholine (ACh), are permeable to Ca2+ ions, and are abundant in hippocampal interneurons. Although nicotinic agonists evoke inward currents and Ca2+ transients in stratum ...

Perinatal exposure to nicotine causes deficits associated with a loss of nicotinic receptor function.

26 Feb 2005 We investigated the role played by beta2-containing neuronal nicotinic receptors [nicotinic acetylcholine receptors (nAChRs)] in mediating nicotine's side effects in the fetus and newborn. Pregnant WT and mutant mice lacking the beta2 nAChR subunit ...

Expression of functional nicotinic acetylcholine receptors in rat urinary bladder epithelial cells.

4 Sep 2005 Although nicotinic acetylcholine receptors in both the central and peripheral nervous systems play a prominent role in the control of urinary bladder function, little is known regarding expression or function of nicotinic receptors in the bladder ...
