Differing time dependencies of object recognition memory impairments produced by nicotinic and muscarinic cholinergic antagonism in perirhinal cortex [PDF]

, 2011
The roles of muscarinic and nicotinic cholinergic receptors in perirhinal cortex in object recognition memory were compared. Rats' discrimination of a novel object preference test (NOP) test was measured after either systemic or local infusion into the ...

Nicotinic potentiation of frog retinotectal transmission in tectum layer F by α3β2, α4β2, α2β4, α6β2, or α7 acetylcholine receptor subtypes

Medicina, 2015
Objective: The aim of the study was to explore the effect of semi-specific antagonists and agonists of the nicotinic acetylcholine receptors on the paired-pulse facilitation and nicotinic tonic and phasic potentiation of the frog retinotectal synaptic ...

Activation of α7 nicotinic acetylcholine receptor by nicotine selectively up-regulates cyclooxygenase-2 and prostaglandin E₂ in rat microglial cultures

Journal of Neuroinflammation, 2005
Background Nicotinic acetylcholine (Ach) receptors are ligand-gated pentameric ion channels whose main function is to transmit signals for the neurotransmitter Ach in peripheral and central nervous system.

Venomous secretions from marine snails of the Terebridae family target acetylcholine receptors [PDF]

, 2013
Venoms from cone snails (Conidae) have been extensively studied during the last decades, but those from other members of the suborder Toxoglossa, such as of Terebridae and Turridae superfamilies attracted less interest so far. Here, we report the effects

Loop B is a major structural component of the 5-HT3 receptor [PDF]

, 2008
The 5-HT3 receptor belongs to a family of therapeutically important neurotransmitter-gated receptors whose ligand binding sites are formed by the convergence of six peptide loops (A-F).

Possible Involvement of Endogenous Opioid System Located Downstream of α7 Nicotinic Acetylcholine Receptor in Mice With Physical Dependence on Nicotine

Journal of Pharmacological Sciences, 2014
.: We previously reported that nicotine (NIC)-induced analgesia was elicited in part by activation of the endogenous opioid system. Moreover, it is well known that NIC has physical-dependence liability, but its mechanism is unclear.
