Nicotinic and muscarinic property of ACh receptors on cultured brain stem neurons.
Using cultures of dissociated neurons from the lower brain stem of rat embryos, the receptor properties of cholinoceptive neurons were examined pharmacologically. Out of 89 neurons, 41 showed facilitation of unit discharges by the application of acetylcholine. These cholinoceptive neurons were proven to have both nicotinic and muscarinic properties.
متن کاملMuscarinic receptors couple to modulation of nicotinic ACh receptor desensitization in myenteric neurons.
Signaling mechanisms coupled to activation of different neurotransmitter receptors interact in the enteric nervous system. ACh excites myenteric neurons by activating nicotinic ACh receptors (nAChRs) and muscarinic receptors expressed by the same neurons. These studies tested the hypothesis that muscarinic receptor activation alters the functional properties of nAChRs in guinea pig small intest...
متن کاملExpression and function of neuronal nicotinic ACh receptors in rat microvascular endothelial cells.
The expression and function of nicotinic ACh receptors (nAChRs) in rat coronary microvascular endothelial cells (CMECs) were examined using RT-PCR and whole cell patch-clamp recording methods. RT-PCR revealed expression of mRNA encoding for the subunits alpha(2), alpha(3), alpha(4), alpha(5), alpha(7), beta(2), and beta(4) but not beta(3). Focal application of ACh evoked an inward current in is...
متن کاملActivation and inhibition of native neuronal alpha-bungarotoxin-sensitive nicotinic ACh receptors.
Tuberomammillary histamine neurons (TM) of the posterior hypothalamus exclusively express alpha-bungarotoxin (alphaBgt) sensitive nicotinic receptors, providing a unique model system for studying physiological properties of native alpha7-like receptors. Here the properties of alphaBgt-sensitive receptors were investigated using the patch-clamp technique and rapid application of acetylcholine (A...
متن کاملMuscarinic ACh Receptors Contribute to Aversive Olfactory Learning in Drosophila
The most studied form of associative learning in Drosophila consists in pairing an odorant, the conditioned stimulus (CS), with an unconditioned stimulus (US). The timely arrival of the CS and US information to a specific Drosophila brain association region, the mushroom bodies (MB), can induce new olfactory memories. Thus, the MB is considered a coincidence detector. It has been shown that olf...
