Functional Stoichiometry at the Nicotinic Receptor. The Photon Cross Section for Phase 1 Corresponds to Two Bis-Q Molecules per Channel [PDF]
These experiments examine changes in the agonist-induced conductance that occur when the agonist-receptor complex is perturbed. Voltage-clamped Electrophorus electroplaques are exposed to the photoisomerizable agonist trans-Bis-Q A 1-µs laser flash ...

Nicotinic acetylcholine receptor agonist attenuates ILC2-dependent airway hyperreactivity
Airway hyperreactivity is driven by type 2 cytokines produced by ILC2 and Th2 cells. Here the authors show that an α7-nicotinic receptor agonist (GTS-21) inhibits ILC2 responses and is therapeutic against Alternaria-induced airway hyperreactivity in a ...

Conditional expression in corticothalamic efferents reveals a developmental role for nicotinic acetylcholine receptors in modulation of passive avoidance behavior [PDF]
Prenatal nicotine exposure has been linked to attention deficit hyperactivity disorder and cognitive impairment, but the sites of action for these effects of nicotine are still under investigation. High-affinity nicotinic acetylcholine receptors (nAChRs)

A photoisomerizable muscarinic antagonist. Studies of binding and of conductance relaxations in frog heart [PDF]
These experiments employ the photoisomerizable compound, 3,3'-bis- [alpha-(trimethylammonium)methyl]azobenzene (Bis-Q), to study the response to muscarinic agents in frog myocardium. In homogenates from the heart, trans-Bis-Q blocks the binding of [3H]-N-
