Chemical chaperones exceed the chaperone effects of RIC-3 in promoting assembly of functional α7 AChRs. [PDF]
Functional α7 nicotinic acetylcholine receptors (AChRs) do not assemble efficiently in cells transfected with α7 subunits unless the cells are also transfected with the chaperone protein RIC-3.

This diagram illustrates opposing pathways regulating AKI (acute kidney injury). The left pathway shows LPS/TLR4 triggering mitochondrial damage (low MMP, Cyt C release, ROS) leading to apoptosis. The right pathway shows α7nAChR agonists activating MEF2 to upregulate PGC‐1α/HO‐1, promoting mitochondrial biogenesis and inhibiting injury, highlighting ...

Abstract Introduction Maternal obesity is highly prevalent worldwide, conferring elevated risks of maternal/fetal complications and adult‐onset disease in offspring. Obesity and pregnancy are both states of insulin resistance. Percutaneous electrical stimulation of skeletal muscle, better known as electroacupuncture (EA), mitigates insulin resistance ...

In neonatal mice motoneurons excite Renshaw cells by releasing both acetylcholine (ACh) and glutamate. These two neurotransmitters activate two types of nicotinic receptors (nAChRs) (the homomeric α7 receptors and the heteromeric α*ß* receptors) as well

Nicotinic acetylcholine receptors containing the α7-like subunit mediate contractions of muscles responsible for space positioning of the snail, Helix pomatia L. tentacle. [PDF]
Three recently discovered tentacle muscles are crucial to perform patterned movements of upper tentacles of the terrestrial snail, Helix pomatia. The muscles receive central and peripheral excitatory cholinergic innervation lacking inhibitory innervation.

Human α7 receptors have been characterised in terms of pharmacological properties. Insertion of the N‐terminal domain of the human α7 subunit leads to honeybee and cockroach chimeric receptors activated by ACh and inhibited by α‐Bgt. Insertion of the human cys‐loop leads to cockroach chimeric receptors modulated by PNU.

Calcium imaging with genetically encoded sensor Case12: Facile analysis of α7/α9 nAChR mutants.
Elucidation of the structural basis of pharmacological differences for highly homologous α7 and α9 nicotinic acetylcholine receptors (nAChRs) may shed light on their involvement in different physiological functions and diseases.

Adolescent Exposure to Nicotine and Ethanol Attenuates Adult Nicotine Reward Sensitivity in Rats
We investigated how chronic exposure to nicotine, ethanol, or their combination during adolescence influences adult conditioned place preference (CPP) for nicotine. No significant CPP was observed in any of the drug‐exposed groups, suggesting adolescent exposure to addictive substances does not uniformly increase vulnerability to nicotine reward ...

Surgery‐induced MS/vDB → DG cholinergic decline impairs hippocampal neurogenesis and memory in aged mice; galantamine‐mediated cholinergic potentiation or sustained chemogenetic activation rescues these deficits, highlighting therapeutic potential for POCD.
