Lynx1 Modulation of Nicotinic Acetylcholine Receptors [PDF]

, 2015
Nicotinic receptors are the target of nicotine in the brain. They are pentameric ion channels. The pentamer structure allows many combinations of receptors to be formed.

Hederagenin Attenuates Morphine Addiction via GABAA1‐Mediated Modulation of Ca2+–CaMK–CREB Signaling in Ventral Tegmental Dopaminergic Neurons

Advanced Science, EarlyView.
Hederagenin is identified as a GABAA1‐targeting natural compound that suppresses morphine‐associated reward by restraining Ca2+–CaMK–cAMP–CREB signaling in ventral tegmental dopaminergic neurons. RVG29‐modified liposomal delivery further enhances brain accumulation and behavioral efficacy, providing a mechanistically defined strategy for natural ...

Recombinant glycine receptors: stoichiometry and kinetics [PDF]

, 2009
Glycine receptors (GlyR) are anion-permeable channels that belong to the pentameric ligand-gated ion channel family. Different GlyR subtypes are known. The main synaptic form is thought to be α1β heteropentamers which mediate fast synaptic inhibition in ...

Extracellular Vesicle Packaged TDP43 Derived From ECs Exacerbates Cigarette Tar‐Related Atherosclerosis Progression via Enhancing Macrophage Extracellular Traps

Advanced Science, EarlyView.
Cigarette tar triggers EC‐derived EVs carrying TDP43, which binds VDAC1 to boost MAMs, mitochondrial Ca2+ overload, and METs formation in macrophages, accelerating smoking‐related AS progression, while retinoic acid binds TDP43 to block this pathogenic cascade.

Single channel study of the spasmodic mutation α1A52S in recombinant rat glycine receptors [PDF]

, 2007
Inherited defects in glycine receptors lead to hyperekplexia, or startle disease. A mutant mouse, spasmodic, that has a startle phenotype, has a point mutation (A52S) in the glycine receptor α1 subunit.
