Nicotinic Receptors: Role in Addiction and Other Disorders of the Brain
Substance Abuse: Research and Treatment, 2008 Nicotine, the addictive component of cigarette smoke has profound effects on the brain. Activation of its receptors by nicotine has complex consequences for network activity throughout the brain, potentially contributing to the addictive property of the ...

A physical model of nicotinic ACh receptor kinetics [PDF]
arXiv, 2008 We present a new approach to nicotinic receptor kinetics and a new model explaining random variabilities in the duration of open events. The model gives new interpretation on brief and long receptor openings and predicts (for two identical binding sites) the presence of three components in the open time distribution: two brief and a long.

Cytoplasmic nanojunctions between lysosomes and sarcoplasmic reticulum are required for specific calcium signaling [PDF]
, 2014 We demonstrate how nanojunctions between lysosomes and sarcoplasmic reticulum (L-SR junctions) serve to couple lysosomal activation to regenerative, ryanodine receptor-mediated cellular calcium (Ca2+) waves. In pulmonary artery smooth muscle cells (PASMCs) nicotinic acid adenine dinucleotide phosphate (NAADP) may trigger increases in cytoplasmic Ca2 ...

PROTEOMICS, Volume 22, Issue 23-24, December 2022., 2022 Abstract The X‐linked inherited neuromuscular disorder Duchenne muscular dystrophy is characterised by primary abnormalities in the membrane cytoskeletal component dystrophin. The almost complete absence of the Dp427‐M isoform of dystrophin in skeletal muscles renders contractile fibres more susceptible to progressive degeneration and a leaky ...
