A Hydrophobic Gate in an Ion Channel: The Closed State of the Nicotinic Acetylcholine Receptor [PDF]
Physical Biology, 3(2):147-159, 2006, 2005 The nicotinic acetylcholine receptor (nAChR) is the prototypic member of the `Cys-loop' superfamily of ligand-gated ion channels which mediate synaptic neurotransmission, and whose other members include receptors for glycine, gamma-aminobutyric acid, and serotonin.

Alpha7 nicotinic acetylcholine receptor signaling modulates ovine fetal brain astrocytes transcriptome in response to endotoxin [PDF]
Front. Immunol. 2019, 2018 Neuroinflammation in utero may result in lifelong neurological disabilities. Astrocytes play a pivotal role, but the mechanisms are poorly understood. No early postnatal treatment strategies exist to enhance neuroprotective potential of astrocytes. We hypothesized that agonism on alpha7 nicotinic acetylcholine receptor (alpha7nAChR) in fetal astrocytes

The Cholinergic Pathways in Inflammation: A Potential Pharmacotherapeutic Target for COPD
Frontiers in Pharmacology, 2018 In COPD, the activity of the cholinergic system is increased, which is one of the reasons for the airflow limitation caused by the contraction of airway smooth muscles.

Memetic Algorithms for Ligand Expulsion from Protein Cavities [PDF]
J. Chem. Phys. 143 (12), 124101, 2015, 2015 Ligand diffusion through proteins is a fundamental process governing biological signaling and enzymatic catalysis. The complex topology of protein tunnels results in difficulties with computing ligand escape pathways by standard molecular dynamics (MD) simulations. Here, two novel methods for searching of ligand exit pathways and cavity exploration are

Antidepressant-like Effects of Neuropeptide SF (NPSF) [PDF]
World Journal of Research and Review (WJRR) ISSN:2455-3956,
Volume-4, Issue-5, May 2017 Pages 26-30, 2020 Neuropeptide SF (NPSF) is a member of RFamide neuropeptides that play diverse roles in central nervous system. Little is know about the effects of NPSF on brain functions. Antidepressant-like effect of NPSF was studied in modified mice FST. NPSF showed the antidepressant-like effects by decreasing the immobility time and increasing the climbing and ...
