Memetic Algorithms for Ligand Expulsion from Protein Cavities [PDF]
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

Interactions between the neuromodulatory systems and the amygdala: exploratory survey using the Allen Mouse Brain Atlas. [PDF]
Neuromodulatory systems originate in nuclei localized in the subcortical region of the brain and control fundamental behaviors by interacting with many areas of the central nervous system.

Tiotropium suppresses acetylcholine-induced release of chemotactic mediators in vitro [PDF]
SummaryThe driving force in the progression of COPD is the development of exacerbations which are mostly the result of excessive inflammation. Bronchodilatators play an important role in the treatment of COPD. The reported reduction in exacerbation rates

Selective inhibition of M5 muscarinic acetylcholine receptors attenuates cocaine self‐administration in rats [PDF]
AbstractCocaine use disorder (CUD) remains a debilitating health problem in the United States for which there are no Food and Drug Administration‐approved treatment options. Accumulating anatomical and electrophysiological evidence indicates that the muscarinic acetylcholine receptor (mAChR) subtype 5 (M5) plays a critical role in the regulation of the

The membrane signaling properties of the neuronal type-5 muscarinic acetylcholine receptor (M5 AChR) as expressed in murine L cells were studied. Recipient Ltk- cells responded to ATP acting through a P2-purinergic receptor by increasing phosphoinositide hydrolysis 2-fold but were unresponsive to 17 receptor agonists that are stimulatory in other cells.

Carbachol‐induced reverse transformation of Chinese hamster ovary cells transfected with and expressing the m5 muscarinic acetylcholine receptor [PDF]
Reverse transformation was induced in Chinese hamster ovary (CHO) cells transfected with and stably expressing the m5 subtype of the muscarinic acetylcholine receptor when stimulated with the muscarinic agonist, carbachol. Atropine, a muscarinic antagonist, blocked the carbachol‐stimulated reverse transformation.

Antidepressant-like Effects of Neuropeptide SF (NPSF) [PDF]
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 ...

Dopamine Signaling in Dorsal Versus Ventral Striatum: The Dynamic Role of Cholinergic Interneurons [PDF]
Mesostriatal dopaminergic neurons and striatal cholinergic interneurons participate in signaling the motivational signifcance of environmental stimuli and regulate striatal plasticity. Dopamine (DA) and acetylcholine (ACh) have potent interactions within

GPCR‐G protein signalling and its mutational landscape in cancer—Driver or passenger
G protein‐coupled receptors (GPCRs) play a crucial role in cellular signalling, regulating various physiological processes. Abnormal expression and mutations of GPCRs have been implicated in several types of cancer, influencing tumour initiation, progression and immune response.

Besides some pharmacological, biochemical and biophysical evidences support the contention that muscarinic acetylcholine receptors can form homo- and heterodimers, the existence of specific M3 and M5 muscarinic receptors oligomers in living cells is a new concept.
