Molecular determinants involved in the allosteric control of agonist affinity in the GABAB receptor by the GABAB2 subunit [PDF]
The Journal of Biological Chemistry 279, 16 (2004) 15824-30, 2008 The gamma-aminobutyric acid type B (GABAB) receptor is an allosteric complex made of two subunits, GABAB1 (GB1) and GABAB2 (GB2). Both subunits are composed of an extracellular Venus flytrap domain (VFT) and a heptahelical domain (HD). GB1 binds GABA, and GB2 plays a major role in G-protein activation as well as in the high agonist affinity state of ...

Communication over the network of binary switches regulates the activation of A$_{2A}$ adenosine receptor [PDF]
PLoS Comp. Biol. (2015) 11(2): e1004044, 2014 Dynamics and functions of G-protein coupled receptors (GPCRs) are accurately regulated by the type of ligands that bind to the orthosteric or allosteric binding sites. To glean the structural and dynamical origin of ligand-dependent modulation of GPCR activity, we performed total $\sim$ 5 $\mu$sec molecular dynamics simulations of A$_{2A}$ adenosine ...

Novel Roles for Kv7 Channels in Shaping Histamine-Induced Contractions and Bradykinin-Dependent Relaxations in Pig Coronary Arteries. [PDF]
PLoS ONE, 2016 Voltage-gated Kv7 channels are inhibited by agonists of Gq-protein-coupled receptors, such as histamine. Recent works have provided evidence that inhibition of vascular Kv7 channels may trigger vessel contractions.

PKC-dependent Phosphorylation of the H1 Histamine Receptor Modulates TRPC6 Activity
Cells, 2014 Transient receptor potential canonical 6 (TRPC6) is a cation selective, DAG-regulated, Ca2+-permeable channel activated by the agonists of Gq-protein-coupled heptahelical receptors.

Neuroreceptor Activation by Vibration-Assisted Tunneling [PDF]
Scientific Reports 5, Article number: 9990 Published 2015, 2015 G protein-coupled receptors (GPCRs) constitute a large family of receptor proteins that sense molecular signals on the exterior of a cell and activate signal transduction pathways within the cell. Modeling how an agonist activates such a receptor is fundamental for an understanding of a wide variety of physiological processes and it is of tremendous ...

Effect of parenchymal stiffness on canine airway size with lung inflation. [PDF]
PLoS ONE, 2010 Although airway patency is partially maintained by parenchymal tethering, this structural support is often ignored in many discussions of asthma. However, agonists that induce smooth muscle contraction also stiffen the parenchyma, so such parenchymal ...

A normative theory of social conflict [PDF]
arXiv, 2023 Social hierarchy in animal groups carries a crucial adaptive function by reducing conflict and injury while protecting valuable group resources. Social hierarchy is dynamic and can be altered by social conflict, agonistic interactions, and aggression.

Respiratory Research, 2020 Background Activation of free fatty acid receptors (FFAR1 and FFAR4) which are G protein-coupled receptors (GPCRs) with established (patho)physiological roles in a variety of obesity-related disorders, induce human airway smooth muscle (HASM) cell ...

Drug Testing and Analysis, EarlyView.The novel lysergamide 1‐(furan‐2‐carbonyl)‐LSD (1F‐LSD) was analytically characterized. 1F‐LSD showed LSD‐like activity in vivo similar to 1‐(thiophene‐2‐carbonyl)‐LSD (1T‐LSD) used for comparison. Administration studies in mice and LC–MS analysis revealed that 1F‐LSD served as a prodrug.
