Exploration of inositol 1,4,5-trisphosphate (IP3) regulated dynamics of N-terminal domain of IP3 receptor reveals early phase molecular events during receptor activation [PDF]

, 2019
Inositol 1, 4, 5-trisphosphate (IP3) binding at the N-terminus (NT) of IP3 receptor (IP3R) allosterically triggers the opening of a Ca2+-conducting pore located similar to 100 angstrom away from the IP3-binding core (IBC).

Differential Dopamine Regulation of Ca2+ Signaling and Its Timing Dependence in the Nucleus Accumbens

Cell Reports, 2016
Dopamine action in the nucleus accumbens (NAc) is thought to drive appetitive behavior and Pavlovian reward learning. However, it remains controversial how dopamine achieves these behavioral effects by regulating medium spiny projection neurons (MSNs) of

The potential for biased signalling in the P2Y receptor family of GPCRs

British Journal of Pharmacology, EarlyView.
The purinergic receptor family is primarily activated by nucleotides, and contains members of both the G protein coupled‐receptor (GPCR) superfamily (P1 and P2Y) and ligand‐gated ion channels (P2X). The P2Y receptors are widely expressed in the human body, and given the ubiquitous nature of nucleotides, purinergic signalling is involved with a plethora

Inositol 1,4,5-Trisphosphate Receptor Type 3 Regulates Neuronal Growth Cone Sensitivity to Guidance Signals

iScience, 2020
Summary: During neurodevelopment, the growth cone deciphers directional information from extracellular guidance cues presented as shallow concentration gradients via signal amplification.

Impact of incretin analogues on lipid and lipoprotein metabolism in obesity and diabetes

British Journal of Pharmacology, EarlyView.
Abstract Incretin‐based therapies have gained momentum as a key strategy for reducing cardiovascular risk in individuals with obesity and/or type 2 diabetes (T2D). It remains unclear whether the cardiovascular benefits reflect a direct reduction in atherogenic lipoproteins—namely, low‐density lipoproteins (LDL), very low‐density lipoproteins (VLDL) and

Arg1 from Cryptococcus neoformans lacks PI3 kinase activity and conveys virulence roles via its IP3-4 kinase activity

mBio
Inositol tris/tetrakis phosphate kinases (IP3-4K) in the human fungal priority pathogens, Cryptococcus neoformans (CnArg1) and Candida albicans (CaIpk2), convey numerous virulence functions, yet it is not known whether the IP3-4K catalytic activity or a ...

The nitty‐gritty of vascular permeability in cancer: targeting blood endothelium to control metastases

British Journal of Pharmacology, EarlyView.
Blood vascular permeability is a hallmark of cancer and acts as an active driver of metastatic dissemination. Metastasis accounts for the vast majority of cancer deaths, yet most work has focussed on tumour‐intrinsic traits and angiogenesis, while the specific contribution of endothelial barrier regulation to intravasation and extravasation remains ...

Models of IP3 and Ca2+ Oscillations: Frequency Encoding and Identification of Underlying Feedbacks [PDF]

, 2006
Hormones that act through the calcium-releasing messenger, inositol 1,4,5-trisphosphate (IP3), cause intracellular calcium oscillations, which have been ascribed to calcium feedbacks on the IP3 receptor.

Bi-allelic variants in RNF170 are associated with hereditary spastic paraplegia

Nature Communications, 2019
Disturbances in IP3 receptor-mediated release of Ca2+ from the endoplasmatic reticulum are associated with neurodegenerative disease. Here, the authors identify in four families with hereditary spastic paraplegia biallelic mutations in RNF170 that ...

Selective excitatory effects of γ‐glutamyl‐glycine, a glutathione metabolite, on GluN1 NMDA and mGlu5 receptors impacting synaptic plasticity

British Journal of Pharmacology, EarlyView.
Background and Purpose Gamma‐glutamyl dipeptides are essentially produced after glutathione (GSH) degradation. While several γ‐glutamyl dipeptides have been detected in different organs and body fluids, their biological activity remains elusive. This is the case for γ‐Glutamyl‐Glycine (γ‐Glu‐Gly) which has been found in different brain areas.
