Downstream Signaling of Muscarinic M4 Receptors Is Regulated by Receptor Density and Cellular Environment

open access: yesPharmacology Research &Perspectives, Volume 13, Issue 3, June 2025.
ABSTRACT Multiple muscarinic M4 receptor modulators are currently advancing in clinical development for the treatment of positive symptoms in schizophrenia, including agonists and positive allosteric modulators. Considering the importance of comprehending M4 receptor pharmacology for these therapeutic applications, this study investigates M4 receptor ...

Prenatal Exposure to Lipopolysaccharide or Valproate Leads to Abnormal Accumulation of the NMDA Receptor Agonist D‐Aspartate in the Adolescent Rat Brain

open access: yesJournal of Neurochemistry, Volume 169, Issue 6, June 2025.
Autism spectrum disorder (ASD) is a neurodevelopmental condition linked to glutamatergic neurotransmission abnormalities. We analyzed by HPLC the cerebral and peripheral profiles of D‐aspartate, D‐serine, and other L‐amino acids involved in NMDA receptor signaling in environmental ASD rat models prenatally exposed to lipopolysaccharide or valproate ...

The Enteric Neuronal Circuitry: A Key Ignored Player in Nutrient Sensing Along the Gut–Brain Axis

open access: yesThe FASEB Journal, Volume 39, Issue 9, 15 May 2025.
The enteric nervous system (ENS) regulates critical physiological functions including gut motility, blood flow, and epithelial secretions. Despite its autonomous ability to execute local functions, its communication with the central nervous system is integral to the maintenance of homeostasis.

Binding Selectivity Analysis from Alchemical Receptor Hopping and Swapping Free Energy Calculations [PDF]

open access: yesarXiv
We present receptor hopping and receptor swapping free energy estimation protocols based on the Alchemical Transfer Method (ATM) to model the binding selectivity of a set of ligands to two arbitrary receptors. The receptor hopping protocol, where a ligand is alchemically transferred from one receptor to another in one simulation, directly yields the ...
