Astrocytic TCF7L2 Impacts Brain Osmoregulation and Restricts Neuronal Excitability

open access: yesGlia, Volume 74, Issue 2, February 2026.
Astrocytic TCF7L2 impacts extracellular glutamate and glutamine levels. Loss of astrocytic TCF7L2 disrupts extracellular potassium clearance. TCF7L2‐dependent astrocytic changes reduce neuronal excitability. ABSTRACT Astrocytes differentiate and mature during postnatal development, but the molecular mechanisms linking their maturation to neuronal ...

Junctional conductance of retinal AII amacrine cell electrical synapses is decreased by NMDA receptors

open access: yesThe Journal of Physiology, Volume 604, Issue 3, Page 1373-1390, 1 February 2026.
Abstract figure legend AII amacrine cells are an important class of interneuron in the vertebrate retina. In addition to traditional chemical synapses these cells communicate with other neurons and with each other via electrical synapses. (A) Electrical synapse strength between AII amacrine cells was measured using dual whole‐cell patch‐clamp ...
