An Anterior Cingulate Cortex‐Anterior Insular Cortex Glutamatergic Circuit Gates Stress‐Induced Visceral Hypersensitivity and Anxiety via Ionotropic Glutamate Receptors Trafficking

Advanced Science, Volume 13, Issue 52, 18 September 2026.
This study identifies an anterior cingulate cortex (ACC) to anterior insular cortex (AIC) glutamatergic (Glu) circuit that gates stress induced visceral hypersensitivity and anxiety. Circuit activation induces both phenotypes, whereas inhibition relieves them.

Palmitoylation of PSD‐95 Orchestrates Learning‐Dependent Metaplasticity in the Amygdala and Fear Memory

Advanced Science, Volume 13, Issue 52, 18 September 2026.
This study reveals that fear learning specifically triggers PICK1/DHHC2‐dependent palmitoylation of PSD‐95 in the lateral amygdala. Fear conditioning induces the dissociation of DHHC5 from PSD‐95 and the association of PSD‐95 with DHHC2. DHHC2‐mediated palmitoylation of PSD‐95 is required for synaptic transmission and underlies fear learning–induced ...

NG2‐Glia in Central Nervous System Following Injury: From Pathological Involvement to Repair Potential

CNS Neuroscience &Therapeutics, Volume 32, Issue 9, September 2026.
Following CNS injury, NG2‐glia display distinct functional phases. In the early stage, NG2‐glia are rapidly activated, proliferate, migrate to the lesion site and secrete CSPGs, which form a chemical and physical barrier that inhibits axonal regeneration.

Anterior Cingulate Cortex Astrocytes Regulate Chronic Itch and Comorbid Negative Emotional Disorders in Mice

CNS Neuroscience &Therapeutics, Volume 32, Issue 9, September 2026.
ACC astrocytes are morphologically and functionally activated in DCP‐induced chronic itch. Chemogenetic activation of these astrocytes positively modulates the calcium activity of local CaMKII+ excitatory neurons and the release of D‐serine and ATP, and exerts anti‐pruritic, anxiolytic, and anti‐depressant effects.

Microglia and neuroinflammation: An in‐depth analysis from functional diversity to disease mechanisms

Clinical and Translational Medicine, Volume 16, Issue 9, September 2026.
1. Microglial functions arise from dynamic, context‐dependent programs rather than fixed M1/M2 phenotypes. 2. Inflammatory, interferon‐responsive, phagocytic/lipid‐metabolic and repair‐associated programs coexist across disease stages and brain regions. 3.
