Molecular Mechanisms of L1 and NCAM Adhesion Molecules in Synaptic Pruning, Plasticity, and Stabilization

Frontiers in Cell and Developmental Biology, 2021
Mammalian brain circuits are wired by dynamic formation and remodeling during development to produce a balance of excitatory and inhibitory synapses. Synaptic regulation is mediated by a complex network of proteins including immunoglobulin (Ig)- class ...

Subregion‐specific perineuronal net remodelling in the dorsal hippocampus drives vulnerability and resilience to chronic stress: The role of venlafaxine treatment

British Journal of Pharmacology, Volume 183, Issue 21, Page 6291-6305, November 2026.
Background and Purpose Neuronal plasticity enables the brain to adapt to internal and external demands by dynamically regulating synaptic connectivity and emotional circuitry. Impaired neuroplasticity represents a core pathophysiological framework of major depressive disorder, one of the leading causes of disability worldwide. Chronic stress is a major

How Stress Influences the Dynamic Plasticity of the Brain’s Extracellular Matrix

Frontiers in Cellular Neuroscience, 2022
Diffuse and structured extracellular matrix (ECM) comprise ∼20% of the brain’s volume and play important roles in development and adult plasticity. Perineuronal nets (PNNs), specialized ECM structures that surround certain types of neurons in the brain ...

Hyperacute Interleukin‐1β Production and Neutrophil Extracellular Trap Formation in the Cerebral Circulation of Stroke Patients with Large Vessel Occlusion

Annals of Neurology, Volume 100, Issue 4, Page 824-840, October 2026.
Acute ischemic stroke due to large vessel occlusion is associated with rapid intravascular immune activation. Analysis of arterial blood sampled distal to the thrombus during mechanical thrombectomy revealed increased extracellular adenosine triphosphate (ATP) and interleukin‐1β (IL‐1β) levels, evidence of inflammasome priming in monocytes, and ...

Proteomic Signatures of Noise‐Induced Hearing Loss in the Mouse Cochlea

Cell Biology International, Volume 50, Issue 10, October 2026.
ABSTRACT Hearing loss affects over 1.5 billion people worldwide and has substantial social, educational, and economic consequences. Although genetic studies have identified numerous hearing‐loss‐associated genes, the molecular changes accompanying noise‐induced hearing loss (NIHL) remain incompletely understood.

The Role of Anterior Insular Parvalbumin GABAergic Interneurons in Impulsivity‐Related and Alcohol‐Seeking Behaviors

CNS Neuroscience &Therapeutics, Volume 32, Issue 10, October 2026.
Adolescent impulsivity is linked to increased alcohol seeking and altered activation of anterior insular PV interneurons. Chemogenetic modulation of these neurons regulates inhibitory control and alcohol‐related behaviors, highlighting their role in vulnerability to alcohol use disorder.

The Astrocyte Clock Controls Circadian Perineuronal Net Remodeling, Synapse Strength and Learning Behavior

Glia, Volume 74, Issue 10, October 2026.
Bmal1 regulates astrocyte extracellular matrix (ECM) gene expression. Bmal1 deletion in astrocytes disrupts normal circadian rhythms in perineuronal nets (PNN) and reduces PNN content in the hippocampus. In parallel with loss of PNNs, deletion of the core circadian clock gene Bmal1 in astrocytes alters behavior and synaptic function in vivo.

Shaping Synapses by the Neural Extracellular Matrix

Frontiers in Neuroanatomy, 2018
Accumulating data support the importance of interactions between pre- and postsynaptic neuronal elements with astroglial processes and extracellular matrix (ECM) for formation and plasticity of chemical synapses, and thus validate the concept of a ...

Frozen in Place: Proximity Labeling Maps Glial Interactomes Across Cell States

Glia, Volume 74, Issue 10, October 2026.
Proximity labeling enables cell‐type‐specific and spatially resolved mapping of glial protein networks. Proximity labeling approaches provide insights into glial function under physiological and pathological conditions. ABSTRACT Glial cells, including radial glia, oligodendrocyte precursor cells (OPCs), oligodendrocytes, astrocytes, and microglia, are ...

Harnessing Large‐Scale Multi‐Omics Data for Risk Prediction and Deep Phenotyping of Valvular Heart Diseases in the General Population

Advanced Science, Volume 13, Issue 53, 24 September 2026.
Large‐scale UK Biobank analyses identify clinical and proteomic signatures for early prediction of valvular heart disease and its subtypes. Proteins add predictive value for VHD, AVS, and MVR, with outcome‐specific compact panels showing translational potential. Multi‐layer evidence highlights matrix remodeling, protease regulation, immune inflammation,
