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, EarlyView.
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

Therapeutic access points: The roles of circumventricular organs in drug delivery and metabolic regulation

British Journal of Pharmacology, EarlyView.
The current obesity drug landscape, dominated by GLP‐1 receptor agonists and emerging multi‐agonist therapies, has reinforced that long‐term weight loss is achieved in large part through central mechanisms that suppress appetite and reshape energy balance.

Chronic silencing of subsets of cortical layer 5 pyramidal neurons has a long‐term influence on the laminar distribution of parvalbumin interneurons and the perineuronal nets

Journal of Anatomy, Volume 246, Issue 4, Page 479-504, April 2025.
Chronic silencing of subsets of layer 5 projection neurons has distinct effects on the laminar distribution of PV interneurons and the perineuronal nets in the adult primary motor and somatosensory cortex. Abstract Neural networks are established throughout cortical development, which require the right ratios of glutamatergic and GABAergic neurons ...

Keratan Sulfate: An Electroconductive Glycosaminoglycan at the Interface of Sensory Perception and Neural Signaling

Journal of Neuroscience Research, Volume 104, Issue 8, August 2026.
Laboratory studies show KS has electroconductive properties with the ability to trap and transport protons in neurotransductive processes (Grotthuss proton shuttling). This maintains electrochemical gradients and fluxes at the neuronal cell surface in neural activation. Such processes are central to neuronal cell signaling and communication.

Characterization of Perineuronal Nets (PNNs) in the Paraventricular Nucleus of the Hypothalamus (PVN) and their alteration in neurogenic hypertension

Abstract Perineuronal nets (PNNs) are key regulators of neuronal excitability, yet whether they are altered during neurogenic hypertension is unknown. Here, we mapped the developmental trajectory of PNNs in the paraventricular nucleus of the hypothalamus (PVN), a crucial nucleus involved in blood pressure regulation, and examined their ...

The Role of Meprins on the Brain Extracellular Matrix and Perineuronal Nets

The FASEB Journal, Volume 40, Issue 13, 15 July 2026.
Meprin β overexpression is implicated in Alzheimer's Disease. Recent studies identified brevican as a meprin β substrate, and this study demonstrates that meprin α co‐expression enhances meprin β‐mediated brevican cleavage. Further, neurocan and RPTPζ were identified as novel meprin β substrates in an N‐terminomics analysis of meprin β transgenic mice,

Dexime: A Selectively Enzyme‐Degradable Hydrogel for Protein Therapeutic Release

Advanced Materials, Volume 38, Issue 38, 8 July 2026.
A dextrin‐oxime hydrogel (dexime) is produced using ketone or aldehyde modified dextrin and tetra‐oxyamine modified poly(ethylene glycol). The rheological and mechanical properties of dexime are tunable. Dexime is injectable, cytocompatible, hydrolytically stable, and selectively degradable by α‐amylase.

Hyaluronan (HA) Receptors: Discovery, Function & Pathology

Proteoglycan Research, Volume 4, Issue 3, July 2026.
ABSTRACT Hyaluronan (HA) is typically a long polymer of the repeating disaccharide, glucuronic acid‐β‐(1‐3)‐N‐acetylglucosamine polymerized by β(1‐4) bonds, with no obvious active site for biological activity. However, this dynamic polymer is vital for life in all metazoans and has a diverse array of functional characteristics due to the proteins that ...

How the forebrain transitions to adulthood: developmental plasticity markers in a long-lived rodent reveal region diversity and the uniqueness of adolescence

Frontiers in Neuroscience
Maturation of the forebrain involves transitions from higher to lower levels of synaptic plasticity. The timecourse of these changes likely differs between regions, with the stabilization of some networks scaffolding the development of others.
