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

Adiponectin promotes AMPA receptor trafficking and enhances excitatory synaptic transmission at hippocampal synapses via AMP‐activated protein kinase signalling

British Journal of Pharmacology, EarlyView.
Background and Purpose Peripherally derived adiponectin crosses the blood–brain barrier and targets severa0l brain regions. Adiponectin receptors are highly expressed in the hippocampus, and play a pro‐cognitive role as adiponectin markedly influences the functioning of hippocampal synapses.

SCD2 Alleviates Diabetes‐Associated Cognitive Dysfunction by Improving Microglial Lipid Metabolism

Cell Proliferation, EarlyView.
This study reveals a novel mechanism of microglial metabolic dysfunction in diabetic cognitive impairment. Defective SCD2 disrupts monounsaturated fatty acid (MUFA) metabolism, triggering mitochondrial oxidative phosphorylation dysfunction and leading to abnormal lipid droplet accumulation (marked by PLIN2).

Spatially resolved mapping of histones reveals selective neuronal response in Rett syndrome

The FEBS Journal, EarlyView.
Loss of Mecp2 function is associated with Rett syndrome (RTT). MeCP2 regulates chromatin, yet its influence on histone composition and dynamics is unclear. Combining MALDI‐MSI with LCM–LC–MS/MS, we mapped histone proteoforms across the dentate gyrus, cornu ammonis, and cerebellum in two mouse models of RTT.

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 ...

Orchestrated molecular changes of proliferative, migratory‐fibrillar, synaptic, and postmigratory compartments align with precocious cortex‐type specification in the early human pallium

Journal of Anatomy, EarlyView.
Early human cortical development is organized by transient cellular compartments that define cortical types before mature layers form. Analysis of the human fetal pallium (7.5–15 PCW) shows distinct spatiotemporal trajectories for the archicortex, mesocortex, and neocortex, with delayed but accelerated differentiation in allocortical regions.

The MacBrain Resource Center (MBRC) rhesus macaque postnatal brain histology datasets: Enabling new discoveries through NHP tissue and digital data Repositories

Journal of Anatomy, EarlyView.
The MacBrain Resource Center (MBRC) postnatal rhesus macaque brain histology datasets are organized into Collections that promote cost‐effective de novo research. This article provides examples from Collections 5, 6, and 7 and describes the histo‐ and immunohistochemical (IHC) processing of materials for Collection 6.

Peri‐implantitis and systemic inflammation: Current evidence, biological plausibility, and research gaps

Periodontology 2000, EarlyView.
Abstract Background Peri‐implantitis is a biofilm‐associated inflammatory condition characterized by peri‐implant mucosal inflammation and progressive bone loss. The prevalence of peri‐implantitis continues to rise among patients with dental implants. Although peri‐implantitis and periodontitis share similar inflammatory phenotypes, histopathological ...

Mitochondrial Ca2+ uniporter haploinsufficiency leads to sexually dimorphic redox imbalance and metabolic remodelling in the mouse brain

The Journal of Physiology, EarlyView.
Abstract figure legend The genetic inactivation of one Mcu allele leads to sex‐specific changes in neuronal function in adult mice, that is, the firing of action potentials and the relationship between cytosolic and mitochondrial Ca2+ levels. The ability to produce NAD(P)H by stimulated neural tissue is largely preserved in male mice but delayed in ...
