Human brain matters: Navigating the neuropathology of COVID‐19

Brain Pathology, Volume 36, Issue 6, November 2026.
Severe COVID‐19 is associated with vascular dysregulation and chronic neuroinflammation, leading to axonal injury and neurodegeneration. In long COVID or PASC, persistent alterations in neuroimaging and biofluid biomarkers reflect ongoing neuronal damage and neuroinflammation, contributing to long‐term neurological symptoms including fatigue, cognitive

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

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

British Journal of Pharmacology, Volume 183, Issue 21, Page 6501-6518, November 2026.
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.

Functional Imaging of Hippocampal Layers Using VASO and BOLD on the Next Generation (NexGen) 7T Scanner

Human Brain Mapping, Volume 47, Issue 15, October 15, 2026.
CBV VASO based fMRI was optimized on NexGen 7T for layer‐specific hippocampal imaging and tested using an autobiographical memory task. Depth dependent activation profiles based on VASO and BOLD images from the same acquisition differed particularly in subiculum, consistent with activation mislocalization in BOLD profiles due to venous bias.

RPLP2 Mediates the Beneficial Effects of Exercise on Stress Resistance Through Muscle–Brain Communication

Advanced Science, Volume 13, Issue 55, 5 October 2026.
A novel exercise‐inducible myokine acidic ribosomal protein P2 (RPLP2), initially identified from human trials, is presented here, whose circulating levels negatively correlate with clinical anxiety severity. Muscle‐derived RPLP2 enhances hippocampal ribosomal assembly and adult neurogenesis to rescue stress‐induced anxiety deficits.

Targeted β‐Glucan‐Veiled Oral Apremilast Nanotherapy Modulates Key Dysbiosis‐Associated Gut Microbiota and Alleviates Ulcerative Colitis‐Associated Anxiety, Depression, and Neuropsychiatric Behaviors

Advanced Science, Volume 13, Issue 55, 5 October 2026.
This study introduces β‐glucan‐shielded apremilast laden nanomicelles that withstand gastrointestinal degradation, selectively accumulate in inflamed colon tissue, and modulate the microbiota–gut–brain axis. The formulation restores barrier integrity, reduces systemic and neuroinflammation, and improves anxiety‐ and depression‐like behaviors in colitis

Enhancing Super‐Resolution Spatial Transcriptomics Data by Transfer Learning

Advanced Science, Volume 13, Issue 56, 9 October 2026.
SpotZoomer employs a transfer‐learning‐based strategy to enhance the resolution of Visium data by leveraging available high‐resolution priors. The resulting super‐resolved maps enable sharper delineation of cell boundaries and more precise inference of cell–cell communication patterns that would otherwise remain obscured at native resolution.

Structural Polymorphism of polyG Inclusions Revealed by In Situ Cryo‐Electron Tomography

Advanced Science, Volume 13, Issue 56, 9 October 2026.
Correlative cryo‐electron tomography in primary cortical neurons and NIID mouse brain tissue reveals that polyG inclusions are interconnected ribbon‐like assemblies rather than canonical amyloid fibrils. Multiple compartment‐specific ribbon states show distinct 26S proteasome accessibility, while cytoplasmic ribbons contact and deform ER‐like ...

Polydopamine Nanoparticle‐Mediated Precise Near‐Infrared Optical Stimulation for Cognitive Enhancement

Advanced Science, Volume 13, Issue 56, 9 October 2026.
Polydopamine nanoparticles enable a precise, non‐genetic, and transcranial neuromodulation strategy via near‐infrared photothermal stimulation. By activating TRPV1 channels, this approach specifically enhances hippocampal gamma oscillations, thereby rescuing spatial memory deficits in models of perioperative neurocognitive disorder.
