Amyloid‐β aggregates induce vasculopathy via ferroptosis in brain endothelial cells

Brain Pathology, EarlyView.
Blood–brain barrier (BBB) disruption is evident in brains with amyloidopathy. In this study, we demonstrate that amyloid β (Aβ) drives abnormal lipid metabolism and lipid droplet formation in brain endothelial cells, leading to lipid peroxidation and ferroptosis.

Optic nerve sheath meningioma exhibits neural niche‐associated transcriptomic features and rare copy number variation‐linked evolution

Brain Pathology, EarlyView.
Optic nerve sheath meningiomas are typically NF2‐intact with few copy number alterations and are generally clinically indolent. Rare aggressive recurrences are associated with progressive accumulation of copy number variations, including CDKN2A/B homozygous deletion, 1q gain, and 14q loss.

New perspectives on VEGF signalling in Alzheimer's disease

Brain Pathology, EarlyView.
Emery et al. bring together findings from recent multi‐omic studies, including single‐cell mRNA analysis of human post‐mortem brain tissue, and proteomic analysis of matched CSF and blood samples in large clinical studies. The authors present evidence of the involvement of altered VEGF signalling in vascular and immune dysfunction and neurodegeneration

Human brain matters: Navigating the neuropathology of COVID‐19

Brain Pathology, EarlyView.
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

Patient‐derived surgical samples reveal the cellular and molecular signatures of glioblastoma infiltration in distinct radiological zones

Brain Pathology, EarlyView.
Integrated histological and transcriptional profiling of the glioblastoma periphery reveals clinically relevant tumor infiltration beyond MRI‐defined boundaries. MRI‐guided biopsies from contrast‐enhancing (CE), non‐contrast‐enhancing (nCE), edema (E), and radiologically normal (N) regions demonstrate that nCE areas frequently retain neoplastic and ...
