Human brain matters: Navigating the neuropathology of COVID‐19

open access: yesBrain 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

Presenting Clinical Features of Vitreoretinal Lymphoma

open access: yesClinical &Experimental Ophthalmology, EarlyView.
ABSTRACT Background Vitreoretinal lymphoma is a rare cancer, widely recognised to present diagnostic challenges. We aimed to report information that would support the clinician in considering this diagnosis. Methods We interrogated the International Vitreoretinal B‐Cell Lymphoma Registry for clinical data from patients newly diagnosed with ...

Age-related increase of kynurenic acid in human cerebrospinal fluid-IgG and beta(2)-microglobulin changes [PDF]

open access: yes, 2005
Kynurenic acid (KYNA) is an endogenous metabolite in the kynurenine pathway of tryptophan degradation and is an antagonist at the glycine site of the N-methyl-D-aspartate as well as at the alpha 7 nicotinic cholinergic receptors. In the brain tissue KYNA

An update on the landscape of collagen bioactive fragments

open access: yesThe FEBS Journal, EarlyView.
The remodeling of the extracellular matrix releases collagen bioactive fragments, which exert molecular functions and regulate numerous biological processes via several signaling pathways. Here, we summarize the latest findings describing the roles of major bioactive fragments from collagens I, IV, VI, and XVIII in various physiological and ...

Variability in intracellular localization of D‐amino acid oxidase in choroid plexus epithelial cells

open access: yesThe FEBS Journal, EarlyView.
D‐amino acid oxidase (DAO) in choroid plexus epithelial cells (CPECs) shows vesicle‐like localization by histological and super‐resolution analyses. DAO colocalizes with peroxisomal, Golgi, endosomal, lysosomal, autophagosomal, and exosomal markers, indicating diverse subcellular distribution. This suggests DAO is transported within CPECs to metabolize

Investigating transthyretin variants H88R and I107V in amyloid priming: From destabilization to complete dissociation

open access: yesThe FEBS Journal, EarlyView.
Investigated mutations in transthyretin (TTR) disrupt the F87‐centered hydrophobic core that stabilizes its tetrameric structure. The mild I107V mutation weakens inter‐chain packing, while H88R fully abolishes tetramer formation, yielding a monomeric, aggregation‐prone form. Structural, biophysical, and computational analyses reveal that both mutations

Proteolytic remodelling of the extracellular matrix by pericytes

open access: yesThe FEBS Journal, EarlyView.
Pericytes are specialised perivascular cells intimately connected with endothelial cells and essential for the maintenance of vascular beds. They contribute to the formation and remodelling of the extracellular matrix by actively secreting proteases and protease inhibitors.
