Oligodendrocyte Precursor Cells in Demyelination Repair: Mechanisms, Crosstalk, and Therapeutic Frontiers

open access: yesMedicine Bulletin, EarlyView.
ABSTRACT In multiple sclerosis (MS), demyelination is often accompanied by severe motor and cognitive disability. Remyelination is the process of regenerating new myelin sheath on impaired axons, which is typically carried out by oligodendrocyte precursor cells (OPCs).

Cell Apoptosis and Glucocorticoid‐Induced Osteonecrosis

open access: yesMed Research, EarlyView.
The review identifies glucocorticoid‐induced osteocyte/osteoblast apoptosis as central to femoral head osteonecrosis (GION), mediated through STAT1‐caspase‐3, PI3K/Akt, Wnt/β‐catenin, and oxidative stress pathways. Emerging therapies targeting these pathways (e.g., HIF‐1α stabilization, AMPK activation, and exosome‐mediated miRNA delivery) show ...

Proteome Analysis of Corynebacterium diphtheriae–Macrophage Interaction

open access: yesPROTEOMICS, EarlyView.
ABSTRACT Contact of Corynebacterium diphtheriae with macrophages induces adaptations on both bacterial and cellular sides. The study presented here was aiming to shed light on the simultaneous intracellular adaptation of the bacteria and changes in the proteome of the phagocytes in response to the internalization of C. diphtheriae.

Senescence Alters Antimicrobial Peptide Expression and Induces Amyloid‐β Production in Retinal Pigment Epithelial Cells

open access: yesAging Cell, EarlyView.
Healthy RPE cells produce AMPs and AMP precursors, including amyloid precursor protein (APP) and chemerin, and protect the neuroretina from blood‐borne pathogens and maintain homeostasis. When RPE cells undergo senescence, the antibacterial activity declines, and APP undergoes amylogenesis, leading to Aβ deposition.

Langerhans Cell Modulation in Atopic Dermatitis Is TLR2/SOCS1‐Dependent and JAK Inhibitor‐Sensitive

open access: yesAllergy, EarlyView.
Constitutive exposure to TLR2 ligands can modify Langerhans cell (LC) activation capacity and outcome, being similar to LC in atopic dermatitis skin. While maturation marker and migration are impaired, the cytokine profile switches and favors atopic dermatitis‐related IL‐1β and IL‐18.
