Epstein-Barr virus-driven cardiolipin synthesis sustains metabolic remodeling during B cell transformation.

The Epstein-Barr virus (EBV) infects nearly 90% of adults globally and is linked to over 200,000 annual cancer cases. Immunocompromised individuals from conditions such as primary immune disorders, HIV, or posttransplant immunosuppressive therapies are particularly vulnerable because of EBV's transformative capability. EBV remodels B cell metabolism to support energy, biosynthetic precursors, and redox equivalents necessary for transformation.

Myelin is the key structure for high-speed information transmission and is formed by oligodendrocytes (OLs) which are differentiated from oligodendrocyte precursor cells (OPCs) in the central nervous system. Lipid is the main component of myelin and the role of lipid metabolism-related molecules in myelination attach increasing attention. Lysophosphatidylcholine acyltransferase 1 (LPCAT1) mediates the conversion of lysophosphatidylcholine (LPC) to phosphatidylcholine (PC), and its role in myelination draws our interest as LPC is a classical demyelination inducer and PC is a major component of myelin.

P4-ATPases, a subfamily of the P-type ATPase superfamily, play a crucial role in translocating membrane lipids from the exoplasmic/luminal leaflet to the cytoplasmic leaflet. This process generates and regulates transbilayer lipid asymmetry. These enzymes are conserved across all eukaryotes, and the human genome encodes 14 distinct P4-ATPases.

Objective: To study the effect of Dapagliflozin on ferroptosis in rabbits with chronic heart failure and to reveal its possible mechanism.
Methods: Nine healthy adult male New Zealand white rabbits were randomly divided into Sham group (only thorax opening was performed in Sham group, no ascending aorta circumferential ligation was performed), Heart failure group (HF group, ascending aorta circumferential ligation was performed in HF group to establish the animal model of heart failure), and Dapagliflozin group (DAPA group, after the rabbit chronic heart failure model was successfully made in DAPA group). Dapagliflozin was given by force-feeding method.
Mesenchymal stem cells enchanced by salidroside to inhibit ferroptosis and improve premature ovarian insufficiency via Keap1/Nrf2/GPX4 signaling.

Background: Regenerative medicine researches have shown that mesenchymal stem cells (MSCs) may be an effective treatment method for premature ovarian insufficiency (POI). However, the efficacy of MSCs is still limited.
Purpose: This study aims to explain whether salidroside and MSCs combination is a therapeutic strategy to POI and to explore salidroside-enhanced MSCs inhibiting ferroptosis via Keap1/Nrf2/GPX4 signaling.
