Probiotic strains have different effects on gut recovery after antibiotics

All probiotics are not created equal, according to new research from North Carolina State University. In a mouse model, researchers found that different probiotic strains can either accelerate or delay the gut microbiome's recovery after antibiotic treatment.

Muscle-derived vesicles heal damaged cells and reverse disease in new study

Researchers discovered that mitochondria-rich extracellular vesicles (Ti-mitoEVs) from skeletal muscle can deliver healthy mitochondria to damaged cells, restoring energy and promoting tissue repair in mice. The approach reversed acute muscle injury and chronic kidney disease, offering a promising new regenerative therapy.

APOE ε4 variant reveals hidden risk factors beyond Alzheimer’s

Researchers discovered that people carrying the APOE ε4 gene variant share a unique immune-related protein signature across their blood, brain, and cerebrospinal fluid—regardless of neurodegenerative disease diagnosis. This signature reveals a fundamental, disease-independent vulnerability linked to APOE ε4, reframing our understanding of genetic risk in conditions like Alzheimer's, Parkinson’s, ALS, and FTD.

Study identifies mechanism that helps prevent cancer, neurodegeneration, and premature aging

Researchers at the University of Oxford and Nanyang Technological University, Singapore (NTU Singapore) have uncovered the mechanism by which cells identify and repair a highly toxic form of DNA damage that causes cancer, neurodegeneration, and premature aging.
