Scientists have discovered that creatine may strengthen one of the immune system's most important cancer-fighting pathways by energizing dendritic cells that activate killer T cells. The promising results could eventually help make immunotherapy more effective, but they have not yet been tested in human patients.

Scientists have identified a molecular switch that may help explain how colorectal cancer becomes deadly. When levels of a gene-regulating factor called GATA6 drop, cancer cells can shed their normal identity and transform into highly adaptable, fetal-like cells capable of spreading through the bloodstream and establishing new tumors in the liver. The study suggests that this dangerous transition is driven less by new genetic mutations and more by changes in how genes are switched on and off.

Researchers discovered an “Achilles’ heel” shared by E. coli, Shigella, and other diarrhea-causing bacteria: enzymes they use to breach the gut’s protective mucus layer. By targeting this common vulnerability, scientists may be able to develop a single vaccine that prevents several major diarrheal infections before they even begin.

A new intranasal DNA vaccine may give the immune system an extra weapon against tuberculosis by targeting bacteria that can hide from antibiotics. In animal studies, it helped clear infections faster, reduced lung inflammation, and prevented relapse after treatment. The vaccine also enhanced the performance of drugs used against drug-resistant TB.
