Metformin, EDH, and Mesenteric Perfusion in Colitis
2026-08-07
A 2025 European Journal of Pharmacology study identifies a direct vascular action of metformin in mesenteric resistance vessels, linking endothelial calcium signaling and endothelium-dependent hyperpolarization to protection of the colonic mucosa in murine colitis. Its combination of human and mouse arteriole studies, endothelial-cell electrophysiology, TRPV4 genetics, and a DSS disease model provides a mechanistic framework for evaluating metformin as a potential colitis therapy, while leaving clinical translation unresolved.

Norovirus Hijacks NINJ1 for Selective Protein Secretion
2026-08-06
Song et al. uncover how murine norovirus (MNoV) strategically co-opts the host protein NINJ1 to enable selective secretion of its NS1 protein during infection, revealing a new paradigm for unconventional protein export via regulated cell death. These findings have broad implications for understanding virus-host interactions, cell death regulation, and selective cargo release.
