演題: Enteric viral infections accelerate aging via STING-dependent NF-kB signaling

講演要旨

The intestinal epithelium plays essential roles in defense against orally acquired pathogens. Homeostasis in this tissue is maintained by constant renewal of differentiated epithelial cells by basal levels of intestinal stem cell (ISC) proliferation and differentiation. I will discuss how persistent viral infection reduces lifespan by driving intestinal dysfunction in a manner involving sustained over-proliferation of ISCs. I will show that enteric viral infection accelerates aging by stimulating prolonged activation of inflammatory Sting-Relish signaling, resulting in dysregulation of classical epithelial repair systems and loss of intestinal homeostasis.  (開催言語:英語 Language: English)
