Enteropathogenic E. coli-mediated Fast and Coordinated Ca2+ responses regulate NF-κB activation

Fangrui Guo, Roberto Ornelas Guevara, Linda Oussaedine…·Guy Tran Van Nhieu

This study shows EPEC induces fast, coordinated Ca2+ responses via eATP, leading to reduced NF-κB activation through dampened O-linked β-N-acetylglucosamine modification.
