Type 1 piliated uropathogenic Escherichia coli hijack the host immune response by binding to CD14

Kathrin Tomasek

A key attribute of persistent or recurring bacterial infections is the ability of the pathogen to evade the host's immune response. Many Enterobacteriaceae express type 1 pili, a pre-adapted virulence trait, to invade host epithelial cells and establish pe ...
