摘要: The antibacterial defense against infections depends on the cooperation between distinct phagocytes of innate immune system, namely macrophages and neutrophils. However, mechanisms driving this are incompletely understood. In study we describe crosstalk Ly6C+ Ly6C− macrophage-subtypes neutrophils in context urinary tract infection (UTI) with uropathogenic E. coli (UPEC). acted as tissue resident sentinels attracted circulating by chemokines. produced tumor necrosis factor (TNF) that licensed to release preformed CXCL2, which turn caused matrix metalloproteinases (MMP-9) secretion enable transepithelial migration.
