CXCR1 and infection: For that, we determined the expression level of five major neutrophil-targeted chemoattractant receptors (i.e., the chemokine receptors Cxcr1 and Cxcr2, the complement C5a receptor [C5aR], the leukotriene B4 receptor Blt1, and the platelet activating factor receptor [Pafr]), two major neutrophil-targeted chemokines (i.e., the ELR CXC chemokines Cxcl1 [KC] and Cxcl2 [MIP-2]), and five adhesion molecules (i.e., α-integrin X, α-integrin L, β2-integrin, L-selectin and intercellular adhesion molecule 1 [ICAM-1]) in Ccr1+/+ and Ccr1−/− kidneys at days 3, 6 and 9 post-infection.
