CCR1 and Candidiasis, Invasive: Because Ccr1 is expressed on neutrophils and monocytes/macrophages [22], which are critical for survival after invasive candidiasis, and since Ccr1 and its ligands were induced in the model, we investigated the in vivo role of Ccr1 in the pathogenesis of invasive candidiasis using Ccr1−/− mice.
