The proportion and the number of Gr-1+CD45+ cells were significantly lower (p < 0.05) in mice treated with anti-KC antibody compared to the corresponding control mice at early infection (7 dpi) and during the onset of disease (21 dpi), but higher (p < 0.05) after the development of disease at 38 dpi (Figures 5A,B). This evidence concerns the gene PTPRC and infection.
