FIG. 11.
The effect of systemically administered antisera against CXCR2 on neutrophil migration to the site of Ehrlichia inoculation. Two groups of three BALB/c mice were i.p. injected with antisera to CXCR2 or control sera prior to i.p. Ehrlichia inoculation. Four hours later, peritoneal lavage fluids from these mice were analyzed by flow cytometry by using fluorescein isothiocyanate-labeled antibodies to Gr-1 molecule. Peritoneal lavage neutrophil counts for these mice were compared with counts for those that did not receive antisera or bacteria and those that received only Ehrlichia sp. Results from one of two representative studies are shown.
