ITGAM and infection: We next determined the frequency of pan CD45high leukocytes, CD45highLy6C+Ly6G−F4/80+CD11b+CD11c− inflammatory monocytes, CD45highCD11b+F4/80−Ly6GhiLy6Cmed neutrophils, and CD3+CD4+ T cells infiltrating the inflamed cornea at day 2 and day 8 post-infection with virulent vs. less-virulent laboratory strains and clinical isolates of HSV-1.
