FIG 5.

Antigen-presenting cells at the site of infection. Single-cell suspensions derived from skin homogenates from control mice (Nair and PBS) or infected mice isolated at each time point were analyzed to determine the percentage (a) and number (b) of antigen-presenting cells (APCs) (Ly6G⁻ MHC-II⁺ [major histocompatibility complex class II positive] and CD11b⁺ and/or CD11c⁺). Each symbol represents the value for one mouse. The bars represent the means with SEM (n = 5 to 15 mice/group). “#” indicates a P value of <0.05 by a Mann-Whitney test relative to PBS.
