Cytokine profile from the R. parkeri intradermal inoculation site as determined by reverse transcriptase qPCR. Itgax (CD11c, a histiocytic cell marker), Mcp1 (monocyte chemotactic protein 1, a chemokine for histiocytic cells), and Il1β (produced by activated macrophages) were assessed to determine histiocytic cell activation, and results showed no significant difference among groups. Data presented as mean ± SEM.
