Figure 2: Kinetics of ear dermis, ear draining lymph nodes and splenic neutrophil recruitment following LdCen−/− intradermal infection.
Mice were injected intradermally either with PBS or LdWT or LdCen−/− parasites for different time periods as indicated. Kinetics of neutrophil recruitment in ear dermis, ear draining lymph node (dLN) and spleen was analyzed by flow cytometry. Neutrophils were defined as a subpopulation of CD11b+myeloid cells having the following markers: Ly6CintLy6G+. Changes in the total number of neutrophils per (A) ear dermis (C) ear dLN and (E) spleen. Values shown are the mean numbers of cells per ear dermis/ear dLN / spleen ± standard deviations of results. 6 ears, ear dLN and spleen at each time point, pooled data from 3 independent experiments (n=6). (*P < 0.05, ** P < 0.005) (B) Changes in the subsets of parasitized (RFP+/ mCherry+) neutrophils in ear dermis at 6h post infection and (D) ear dLN at 48h post infection expressed as a percentage of the total RFP+/ mCherry+ neutrophils. The data presented are means ± SD of 3 independent experiments (n=6).
