Figure 6From: A sensitive flow cytometric methodology for studying the binding of L. chagasito canine peritoneal macrophagesThe levels of CD11b and CD18 fall dramatically following incubation with Leishmania under serum dependent (SD) culture conditions. Peritoneal macrophages were selected based on forward- versus side-scatter parameters as described in Materials and Methods and Figure 1 using flow cytometry. A) Isotype control with macrophages showing delineation of the M1 marker based on the negative population. B and C represent expression of CD18 (B) or CD11b (C) before incubation with Leishmania. D and E represent expression of CD18 (D) or CD11b (E) after association with Leishmania in a SD assay. In all cases the percent positive cells within the M1 marker are identified. This Figure is a representative diagram of 4 experiments with similar findings.Back to article page
