Fig. 5. FHR is upregulated on the cell surface of forms that are adapted to life in blood ingested by the tsetse fly.

a Western blot analysis probed with FHR antiserum (αFHR) of whole-cell lysates from FHR+/+ and FHR−/− slender BSFs, induced stumpy BSFs, and PCFs in culture and from FHR+/+ stumpy BSFs from a mouse infection. Anti-PFR (αPFR) was used as a loading control. b, c Live-cell-binding assay of 100 nM fluorescent b bovine FH or c FHR-moAb to PCFs in culture. After 2 h, cells were fixed in culture and visualized. Scale bar, 10 μm. d Immunofluorescence analysis of localization of FHR during the majority of the T. brucei life cycle. Cells were collected, fixed and then probed with FHR antiserum. Scale bar, 10 μm. DNA, Hoechst staining of the nuclear and kinetoplastid DNA. Cells positioned with the posterior towards the top right corner. Bars beneath the microscope images represent where complement is present during the life cycle (yellow gradient) and FHR expression (blue gradient). Source data are provided as a Source Data file.
