Decreased functionality and expression of trypanosome haptoglobin-hemoglobin receptor (HpHbR) is one of the evolutionary modifications that have allowed Trypanosoma brucei gambiense to infect humans. Here, Horakova et al. show that hemoglobin uptake in African trypanosomes is mediated almost exclusively by HpHbR and relevant for slender-to-stumpy differentiation. T. b. gambiense is poorly competent to differentiate into stumpy forms compared to T. b. brucei, due to reduced functionality of HpHbR.
