}African trypanosomes cause disease in humans and animals. Trypanosoma brucei brucei affects cattle but not humans because of its sensitivity to a subclass of human high density lipoproteins (HDLs) called trypanosome lytic factor (TLF). TLF contains two apolipoproteins that are sufficient to cause lysis of T. b. brucei in vitro. These proteins were identified as the human haptoglobin-related protein and paraoxonase-arylesterase. An antibody to haptoglobin inhibited TLF activity. TLF was shown to…

Low temperature binding studies reveal two receptors for TLF-1: one that is high affinity/low capacity and another that binds with low affinity/high capacity, and it is proposed that Hpr mediates the high affinity binding of TLf-1 toT.
