Inducible Germline IgMs Bridge Trypanosome Lytic Factor Assembly and Parasite Recognition

Trypanosomiasis is a devastating neglected tropical disease affecting livestock and humans. Humans are susceptible to two Trypanosoma brucei subspecies but protected from other trypanosomes by circulating high-density lipoprotein (HDL) complexes called trypanosome lytic factors (TLFs) 1 and 2. TLFs contain apolipoprotein L-1 contributing to lysis and haptoglobin-related protein (HPR), which can function as a ligand for a parasite receptor. TLF2...
