Variant antigen diversity in Trypanosoma vivax is not driven by recombination [PDF]

Nature Communications, 2020
Trypanosoma rely on variant surface glycoprotein (VSG) to escape host immunity, but mechanisms generating antigenic diversity of VSG are poorly understood. Here, Silva-Pereira et al. show that T.

Investigation ofTrypanosoma-induced vascular damage sheds insights intoTrypanosoma vivaxsequestration [PDF]

The Cell Surface, 2023
AbstractMultiple blood-borne pathogens infecting mammals establish close interactions with the host vascular endothelium as part of their life cycles. In this work, we investigate differences in the interactions of threeTrypanosomaspecies:T. brucei, T. congolenseandT. vivaxwith the blood vasculature.
