Description

Christopher J Schwake and co-authors report, in 2026, a shared antibody target between two malaria parasite proteins on infected red blood cells. Malaria from Plasmodium falciparum kills many children in sub-Saharan Africa. Infected cells stick to blood vessel walls using knob-like bumps, which can cause severe brain and pregnancy disease.

The team made an antibody, GM7, against one knob protein, PfGARP. Using protein scans and parasite lines missing PfGARP, they found the antibody also fits a second protein, PIESP2. Part of PIESP2 sits on the knob surface. The antibody also detected immune responses to PIESP2 in people from a region where malaria is common, opening a new angle on how knobs help infected cells stick.
