WebAug 8, 2024 · Mostly, immune evasion by intraerythrocytic parasites is the result of antigenic diversity and sequestration . Intracellular survival also assists the parasite escape by avoiding direct interaction with the immune cells. Lack of MHC-I molecule expression on the surface RBCs also helps parasite to void recognition by CD8 + T cells. WebBy quantifying hemozoin production over the intraerythrocytic cycle, we reveal that hemozoin formation is already initiated by ~ 6–12 h old ring-stage parasites. We demonstrate that the new assay is capable of drug efficacy testing with incubation times as short as 6–10 h, using synchronized P. falciparum 3D7 cultures incubated with …
