CD8A and malaria: Our current understanding of CD8+ T‐cell responses to malaria pre‐erythrocytic stages has been largely based on measuring responses to the H‐2‐Kd‐restricted epitopes of rodent P. yoelii (Py) (Weiss et al,1990) and P. berghei (Pb) (Romero et al,1989) circumsporozoite proteins (CSP), the major surface antigen of sporozoites.
