Cross-presentation of a human malaria CTL epitope is conformation dependent.


Little is known about the role of conformation on the antigen processing by antigen presenting cells. Using a well-defined antigen containing two disulfide bridges, the synthetic C-terminal fragment 282-383 derived from Plasmodium falciparum circumsporozoite protein (PfCS 282-383), we show that the reduced form is presented in vitro more efficiently than… (More)
