CD8A and malaria: Given the scarcity of protective CD8 epitopes, another convenient way to study CD8+ T cell responses against infected hepatocytes is to use the epitope of ovalbumin (OVA) fused to endogenous and exogenous antigens expressed in malaria PE stages (Cockburn et al., 2011; Kimura et al., 2013; Montagna et al., 2014).
