Figure 1From: Cellular responses to modified Plasmodium falciparum MSP119 antigens in individuals previously exposed to natural malaria infectionMean T cell responses in malaria-exposed and un-exposed individuals. Responses to the wildtype-MSP119, modified MSP119 antigens, PHA, GST and F32 (a crude malarial antigen preparation) in seven malaria-exposed individuals (shaded boxes) and five unexposed malaria-naïve individuals (open boxes), as measured by stimulation index (SI). The malaria-exposed individuals showed significantly higher responses to all the malaria antigens than the malaria-unexposed individuals (P = 0.001).Back to article page
