As shown graphically in Figure 2C, at day 9 of infection, these effector CD4+ T cells accounted for approximately 75–80% of the MSP1-specific Tg T cell population, were still a substantial proportion of the total B5 T cell population at day 21, and despite low parasitemias, some even persist to day 60. This evidence concerns the gene ATAD1 and parasitic infectious disease.
