FIGURE 1: Phosphatidylthreonine-mediated regulation of calcium signaling and virulence in T. gondii. (A) Scheme illustrating the effect of PTS gene knockout on the parasite. Image is adapted from reference 2. (B) Motile fraction of the indicated parasite strains treated with or without caffeine. Numbers of protein trails (immunostained with anti-Sag1 antibody) formed by extracellular parasites were counted to estimate the motile fraction.
