To determine whether the effects of ABA on P. yoelii 17XNL infection were caspase-1-dependent, we examined parasitemia over time and hepatic and splenic gene expression on day 10 PI, when a majority of target mRNA levels were significantly different in ABA-supplemented and unsupplemented C57BL/6 mice (Figs 7A, 8A). The gene discussed is CASP1; the disease is infection.
