The data in Fig. 2C show that helminth infected mice had significantly higher levels of circulating IL-10 at the time of the initiation of malaria infection compared to mice without helminth infection (H. polygyrus infected: 0.508 ± 0.077 ng/ml; uninfected: 0.047 ± 0.003 ng/ml, p < 0.005). The gene discussed is IL10; the disease is helminthiasis.
