Confirming previous observations by Degrandiet al. (Degrandiet al., 2007), we found the induction of Gbp2b and Gbp2 mRNA expression in the spleens of mice at 8 days post infection to occur only with liveToxoplasma but not with heat-killed (HK) parasites (Figure 2A and B, underlying data (Cloughet al., 2019)). The gene discussed is GBP2; the disease is infection.
