However, when we accounted for the increase in MAIT cell abundance at baseline by expressing MAIT cell absolute counts for each genotype at day 14 and 70 post infection as a fold-change against the mean baseline count, we found no significant difference between WT and Ripk3−/− mice in MAIT cell expansion or contraction (Fig. 5G), apart from in the lungs and spleen at day 70 where Ripk3−/− MAIT cells exhibited a marginal decrease (in the lungs) and increase (in the spleen) compared to WT (Fig. 5G). The gene discussed is RIPK3; the disease is infection.
