Figure 6A shows that greater numbers of Nfatc2 KO donor T cells than WT T cells were recovered from the spleens, but not from the lymph nodes of adoptive recipients. One interpretation would be that Nfatc2 KO T cells can outgrow WT T cells under conditions of homeostatic expansion. While we cannot formally rule out the possibility that Nfatc2 KO cells simply showed preferential homing to spleen, we believe this is unlikely based the absence of splenomegaly in the Nfatc2 KO B6 mice. This evidence concerns the gene NFATC2 and Splenomegaly.
