In contrast, there were no differences in T and B cell populations in the spleen and lymph nodes between Mir223 knockout lupus-prone MRL-Mir223−/−Faslpr/lpr and MRL-Mir223+/+Faslpr/lpr mice (Supplementary Figure 3E and Supplementary Figure 5E). This evidence concerns the gene MIR223 and systemic lupus erythematosus.
