                                  "We further found that the mRNA level of usp38 did not show statistic difference in different CD4   T cell subsets (Fig. S3 A) and was not induced by the subset-specific cytokines, including IL-2, IL-4, IL-6, IFN, and TGF-β in primary CD4   T cells (Fig. S3 B), suggesting that usp38 expression is directly regulated by TCR signal rather than by cytokines downstream of TCR signaling."
