TCR increases the amount of USP38. 3 / 3
| 3

reach
"Here we found that TCR activation induced expression of ubiquitin-specific peptidase 38 (USP38), whose gene has been recently reported to be in a chromosome locus associated with human asthma in a genome-wide association study (GWAS; Hirota et al., 2011)."

reach
"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."

reach
"178 In the pathogenesis of allergic asthma, TCR signaling can upregulate the levels of the deubiquitinase USP38, which, in turn, stabilizes the TH2 development factor JunB, ultimately promoting asthma."
