Neither T cells from healthy volunteers (Supplementary Fig. 2b), nor any of the lymphoma samples in our cohort (Supplementary Fig. 2c) expressed IL17RC. Accordingly, the levels of TRAF3IP2-regulated transcripts in naive CD4+ T cells transduced with empty pMIG vector (EV), pMIG-TRAF3IP2 or pMIG-FYN-TRAF3IP2 were primarily determined by expression of FYN-TRAF3IP2. Here, CD4 is linked to lymphoma.
