Notably, it has been documented that T cell growth factor (TCGF, also known as IL‐2) was specifically produced in cutaneous T cell lymphoma H9 cells.21 We speculated that the inhibitory effect of TPD7 on H9 cells may be partially due to IL‐2R pathway. The gene discussed is IL2RA; the disease is primary cutaneous T-cell non-Hodgkin lymphoma.
