IL2RG and neoplasm: In this context, our results show the presence of the different subunits of the IL-2 receptor (IL-2Rα, IL-2Rβ, and IL-2Rγ) in HPV18+ cell lines, derived from cervical tumour tissue (Figure 1) and the response of these tumour cells to the administration of high doses of IL-2 (100 IU/mL).
