IL2 and cervical carcinoma: We have previously demonstrated that low doses of IL-2 (10 IU/mL) increased the proliferation of cervical cancer cells [23,24], and with high doses of IL-2 (100 IU/mL), the proliferation decreased [21]; as expected, 10 IU/mL of IL-2 induced a significant increase in proliferation on both cell lines (Figure 1C), and 100 UI/mL decreased proliferation, which indicates that this response to IL-2 is maintained regardless of the type of HPV.
