For example, Mindiola et al. demonstrated that the expression of IL-2, IL-2R, and IL-10 in cervical tissue may play a role in the development of cervical intraepithelial dysplasia [68], whereas the expression of IL-2 is associated with cell proliferation in cases of squamous cell carcinomas of the head and neck (SCCHN) [69]. This evidence concerns the gene IL2 and head and neck squamous cell carcinoma.
