MRC1 and head and neck squamous cell carcinoma: We succeeded in developing such protocols for HNSCC and showed for the first time that HNSCC cells treated with hypofractionated irradiation have a better up-take by M1–MΦ, reduce CD206 on M2–MΦ compared to non-irradiated ones, and that HPV-positive irradiated cells are taken up better by M0g macrophages when compared to HPV-negative cells.
