Additionally, a recent study by Shi et al. found that MAIT cells could migrate from peripheral blood to tumor tissue through the CCR6-CCL20 axis and that tumor-infiltrating MAIT-17s and MAIT-IFNGR phenotypes were associated with the sensitivity of patients with NSCLC to anti-PD-1 immunotherapy [53]. The gene discussed is CCR6; the disease is non-small cell lung carcinoma.
