Fig. 7From: Regulatory and effector T cell subsets in tumor-draining lymph nodes of patients with squamous cell carcinoma of head and neckComparison of CD4+ T cells and its subsets in TDLNs of patients with tongue SCC in T1 + T2 and T3 + T4 groups. CD4+ T cells gated on the lymphocyte population and then the frequencies of T cell subpopulations were determined within CD4+ T cell gate.
