Fig. 3From: Regulatory and effector T cell subsets in tumor-draining lymph nodes of patients with squamous cell carcinoma of head and neckComparison of the frequencies of CD4+ and its subsets in metastatic (MLNs) and non-metastatic lymph nodes (nMLNs) of patients with HNSCC. CD4+ T cells gated on the lymphocyte population and then the frequencies of T cell subpopulations were determined within CD4+ T cell gate.
