Fig. 6From: Regulatory and effector T cell subsets in tumor-draining lymph nodes of patients with squamous cell carcinoma of head and neckComparison of CD8+ T cells and its subsets in TDLNs of HNSCC patients in low stages (I + II) and advanced stages (III + IV) of the disease. CD8+ T cells gated on the lymphocyte population and then the frequencies of T cell subpopulations were determined within CD8+ T cell gate. Horizontal bar is representative of the Mean ± SEM, *P value < 0.05, **P value < 0.01Back to article page
