Figure 4From: CD45RA-Foxp3high but not CD45RA+Foxp3low suppressive T regulatory cells increased in the peripheral circulation of patients with head and neck squamous cell carcinoma and correlated with tumor progressionPercentage of Treg subsets in HNSCC patient subgroups. (A) Flow dot plots of Tregs (Foxp3low and Foxp3high Tregs) (top) and each Treg subset (I: CD45RA+Foxp3low Tregs; II: CD45RA-Foxp3high Tregs; III: CD45RA-Foxp3lowCD4+ T cells) (bottom) for one representative HD and patients with HPSCC, NPSCC, OPSCC, and LSCC. (B) Percentage (means ± SD) of Tregs and each Treg subset in HNSCC patient subgroups or HD. (C) Different proportions (means) of each Treg subset in HNSCC patient subgroups are presented. HD: healthy donors. OCSCC: oral squamous cell carcinoma. HPSCC: hypopharyngeal squamous cell carcinoma. NPSCC: nasopharyngeal squamous cell carcinoma. OPSCC: oropharyngeal squamous cell carcinoma. LSCC: laryngeal squanmous cell carcinoma. Statistical comparisons were performed using the Kruskal–Wallis test.Back to article page
