Figure 1From: 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 112 HNSCC patients. (A) Gating strategy used is illustrated. (B) Flow dot plots of Foxp3+CD25+ Tregs for one representative HD (left) and HNSCC patient (middle). Percentage (means ± SD) of Foxp3+CD25+ Tregs in HNSCC patients or HD (right). (C) Flow dot plots of each Treg subset (I: CD45RA+Foxp3low Tregs; II: CD45RA-Foxp3high Tregs; III: CD45RA-Foxp3lowCD4+ T cells) for one representative HD (left) and HNSCC patient (right). (D) Percentage (means ± SD) of each Treg subset in HNSCC patients or HD. HNSCC: head and neck squamous cell carcinoma. HD: healthy donors. Statistical comparisons were performed using the Mann–Whitney U-test.Back to article page
