Abstract
Objective:To investigate the role of CD4 ⁺ CD25 ⁺ T regs and CCL17 and CCL22 in the pathogenesis of HNSCC.Method:Twenty cases of HNSCC were enrolled. All patients were primary or recurrent after treatment (chemotherapy, surgery). The primary tumor was taken as the experimental group, and the adjacent normal tissues from the primary tumor 1-3 cm were taken as control group. CD4 ⁺ /Foxp3 and CD25⁺/Foxp3 were detected by immunofluorescence, while CCL17 and CCL22 were detected by ELISA. The difference and correlation between the amount of CD4⁺,CD25⁺ and the expression of CCL17, CCL22 were observed and analyzed.Result:The difference of mean optical density between CD4⁺/Foxp3 and CD25⁺/Foxp3 was statistically significant between the experimental group and the control group (P<0.05). The concentration of CCL17 and CCL22 was statistically different between the two groups (P<0.01). There was a positive correlation between CD25⁺and CCL17,CCL22(r=0.595, 0.720,P<0.01).Conclusion:CD4⁺CD25⁺T regs and CCL17,CCL22 played an important role in the pathogenesis of head and neck squamous cell carcinoma,both of which interacted with each other,and promoted the recurrence and metastasis of HNSCC.
