RESUMO

Objective:To examine the plasma soluble interleukin 2 receptor (sIL-2R)and the expression of IFN-γR in helper T (Th)cells in peripheral blood of patients with recurrent oral ulcer(ROU).Methods:The peripheral blood was obtained from 21 pa-tients in active stage of ROU and 21 healthy controls.Flow cytometry was used to detect the quantity of IFN-γR in CD +4 T cells,ELISA was used to detect the level of sIL-2R.Results:The expression of IFN-γR in CD +4 T cells and sIL-2R content in plasma of the patients with ROU were significantly higher than those in the healthy controls(P <0.05).Conclusion:Over expression of IFN-γR in CD +4 T cells and sIL-2R in peripheral blood may be related to the genesis of ROU.

RESUMO

Objective:To investigate the expression of LAIR-1 on Treg cells and TGF-βin the peripheral blood of patients with oral lichen planus(OLP).Methods:The peripheral blood was obtained from 22 OLP patients and 22 healthy controls.Flow cytometry was used to evaluate the proportion of LAIR-1 on CD4 +Foxp3 +Treg cells,and the level of TGF-βwas measured by ELISA.Results:In the peripheral blood of OLP patients,the proportion of LAIR-1 on CD4 +Foxp3 +Treg cells and TGF-βcontent were significantly higher than those of the healthy controls(P <0.05),The proportion of LAIR-1 on CD4 +Foxp3 +Treg cells was positively correlated with the level of TGF-β(r =0.43,P <0.05).Conclusion:The high expression of LAIR-1 on CD4 +Foxp3 +Treg cells and TGF-βin the pe-ripheral blood of OLP patients may be responsible for the pathogenesis of OLP.
