Research Abstract |
This study focused on the effects of EGF-R pathway on the productivity of chemokines and cytokines in gingival fibroblasts and gingival epithelial cells. We found that inhibition of EGF-R signaling leads to the expression of BAFF, APRIL, and TSLP that is cytokines help to shape the local accumulation and activation of Th2 responses and B cell immunoglobulin production. In addition, EGF-R signaling blockade produces the effect with increased Th2 chemokines, CCL11, CCL17, and CCL26 expression, although no effect with Th1 chemokines, CXCL9, CXCL10, and CXCL11 expression in gingival fibroblasts. These results may imply additional mechanisms by which EGF-R pathway the immune responses in periodontal lesion.
