Increased expression of Th2-associated chemokines in bullous pemphigoid disease. Role of eosinophils in the production and release of these chemokines
چکیده انگلیسی

Bullous pemphigoid is an inflammatory disease of the skin associated with eosinophil infiltration and the presence of high levels of Th2 cytokines in the associated blister fluid. Little is known about the contribution of chemokines in this disease. We found that eotaxin and MCP-4 mRNA and immunoreactivity were expressed in all biopsies of BP patients and were mainly localized to the epidermis and eosinophils. The expression of eotaxin and MCP-4 was enhanced in eosinophils following IL-5 treatment. Subsequent stimulation of IL-5-primed eosinophils with Ig-immune complexes, results in increase secretion of eotaxin and MCP-4 in the supernatants. Using immunostaining, these two chemokines were localized to the granules of eosinophils. BF was found to contain chemotactic activity for eosinophils, neutrophils and T cells. The chemotactic effect of BF for eosinophils was more effective when eosinophils were stimulated with IL-5 or IL-4. We also found that the levels of Th2-associated chemokines (eotaxin and MCP-4) in BF were significantly higher than the Th1-associated chemokines (MIP-1β and IP-10). This was consistent with the increased chemotaxis of polarized Th2 cells toward BF, when compared to Th1-differentiated T cells. Our results support the involvement of Th2-associated chemokines in the pathogenesis of BP disease.
