چکیده انگلیسی
PlxnB2 and its ligand, CD100, were originally identified as axon-guidance molecules that function during neuronal development; however, studies also showed that CD100-plexins participate in various immune responses. In this study, we found that the expression of PlxnB2 on keratinocytes was specifically increased in lesional skin of psoriasis patients but not atopic dermatitis. Levels of soluble CD100 and membrane-bound CD100 were elevated in sera of psoriasis patients and on keratinocytes of psoriatic skin, respectively. By binding to PlxnB2, soluble CD100 promoted the production of CXCL-1, CCL-20, IL-1β, and IL-18 by keratinocytes and activated the NLRP3 inflammasome. Moreover, CD100-PlxnB2 stimulated the NF-κB signaling pathway in keratinocytes through activation of small GTPase RhoA and Rac1. Our data showed that cooperation of CD100 and PlxnB2 promoted the inflammatory responses in keratinocytes by activating NF-κB and the NLRP3 inflammasome and participated in the pathogenesis of psoriasis. CD100/PlxnB2 might be a potential therapeutic target for psoriasis.
