Expression of Th1/Th2 Cytokines in Patients with Cutaneous Nodular Vasculitis / 中华皮肤科杂志

ABSTRACT

Objective To investigate the relationship between CD3+T, CD4+T, CD8+T cells, Th1/Th2 cytokines IL-2, IL-4, IL-6, sIL-2R and the pathogenesis as well as disease activity in patients with cutaneous nodular vasculitis (NV). Methods Cytokines IL-2, IL-6, sIL-2R and cell surface markers CD3+, CD4+ and CD8+ were detected by flow cytometry and ELISA with peripheral blood mononuclear cells from patients and controls. Expressions of IL-2, IL-4 and CD3+, CD4+, CD8+ were determined by immunohistochemistry in patients′ lesions in situ. Results Serum levels of IL-2, IL-6 and sIL-2R were significantly increased in patients with active NV compared with those in inactive stage(P
