Abstract
Psoriasis is a T-cell mediated autoimmune disease characterized by increased keratinocyte proliferation. In psoriasis, chemokines are secreted by a wide variety of cells (e.g. keratinocytes, dendritic cells, monocytes), which migrate immune cells (Th17 cells, Th1 cells, neutrophils, etc.) involved in the pathogenesis. Bath-psoralen plus ultraviolet A (PUVA) treatment is an established phototherapy for psoriasis, but its effects on chemokine levels remain unknown. We measured the levels of 22 serum chemokines by using a flow cytometry bead-based immunoassay in 20 psoriasis patients first treated with bath-PUVA therapy between 2007 and 2011 in our hospital.
