BACKGROUND: Toll-like receptor (TLR) 2 belongs to the large TLR receptor family comprised of at least 10 members with different roles in innate immunity. Psoriasis is recognized as a T-cell driven immune-mediated systemic inflammatory disease with a skin manifestation. An effective therapeutic approach to treat psoriasis is Goeckerman therapy (GT). The aim of this study was to assess both the kinetics of the expression of TLR2 on blood cells and the concentration of soluble (s)TLR2 in serum of patients with psoriasis and to examine the effect of GT on both TLR2 expression and sTLR2 level. METHODS: Both membrane and sTLR2 were determined in 20 patients and 20 healthy controls. sTLR2 was evaluated by enzyme-linked immunosorbent assay. Flow cytometry method was used to determine the expression of membrane TLR2 of monocytes and granulocytes. RESULTS: The serum level of sTLR2 was significantly lower (P < 0.0001) in patients both before and after GT compared to the control group. Compared to the membrane expression of TLR2 on monocytes of healthy blood donors, TLR2 expression was significantly higher in patients both before and after GT (P = 0.0001). Similarly, TLR2 expression on granulocytes was significantly higher in patients both before (P = 0.0061) and after (P < 0.0001) therapy than in control. CONCLUSIONS: Membrane and soluble TLR2 may be involved in the pathogenesis of psoriasis. Both remained unchanged by GT.
