Аннотация
To investigate the role of Interleukin-17 (IL-17), Interferon-gamma (IFN-gamma), and macrophage inflammatory protein-3 alpha (MIP-3alpha) in the pathogenesis of psoriasis, reverse transcriptase-polymerase chain reaction (RT-PCR) was used to semi-quantitatively analyze the mRNA expression of IL-17, IFN-gamma, and MIP-3alpha in 31 psoriatic lesions and 16 normal skin tissues. The results showed that the mRNA of the three cytokines was present in all specimens. And the expression level of IL-17 mRNA in skin lesions was 1.1416 +/- 0.0591, which was significantly higher than that in normal controls (0.8788 +/- 0.0344, P<0.001). The expression levels of IFN-gamma mRNA were 1.1142 +/- 0.0561 and 0. 9050 +/- 0.0263, respectively, with significant difference (P<0.001). And the expression levels of MIP-3alpha mRNA in psoriatic lesions was 1.1397 +/- 0.0521, which was markedly higher than that in normal controls (0.8681 +/- 0.0308, P<0.001). These findings indicate that up-regulated expression of IL-17, IFN-gamma, and MIP-3alpha might be involved in the pathogenesis of psoriasis.
