Abstract:
AIM:To observe the effects of Liangxue-Jiedu (LXJD) prescription, a Chinese medicine, on the expression of CC chemokine ligand 20 ( CCL20 ) and CC chemokine receptor 6 ( CCR6 ) in imiquimod-induced psoriasis-like skin lesions in a mouse model .METHODS: Male BALB/c mice were randomly divided into control group , model group, LXJD treatment group and chemokine CCL 20 monoclonal antibody treatment group .The mouse model of psoriasis was induced by imiquimod .The severity of psoriasis was assessed by the dermatologists using psoriasis area and severity in -dex (PASI).The morphological changes of the skin tissues were observed under light microscope .The thickness of epider-mis was measured .Real-time PCR was used to detect the expression of CCL 20 and CCR6 in the skin tissue samples .RE-SULTS:The skin in model group showed a large number of scales , erythema and skin thickening .Compared with model group, the skin lesion in LXJD treatment group was attenuated .The erythema and scales were alleviated , the PASI score was reduced , and the expression of CCL 20 and CCR6 was significantly lower than that in model group .CONCLUSION:LXJD prescription down-regulates the expression of CCL 20/CCR6, thus attenuating the psoriasis skin lesions in mice .
