辣椒素受体在皮肤淀粉样变中的表达
[Abstract]:Objective to investigate the expression of capsaicin receptor (TRPV1) in skin amyloidosis and its role in cutaneous amyloidosis. Methods 22 cases of skin amyloid lesions and 16 cases of normal skin tissues were selected to study the expression of capsaicin receptor by semi-quantitative RT-PCR and immunohistochemistry. Results the expression level of TRPV1 gene in skin amyloidosis lesions was significantly higher than that in normal skin (P0.05). Immunohistochemical study showed that TRPV1 was found in normal skin, epidermal keratinocytes with amyloidosis, and epidermal keratinocytes (hair follicles). Sebaceous gland and sweat gland) and vascular endothelial cells were expressed. The expression of TRPV1 in skin amyloidosis was higher than that in normal skin (P0.05). Conclusion the expression of TRPV1 in skin amyloidosis is higher than that in normal skin, suggesting that TRPV1 may play a role in the occurrence and development of skin amyloidosis induced pruritus.
