细胞因子胸腺基质淋巴细胞生成素(TSLP)最近被牵连在特应性皮炎(AD)和其他过敏性疾病的发病机制在人类。为了进一步表征其在该疾病过程中的作用,产生表达角质形成细胞特异性四环素诱导型TSLP转基因的转基因小鼠。TSLP的皮肤特异性过表达导致AD样表型,伴随含有炎性真皮细胞浸润的湿疹性病变的发展,表达皮肤归巢受体的Th2 CD4+ T细胞急剧增加,以及血清IgE水平升高。这些转基因小鼠证明TSLP可以在皮肤中引发一系列过敏性炎症,并为这种常见疾病的未来研究提供了有价值的动物模型。
The cytokine thymic stromal lymphopoietin (TSLP) has recently been implicated in the pathogenesis of atopic dermatitis (AD) and other allergic diseases in humans. To further characterize its role in this disease process, transgenic mice were generated that express a keratinocyte-specific, tetracycline-inducible TSLP transgene. Skin-specific overexpression of TSLP resulted in an AD-like phenotype, with the development of eczematous lesions containing inflammatory dermal cellular infiltrates, a dramatic increase in Th2 CD4+ T cells expressing cutaneous homing receptors, and elevated serum levels of IgE. These transgenic mice demonstrate that TSLP can initiate a cascade of allergic inflammation in the skin and provide a valuable animal model for future study of this common disease.
