| abstractText | MicroRNAs (miRNAs) play very important roles in the control of immune cell and keratinocyte development and function and are implicated in skin inflammatory diseases, including psoriasis. miRNA miR-17-92 was reported to promote the differentiation of Th1 and Th1 cells and to regulate cell proliferation and apoptosis. Here we showed that imiquimod (IMQ) differentially regulates the expression of miR-17-92 cluster in the mouse skin, upregulating miR-17 and miR-19 families and downregulating miR-92. To investigate whether miR-17-92 cluster is functionally involved in the psoriasis, we have generated three mutant mice with specific deletion or overexpression of miR-17-92 cluster in keratinocytes, or with deletion of miR-17-92 cluster in T cells. Interestingly, deletion or overexpression of miR-17-92 cluster in keratinocytes, or deletion of miR-17-92 in T cells did not significantly affect IMQ-induced psoriasis-like dermatitis development in the mutant mice compared with wild-type littermates. Thus, miRNA miR-17-92 cluster may not be a key factor regulating imiqumod-induced psoriasis-like dermatitis. |
