[Effect of interleukin-6 on gene expression of certain cytokines during wound healing process of mouse skin].

To examine the effect of the interlukin-6 (IL-6) in wound healing process, gene expression profiles of cytokines including interlukin-1alpha (IL-1alpha), interlukin-1beta (IL-1beta), keratinocyte chemoattractant (KC), macrophage inflammatory protein-1alpha (MIP-1alpha), and macrophage inflammatory protein-2 (MIP-2) during the skin wound healing on the IL-6(+/+) and IL-6(-/-) mice were detected using immunochemical staining and RT-PCR methods at different phases after wound. The results showed that these cytokines were expressed at early phage after wound, and a expressing peak were found on the third day after wound, and decreased on the sixth day after wound. Meanwhile, on the third and sixth day after wound, all the levels of the five cytokines expressed of the IL6(-/-) mice were significantly lower than those of the IL-6(+/+) mice, but on the first day after wound, only the levels of MIP-1alpha and KC of the IL-6(-/-) mice were lower.
