Interleukin 15 induces the signals of epidermal proliferation through ERK and PI 3-kinase in a human epidermal keratinocyte cell line, HaCaT.

Interleukin 15 (IL-15) is a potent stimulator of proliferation and an inhibitor of apoptosis in lymphocytes. We attempted to elucidate the mechanism of IL-15 function in HaCaT keratinocytes. We found that 5-bromo-2(')-deoxyuridine incorporation increased in a dose-dependent manner with IL-15. This was blocked by MEK inhibitor U0126 or PI 3-K inhibitor LY294002. ERK1/2 and Akt phosphorylation by IL-15 were detected in a dose- and time-dependent manner. U0126 and LY294002 abolished ERK1/2 and Akt phosphorylation, respectively. DNA fragmentation and Annexin V binding accompanied by UVB- induced apoptosis were reduced by 30-50% with IL-15. Taken together, IL-15 induced cellular proliferation and had an anti-apoptotic effect on keratinocytes, in which ERK1/2 and Akt phosphorylation played crucial roles. The signal transduction pathways of IL-15 in keratinocytes were partially elucidated; they share a substantial part with growth signals induced by EGF. These results suggest a therapeutic approach to inflammatory skin diseases by controlling these signals.[1]
