| Research Abstract |
Phospholipase C・ (PLC・), an intracellular signaling molecule, was implicated in inflammation and tumorigenesis by our study of an experimental skin carcinogenesis model. The aim of this research was to investigate the mechanism of inflammatory reactions mediated by PLC・. This study showed that PLC・ plays an important role in regulation of cytokine production by non-immune cells, such as epidermal keratinocytes and dermal fibroblasts, thereby augmenting inflammation. In addition, keratinocyte-restricted overproduction of PLC・ in mice results in the development of dermatitis accompanied by the characteristic features seen in human psoriasis, such as helper T cell infiltration and the development of silvery adherent scales.
