Outline of Final Research Achievements |
Malignant melanoma is the tumor of poor prognosis and being characterized by a melanogenic property. Though it has been recently revealed important to derepress the function of anti-tumor cytotoxic t cells, the relationship between melanogenesis and the immune-suppression of cytotoxic t cells remains unknown. We revealed that one of the metabolites of melanogenesis activates aryl hydrocarbon receptor of cytotoxic t cells besides malignant melanoma that leads to the suppression of cytotoxic t cells.

Academic Significance and Societal Importance of the Research Achievements |
本研究は悪性黒色腫に特異的なメラニン色素合成系と同腫瘍の病態に重要な細胞障害性T細胞の関係を解明したものである。このことはAryl hydrocarbon receptor活性の調整が、既存の治療薬と比較して悪性黒色腫に対してより特異的(副作用が少なく)かつ治療効果は劣らない加療法の開発につながる可能性を示唆している。
