Outline of Final Research Achievements

In order to identify novel genes involved in temperature signaling, genetic screening was performed using the phenotype of cold tolerance and acclimation in C. elegans. As a result, several molecules required for cold tolerance were isolated. Among them, the TRPV channels OSM-9 and OCR-2 also functioned as temperature receptors in the novel temperature-sensing neuron ADL. Furthermore, the DEG / ENaC type mechanoreceptor DEG-1 functioned as a temperature receptor in the novel temperature-sensing neuron ASG.

Academic Significance and Societal Importance of the Research Achievements

本研究の線虫C. elegansの低温耐性の解析から、DEG/ENaC型のメカノ受容体(DEG-1)が温度受容体として機能することが初めて見つかった。さらに、DEG-1のヒトホモログであるMDEG2も温度受容体であることが示唆された。今後、MDEG2に対する創薬への期待が高まる可能性がある。TRPVチャネルであるOSM-9/OCR-2複合体が温度受容体として機能していたが、その温度応答性は弱かったため、OSM-9とOCR-2以外の温度受容体の存在が示唆された。
