| Abstract: | 動物は環境温度を鋭敏に感じとり適した温度を選択する，または危険な温度を忌避するなどの行動応答を介し外界の温度変化に能動的に適応する能力を発達させてきた．末梢の感覚神経から入力される温度情報は適切な行動応答に欠かせないことから，様々な種が多様な環境に適応する進化過程で温度受容機構は変化してきたと考えられる．近年，温度受容体を起点とした分子的なアプローチによる種間比較解析が進み，その機能が種間で異なることが明らかとなってきた．本総説では特に，環境適応に関連した温度応答行動，また温度受容体の進化的変化，およびその構造基盤を解明した最新の研究を紹介する． | | Animals evolved the ability to sense and behaviorally respond to changing ambient temperatures. Sensory inputs from peripheral neurons are essential for exerting proper behavioral responses, thus the evolutionary changes of the thermosensory system likely played a fundamental role in the adaptation processes to diverse environments. In recent years, comparative analyses of temperature receptors were performed in various animal species, which revealed the divergence of their functional properties among species. The purpose of this review is to summarize the recent advances in the researches focusing on the evolutionary changes in both behavioral responses and temperature receptors related to the environmental adaptation, as well as the structural basis for the functional changes of temperature receptors. |
