| Outline of Final Research Achievements |
Animals cope with environmental stimuli through its own behavioral plasticity. In this study, I investigated the mechanism underlying the behavioral plasticity in C. elegans. I first found that an activity of a MAP kinase oscillates in vivo. Therefore, I analyzed this oscillation using biochemical and imaging techniques. As a result, I showed that the oscillation of MAP kinase activity underlies plasticity of C. elegans mechanosensory behavior. I further analyzed the coding and decoding mechanism of the oscillation during establishment of behavioral plasticity. I summarized these results and am now submitting manuscript in a journal.

p38は別名ストレス応答性キナーゼと呼ばれ, ストレス応答を制御するマスターレギュレーターである. 本研究で注目した力学刺激は１つの物理的ストレスともみなすことができ, その処理機構の一端を示したこととも同義である. 現在, 他のストレス刺激下における動的変化の時間パターンの違いからのストレス刺激識別機構の解明しつつある.
