Prof. Kawauchi presented “Conditional expression and activation of DREADDs reveals novel impact of neuron-tumor communications on brain tumor progression” at Neuro2024 (Fukuoka). This is a collaborative study with Prof. Naofumi Uesaka from Tokyo Medical and Dental University, focusing on elucidating the relationship between brain tumors and neural activity. Now, the fields of brain tumors and neuroscience should be integrated, requiring more multifaceted analysis. On the other hand, such unique research is expected to reveal new mechanisms of tumor progression!
