Professor Youngseok Lee attended the 2026 4th China-Korea-Japan (CKJ) Drosophila Conference, held from August 14–16, 2026, in Harbin, China. The conference, themed “The Power of Drosophila Genetics,” brought together Drosophila researchers from China, Korea, and Japan to promote scientific exchange and international collaboration.

During the Reproductive and Sensory Systems session on August 15, Professor Lee delivered a presentation entitled “A biphasic gustatory strategy for lipid evaluation in Drosophila.”

In his presentation, Professor Lee discussed how Drosophila melanogaster evaluates dietary lipids, focusing on fatty acids. The work demonstrated that flies exhibit concentration-dependent behavioral responses to these compounds, with lower concentrations producing neutral or attractive responses and higher concentrations promoting aversion. The study further highlighted the involvement of distinct gustatory receptor neuron populations and ionotropic receptor pathways in lipid sensing.

Participation in the CKJ Drosophila Conference provided an important opportunity to share our laboratory’s research and strengthen scientific interactions with researchers across the international Drosophila community.
