Insulin signaling accelerates the anterograde movement of Rab4 vesicles in axons through Klp98A/KIF16B recruitment via Vps34-PI3Kinase

Kamaldeep Singh, Semanti Das, Sabyasachi Sutradhar…·Krishanu Ray

This study shows insulin signaling increases Rab4 vesicle transport in axons by recruiting Klp98A via Vps34-PI3Kinase activation in Drosophila.

Focal Laser Stimulation of Fly Nociceptors Activates Distinct Axonal and Dendritic Ca2+ Signals

Rajshekhar Basak, Sabyasachi Sutradhar, Jonathon Howard

This study uses laser stimulation to show that Drosophila Class IV nociceptors have two distinct pathways for mechanical stimulus detection: direct dendritic contact and non-contact via diffusible molecules.
