The membrane-tethered cis-ligand Belly roll elicits GPCR signaling thereby enabling adaptive avoidance behaviors

Yuma Tsukasa, Takumi Ohbayashi, Misato Kurio…·Tadao Usui

The paper identifies a neural circuit and molecular mechanism in Drosophila larvae that links internal osmotic state to behavioral adaptation through GPCR signaling.

A GPI-anchored Ly6/uPAR superfamily gene belly roll is expressed in multiple peptidergic neurons in Drosophila melanogaster larvae

Yuma Tsukasa, Tadashi Uemura, Tadao Usui

This study identifies the expression pattern of the GPI-anchored LU superfamily gene bero in Drosophila larvae, showing it is expressed in peptidergic neurons and non-neuronal tissues.

Refinement of a technique for collecting and evaluating the osmolality of haemolymph from Drosophila larvae

Misato Kurio, Yuma Tsukasa, Tadashi Uemura, Tadao Usui

This study refines methods for collecting and measuring haemolymph osmolality in Drosophila larvae, concluding the true value is approximately 306.0 mOsm kg-1.
