Constitutive and conditional epitope-tagging of endogenous G protein coupled receptors in Drosophila

The paper develops a method to tag endogenous GPCRs in Drosophila for localization studies and uses it to investigate receptor distribution and function in neural circuits.

Drosophila cells that express octopamine receptors can either inhibit or promote oviposition

The paper identifies that octopamine receptors in Drosophila influence oviposition by both inhibiting and promoting egg-laying through distinct neuronal and non-neuronal mechanisms.

Mutation of the Drosophila serotonin transporter dSERT disrupts courtship and feeding and increases both daytime and nighttime sleep

This study creates dSERT mutants in Drosophila to investigate serotonin's role in sleep, feeding, and courtship, finding increased sleep and behavioral defects.

Serotonergic modulation of visual neurons in Drosophila melanogaster

This study identifies serotonin receptor expression in Drosophila visual neurons and shows serotonin modulates visual processing through calcium signaling changes.
