Lack of Single Amino Acids Transcriptionally Remodels Sensory Systems to Enhance the Intake of Protein and Microbiota

The paper identifies shared and unique transcriptional changes in Drosophila melanogaster upon individual essential amino acid deprivation, revealing mechanisms linking nutrient scarcity to behavioral and physiological responses.

A neuronal substrate for translating nutrient state and resource density estimations into foraging decisions

This study identifies a neuronal population in Drosophila that integrates nutritional state and food patch density to regulate foraging decisions.

Metabolic cross-feeding allows a gut microbial community to overcome detrimental diets and alter host behaviour

The paper shows that gut bacteria in Drosophila use metabolic cross-feeding to overcome poor diets and influence host behavior.

optoPAD: a closed-loop optogenetics system to study the circuit basis of feeding behaviors

The paper develops and validates optoPAD, a closed-loop optogenetics system to study how taste neurons influence feeding behavior in flies.

Internal amino acid state modulates yeast taste neurons to support protein homeostasis in Drosophila

The paper identifies yeast taste neurons in Drosophila that mediate yeast feeding and shows how internal amino acid states modulate these neurons to support protein homeostasis.
