cGMP signaling regulates context-dependent sensory valence in C. elegans

Ricardo F. Frausto, Navonil Banerjee, Michelle L. Castelletto, Ava E Bignell, Breanna Walsh, Elissa A. Hallem

This study shows that cGMP signaling via EGL-4 in C. elegans BAG neurons determines context-dependent CO2 sensory valence based on satiety state and cultivation conditions.

Neuronally sensed oxygen drives behavior and development in human-infective, skin-penetrating nematodes

Breanna Walsh, Navonil Banerjee, Gloria Bartolo, Elissa A. Hallem

This study shows that skin-penetrating parasitic nematodes detect and respond to oxygen levels, with neuronal sensing influencing behavior and development.

Carbon dioxide shapes parasite-host interactions in a human-infective nematode

Navonil Banerjee, Spencer S. Gang, Michelle L. Castelletto, Breanna Walsh, Felicitas Ruiz, Elissa A. Hallem

This study shows that CO2 influences different life stages of the nematode Strongyloides stercoralis, affecting their behavior and development during host interaction.
