Presynaptic Gαo (GOA-1) signals to depress command neuron excitability and allow stretch-dependent modulation of egg laying in Caenorhabditis elegans

Bhavya Ravi, Jian Zhao, Sana I. Chaudhry, Rossana Signorelli, Mattingly K. Bartole, Richard J. Kopchock, Christian Guijarro, Joshua M. Kaplan, Lijun Kang, Kevin M. Collins

The paper shows that Go signaling in HSN neurons inhibits egg-laying activity and allows stretch-dependent modulation of egg laying in C. elegans.

Serotonin signals through postsynaptic Gαq, Trio RhoGEF, and diacylglycerol to promote C. elegans egg-laying circuit activity and behavior

Pravat Dhakal, Sana I. Chaudhry, Rossana Signorelli, Kevin M. Collins

The paper investigates how serotonin signaling through Gq, PLCβ, and Trio RhoGEF promotes egg-laying behavior in C. elegans by modulating DAG levels and distinct effector pathways.
