Drosophila glutathione S-transferase S1 exacerbates phenotypes of the gain-of-function voltage-gated sodium channel mutant paraShu through a hemocyte-mediated mechanism

James A. Mrkvicka, Wayne A. Johnson, Junko Kasuya, Toshihiro Kitamoto

This study shows that GstS1 in Drosophila exacerbates hyperexcitability in paraShu mutants through hemocyte-mediated neuroimmune interactions.
