{Reference Type}: Journal Article {Title}: STX-bpc: "Brightening" the path to neuronal inhibition. {Author}: Wan J;Li Y; {Journal}: Cell Chem Biol {Volume}: 31 {Issue}: 7 {Year}: 2024 Jul 18 {Factor}: 9.039 {DOI}: 10.1016/j.chembiol.2024.06.008 {Abstract}: In this issue of Cell Chemical Biology, Elleman et al.1 introduce a transformative chemical approach to control neuronal activity with high spatial and temporal resolution. The authors present STX-bpc, a potent neurotoxin that naturally inhibits voltage-gated sodium channels (NaVs), complementing available optogenetic methods for manipulating neuronal activity, cellular communication, and behavior.
