When neurons are stimulated, calcium entry into mitochondria upregulates mitochondrial energy production, but glycolytic energy production in the cytosol is stimulated by elevated energy demand, not Ca2+ signaling.
Optogenetic and electrical low-frequency stimulation in the sclerotic hippocampus prevents the emergence of spontaneous focal and evoked generalized seizures in a mouse epilepsy model.

Biochemical and biological studies reveal that caspases feed back onto the Unfolded Protein Response by cleaving the ER-stress sensor IRE1 to produce a cytoprotective N-terminal fragment that inhibits BAX-dependent apoptosis.
Minian is an open-source analysis pipeline for calcium imaging data that enhances usability with low memory demands and transparency with user-friendly interactive visualizations.

DExCon, LUXon, and DExogron approaches simultaneously block endogenous gene expression and permit tuning of re-expression levels in time and space; proof-of-principle reveals unforeseen differences in protein kinetics, cargo handling, and cell migration regulation between closely related Rab11 family members.
