Summary
Calcium store depletion induces intrinsic neuronal plasticity, a region-specific adaptation that may shield neurons from harmful calcium signaling changes. This finding reveals a novel mechanism for neuronal resilience.
Area of Science:
- Neuroscience
- Cellular Biology
- Calcium Signaling
Background:
- Neuronal excitability is influenced by intracellular calcium levels.
- The effects of calcium store depletion on intrinsic neuronal properties remain largely unexplored.
Discussion:
- Narayanan et al. report a novel form of intrinsic plasticity triggered by calcium store depletion.
- This plasticity is characterized by its regional restriction within neurons.
- The study suggests this mechanism may serve a protective role against aberrant calcium signaling.
Key Insights:
- Calcium store depletion induces a specific, localized change in neuronal intrinsic properties.
- This depletion-induced plasticity offers a potential neuroprotective mechanism.
- Understanding this process is crucial for deciphering neuronal responses to calcium dysregulation.
Outlook:
- Further research can elucidate the precise molecular pathways underlying this plasticity.
- Investigating this phenomenon in disease models may reveal therapeutic targets.
- This discovery opens new avenues for understanding neuronal adaptation and resilience.

01:27Feedback Regulation of Calcium Concentration
Calcium is an essential signaling molecule required for various cellular functions. Calcium pumps and ion channels on cell and organellar membranes, such as those on the endoplasmic reticulum (ER), regulate calcium concentrations inside the cell. They remain closed, keeping the cytosolic calcium levels low at a resting state.
Various transmembrane receptors, such as G protein-coupled receptors (GPCRs), elicit a response to extracellular signals by increasing cytosolic calcium. Activated GPCRs...

01:16Calmodulin-dependent Signaling
Calmodulin (CaM) is a calcium-binding protein in eukaryotes that controls various calcium-regulated cellular processes. It has four calcium-binding sites that bind calcium to form the calcium-calmodulin ( Ca2+-CaM) complex. GPCR stimulation increases the calcium levels in the cells that bind to CaM and induces a conformational change.
The Ca2+-CaM complex does not have enzymatic activity by itself. Instead, the complex binds downstream target proteins, including membrane proteins or enzymes,...
