A Key Player in Cellular Communication: Neuronal Calcium Signaling

Neuronal calcium signaling is an important process that manages numerous vital functions in neural networks. Understanding neuronal calcium signaling is not only fundamental to neuroscience, it is also key to unlocking potential therapies and improving our understanding of neurological disorders.

At Creative Biolabs, we provide an overview of neuronal calcium signaling research, explore the regulatory mechanisms at play, and offer related services and products to facilitate your research project.

Neuronal Calcium Signaling: An Overview

Neuronal calcium signaling is a complex and finely regulated system that is essential for neurotransmission, nerve growth, synaptic plasticity and cell survival. There are two key elements to this process: Ca2+ and complex calcium channels within the neuron that facilitate calcium ion transport.

The process begins with the entry of Ca2+ into the neuron via voltage-gated calcium channels (VGCCs) that are activated in response to changes in membrane potential. In addition, synaptically released neurotransmitters can trigger the opening of these channels, allowing a massive influx of calcium into the cell. Once inside, Ca2+ binds to specific proteins (e.g. calmodulin), triggering a series of events that ultimately lead to the desired cellular response.

Major Contributors to Neuronal Calcium Signaling

  • VGCCs
    VGCCs are a group of voltage-gated ion channels found in neurons' cell membranes. These channels are controlled by the cell's membrane potential and allow the regulated influx of calcium ions from the extracellular to intracellular space. The calcium influx via VGCCs is key to many neuronal activities including neurotransmitter release and neuron firing.
    There are several types of VGCCs, each with a unique role in modulating neuronal activities. N, P/Q, and R type channels are predominantly located in neurons and play critical roles in neurotransmitter release.
  • Neurotransmitters
    Neurotransmitters are chemical messengers that transmit signals across the synapse and help regulate calcium signaling. When an action potential reaches the presynaptic terminal, the neurotransmitter is released into the synaptic gap and binds to receptors on the postsynaptic membrane. This interaction usually results in the opening of voltage-gated calcium channels, which initiate calcium signaling within the postsynaptic neuron. Creative Biolabs provides a full range of in vitro neurotransmitter detection assays that enable researchers to comprehensively study different neurotransmitters.

  • N-methyl-D-aspartate Receptors (NMDARs)
    NMDARs are a subtype of glutamate receptors that play a critical role in mediating calcium influx into neuronal cells after synaptic activation. Activation of NMDARs allows the entry of Ca2+ into the cell, acting as crucial links between membrane depolarization, intracellular Ca2+ elevation, and subsequent activation of intracellular signaling mechanisms. Importantly, these receptors have a critical role in synaptic plasticity, a cellular mechanism for learning and memory.
  • Metabotropic Glutamate Receptors (mGluRs)
    mGluR couples to intracellular signaling pathways via G proteins. These receptors regulate calcium signaling by affecting intracellular calcium release or by modulating the activity of ion channels. Group I mGluRs (mGluR1 and mGluR5) are commonly associated with the activation of phospholipase C, resulting in the production of inositol triphosphate (IP3) and diacylglycerol (DAG). IP3 in turn triggers the release of calcium from the endoplasmic reticulum. mGluRs are also known to inhibit adenylate cyclase and regulate potassium channels. On the other hand, group II and III mGluRs regulate calcium levels by inhibiting adenylate cyclase and regulating potassium channels.
  • Ryanodine Receptors and Intracellular Calcium Release
    Ryanodine receptors are intracellular calcium-release channels primarily located on the membrane of the endoplasmic reticulum. Activation of these receptors, often secondary to an initial influx of calcium ions through VGCCs or NMDARs, leads to a surge of calcium release from internal stores into the cytoplasm, further amplifying the intracellular calcium signal. This process, known as calcium-induced calcium release (CICR), can be critical for the regulation of numerous neuronal functions.
  • Inositol 1, 4, 5-trisphosphate Receptors (IP3Rs)
    Located on the endoplasmic reticulum (ER), IP3Rs are activated by IP3, produced following the stimulation of phospholipase C-coupled membrane receptors. Three IP3R isoforms exist, each with unique sensitivity and expression levels, strongly impacting calcium release. Intriguingly, IP3Rs can act collectively as both the trigger and amplifier for calcium signals by conversing with other calcium release channels like RyRs.
  • Calcium Binding Proteins

    Calcium binding proteins (Creative Biolabs Authorized)

    Calcium-binding proteins, such as calmodulin and parvalbumin, contribute significantly to calcium homeostasis and signaling. These proteins bind calcium ions and act as buffers, modulating the duration and spatial extent of intracellular calcium signals. Additionally, by binding to calcium ions, they can regulate the activity of other calcium-dependent proteins and enzymes, further influencing diverse cellular activities.

  • Calcium ATPases
    The two main types - Plasma membrane calcium ATPase (PMCA) and Sarco/Endoplasmic reticulum calcium ATPase (SERCA), function to remove calcium from the cytosol, therefore, controlling calcium signals' duration and amplitude. PMCA pumps Ca2+ out into the extracellular space, while SERCA transports Ca2+ back into the intracellular reservoirs in the sarcoplasmic or endoplasmic reticulum.
