SOCE in neurons: Signaling or just refilling?

Area of Science:

• Neuroscience
• Cell Biology
• Biochemistry

Background:

• Store-operated calcium entry (SOCE) is a fundamental calcium influx mechanism.
• Its role in neuronal calcium homeostasis and signaling is under active investigation.
• Key proteins involved include STIM, Orai, and TRP channels.

Purpose of the Study:

• To review current knowledge on SOCE in neurons.
• To investigate the signaling functions of calcium entering neurons via SOCE.
• To explore the therapeutic potential of targeting SOCE in brain diseases.

Main Methods:

• Literature review of existing research on SOCE in neurons.
• Analysis of data on the roles of STIM, Orai, and TRP channels in neuronal calcium dynamics.
• Examination of evidence linking SOCE dysregulation to neurodegenerative diseases.

Main Results:

• SOCE is essential for refilling ER calcium stores and also has direct signaling roles in neurons.
• Components of the SOCE machinery (STIM, Orai, TRP channels) are integral to important neuronal processes.
• Dysregulation of calcium homeostasis and SOCE is implicated in neurodegenerative conditions.

Conclusions:

• SOCE plays multifaceted roles in neuronal physiology beyond simple calcium store refilling.
• Targeting SOCE components presents a promising avenue for developing novel therapeutics for neurological and brain disorders.
• Further research into SOCE mechanisms could uncover new strategies for treating neurodegenerative diseases.
