CRAC channels as targets for immunotherapy.

Area of Science:

• Immunology
• Cell Biology
• Pharmacology

Background:

• Calcium release-activated calcium (CRAC) channels regulate store-operated calcium entry in immune and non-immune cells.
• CRAC channels are critical for immune cell function and implicated in immune-related disorders.
• Mutations in ORAI1 and STIM1 genes, encoding CRAC channel components, cause inborn errors of immunity.

Purpose of the Study:

• To provide an overview of CRAC channels in immune cell function.
• To review the role of CRAC channels in preclinical models of immune diseases.
• To discuss the outcomes of clinical trials involving CRAC channel inhibitors (CRACi).

Main Methods:

• Review of existing literature on CRAC channel function in immunity.
• Analysis of preclinical studies using knockout mice and CRAC inhibitors.
• Examination of clinical trial data for CRAC inhibitors in inflammatory disorders.

Main Results:

• CRAC channels are essential for the function of various immune cell types.
• Preclinical studies confirm CRAC channel involvement in infection immunity, autoimmunity, allergy, and inflammation.
• Clinical trials suggest CRAC inhibitors have potential as immunotherapies for inflammatory diseases.

Conclusions:

• CRAC channels play a fundamental role in immune responses and disease pathogenesis.
• CRAC inhibitors represent a promising therapeutic strategy for immune-related and inflammatory conditions.
• Further clinical investigation of CRAC inhibitors is warranted for immunotherapy.
