CXCR4 signaling in health and disease

Area of Science:

• Immunology
• Molecular Biology
• Cell Biology

Background:

• Chemokines and their receptors orchestrate critical cellular processes, including morphogenesis, angiogenesis, and immune responses.
• The chemokine receptor CXCR4 exhibits pleiotropic functions and is implicated in various pathologies such as immune disorders, viral infections, and cancer.
• CXCR4's multifaceted roles establish it as a significant target for therapeutic interventions.

Purpose of the Study:

• To review the properties and signaling pathways of the CXCR4 receptor in both physiological and pathological contexts.
• To highlight the specific involvement of CXCR4 in WHIM syndrome, an inherited immunodeficiency.
• To underscore CXCR4's importance as a drug development target.

Main Methods:

• Literature review of scientific publications on CXCR4.
• Analysis of CXCR4's role in cellular processes and disease pathogenesis.
• Focus on genetic mutations leading to WHIM syndrome.

Main Results:

• CXCR4 is essential for normal biological functions and its dysregulation contributes to disease.
• Mutations in the CXCR4 gene are the underlying cause of WHIM syndrome, characterized by immunodeficiency.
• Understanding CXCR4 signaling provides insights into therapeutic strategies for various conditions.

Conclusions:

• CXCR4 is a pivotal molecule in immunity and disease, necessitating further research for therapeutic applications.
• Targeting CXCR4 offers potential for treating conditions ranging from viral infections to cancers and immunodeficiencies like WHIM syndrome.
• This review consolidates current knowledge on CXCR4, emphasizing its therapeutic relevance.
