The Role of Rarely Studied Chemokines in Tumor Progression in Multiple Myeloma (MM)

Area of Science:

• Hematology
• Oncology
• Immunology

Background:

• Multiple myeloma (MM) is a plasma cell neoplasm.
• Research on chemokines in MM pathogenesis has mainly focused on specific ligands like CCL3, CXCL12, and their receptors.
• The roles of numerous other chemokines in MM remain underexplored.

Purpose of the Study:

• To review the significance of lesser-known chemokines in multiple myeloma.
• To elucidate their impact on tumor processes, including bone destruction, angiogenesis, and chemoresistance.
• To assess their influence on immune cell recruitment and mesenchymal stromal cells within the MM niche.

Main Methods:

• Literature review compiling current knowledge on lesser-known chemokines in MM.
• Description of the effects of specific chemokines (e.g., CXCL13, CCL2, CCL4, CCL5) on MM pathogenesis.
• Bioinformatic analysis to highlight the significance of these chemokines in MM.

Main Results:

• Lesser-known chemokines significantly influence MM tumor processes.
• These chemokines affect bone destruction, angiogenesis, and chemoresistance.
• They play crucial roles in recruiting various cells, including macrophages and lymphocytes, into the MM niche.

Conclusions:

• The review highlights the importance of understudied chemokines in multiple myeloma.
• These chemokines impact key MM pathologies and cellular interactions.
• Targeting these chemokines presents a potential therapeutic strategy for MM treatment.
