[B cells in head and neck oncology]

Area of Science:

• Oncology
• Immunology
• Cancer Research

Background:

• Immunotherapy is vital for head and neck cancer (HNC) treatment.
• Tumor-infiltrating B cells (TIL-B) are increasingly recognized for their role in HNC.
• Regulatory B cells (Breg) are immunosuppressive TIL-B subsets.

Purpose of the Study:

• To review recent findings on B cells and adenosine in HNC.
• To highlight the therapeutic potential of targeting B cells in HNC immunotherapy.
• To understand the immunological landscape of HNC for combined treatment strategies.

Main Methods:

• Literature review of B cell functions in HNC.
• Analysis of adenosine production by regulatory B cells.
• Exploration of B cell-mediated immunosuppression in the tumor microenvironment.

Main Results:

• B cells, especially Breg, significantly influence HNC growth.
• Breg secrete immunosuppressive IL-10 and adenosine.
• Adenosine is a key immunosuppressive mediator in the HNC tumor microenvironment.

Conclusions:

• Understanding B cell roles and adenosine is crucial for HNC immunotherapy.
• Targeting Breg and adenosine pathways may enhance treatment efficacy.
• Integrating immunotherapy with standard HNC treatments can improve outcomes.
