Neurotransmitters: promising immune modulators in the tumor microenvironment

Area of Science:

• Oncology
• Neuroimmunology
• Cancer Biology

Background:

• The tumor microenvironment (TME) significantly influences cancer progression and therapy response.
• Cellular and acellular components dynamically modulate the TME throughout tumor development.
• Neural and immune factors are increasingly recognized for their synergistic roles in TME modulation.

Purpose of the Study:

• To explore the intricate interplay between the nervous and immune systems within the TME.
• To elucidate the specific mechanisms by which neurotransmitters regulate cancer progression.
• To identify novel therapeutic targets within the neuro-immune axis of the TME.

Main Methods:

• Review of existing literature on neuro-immune interactions in cancer.
• Analysis of studies investigating neurotransmitter functions in the TME.
• Comparative analysis of TME modulation by neural versus immune components.

Main Results:

• Neurotransmitters play crucial, yet not fully understood, regulatory roles in TME modulation.
• The synergistic action of neural and immune factors significantly impacts tumor initiation, growth, invasion, metastasis, and therapy response.
• Current TME-targeting therapies show limitations, highlighting the need for novel approaches.

Conclusions:

• Revealing the molecular mechanisms of nervous and immune system interplay in cancer is critical.
• A deeper understanding of these interactions can provide a clearer picture of tumor development.
• Targeting the neuro-immune axis in the TME holds significant promise for improving clinical cancer treatment.
