[Neuro-immune interactions in the tumor microenvironment: from mechanisms to precision therapy]

The nervous system, as the core hub of physiological regulation in the human body, plays a key role in the tumor microenvironment through the neuro-immune-tumor axis. Studies have shown that tumor-infiltrating nerve fibers regulate immune cell functions by releasing neurotransmitters, while immune cells can feedback and modulate neuronal activity, forming a dynamic bidirectional interaction network. The emerging field of cancer neuroimmunology focuses on the complex dialogue mechanisms between the nervous and immune systems in the tumor microenvironment. In-depth analysis of the neuro-immune interaction network not only provides new perspectives for understanding tumor immune escape, but also lays the theoretical foundation for developing novel combination therapies targeting the neuro-immune axis, potentially providing breakthrough strategies to overcome resistance to current immunotherapies.
