Disrupting neuro-immune feedback loops: novel targets to amplify cancer immunotherapy
Year: 2026
Type: article
Abstract: Nervous system and immune system have tight interactions that modulate both nerves and immune cells' activities. The interplay between the nervous and immune systems within the tumor microenvironment is a critical yet underexplored determinant of cancer immunotherapy efficacy. This review presents a new model called the Neuro-Immune Feedback Loop, which suggests that two-way communication (like the immunosuppressive effects of norepinephrine and the influence of cytokines on nerve activity) creates self-perpetuating cycles that tumors use to avoid immune responses. We compile evidence regarding neurotransmitters (such as dopamine), neuropeptides (like CGRP) to suggest innovative strategies to disrupt the immune-nerve loops. The current review proposes that context-sensitive neuro-immune switches (for instance, the dual functions of GABA) and multi-target therapies (such as CRISPR-modified neurons combined with immune checkpoint inhibitors (ICIs) could enhance immunotherapy effectiveness. By connecting neuroscience with immunology and oncology, this review aims to provide a roadmap for overcoming resistance to immunotherapies, presenting testable ideas and a new approach for precision cancer treatment. Literature search: PubMed, Scopus, and Web of Science were searched for relevant studies published between January 2000 and March 2026, with emphasis on recent publications (2024-2026) related to neuro-immune interactions in cancer.
