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.

In recent years, immunotherapy has gained increasing attention as a novel paradigm in cancer treatment. Unlike conventional therapies that directly target tumor cells, immunotherapy seeks to harness the host immune system to eradicate malignancies. However, the profoundly immunosuppressive tumor microenvironment characteristic of GBM severely limits the effectiveness of immunotherapeutic approaches. In addition, the blood-brain barrier (BBB) poses a formidable obstacle to the delivery of therapeutic agents to intracranial tumors. Consequently, effective immunotherapy for GBM requires strategies that both enable efficient BBB penetration and overcome local immunosuppression within the tumor microenvironment. This review first summarizes the immune system of the central nervous system (CNS), the immunosuppressive mechanisms underlying GBM progression, and current immunotherapeutic strategies for GBM. We then discuss recent advances in nanomaterial-based immunotherapy for GBM, focusing on four major approaches: immune checkpoint inhibition, targeting tumor-associated immune cells, stimulation of immune responses via immunogenic cell death, and combination therapies.
