The neuro-immune axis in cancer: mechanisms of neural regulation of immunity within the tumor microenvironment to promote cancer progression.
Review in Frontiers in immunology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The tumor microenvironment (TME) is a complex and dynamic ecosystem composed of cancer cells, stromal cells, immune cells, and the extracellular matrix, which significantly influences the initiation, progression, and therapeutic response of cancer. Emerging evidence indicates a crucial interaction between the nervous and immune systems within the TME, forming a "neuro-immune axis" that profoundly impacts tumor biology. This review not only synthesizes current knowledge on this critical bidirectional crosstalk but also offers a fresh perspective by critically evaluating underappreciated aspects such as the neural differentiation of cancer stem cells and the challenges in translating preclinical findings into clinical therapies. On one hand, tumor cells actively promote nerve recruitment and remodeling through tumor innervation, neurogenesis, and perineural invasion. In turn, neural signals-including adrenergic, cholinergic, and sensory neuropeptides-orchestrate immunosuppression by modulating key immune cell populations such as T cells, macrophages, and myeloid-derived suppressor cells (MDSCs). Consequently, neural signaling promotes immune escape, tumor progression and therapeutic resistance. This review further critically evaluates the translational potential of targeting these neuro-immune interactions, highlighting combination strategies designed to enhance the efficacy of cancer immunotherapy.
