Neuroimmune braking mechanisms in exercise-related musculoskeletal injury: from nociceptors to tissue regeneration.
Review in Journal of neuroinflammation, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundMusculoskeletal injuries are a frequent occurrence in sports medicine and rehabilitation, and their healing process needs an accurate response from inflammation. Recent studies show that sensory neurons play a critical role in tissue repair through neuropeptides, which is quite different from their usual function as simple pain detectors. The current review summarizes studies conducted during the last ten years concerning neuroimmune crosstalk mechanisms in musculoskeletal injury healing, in which the role of sensory neurons in macrophage polarization is emphasized.
methodsWe reviewed preclinical studies on the neuro-immune interaction after musculoskeletal injury, emphasizing the CGRP-RAMP1-thrombospondin-1 axis and parallel pathways including TGF-β-mediated macrophage specification and TAFA4-IL-10 signaling. Based on rodent data regarding skin wounds, muscle injury, peripheral nerve injury, and other pertinent models, a theoretical model relating mechanical loading and neuroimmune inhibition was established.
resultsCGRP-RAMP1-Thrombospondin 1 signaling pathway has been identified in preclinical studies as an candidate pathway for shifting macrophages from a pro-inflammatory (M1) to a pro-repair (M2) phenotype, hence balancing the process of pathogen clearance against tissue repair process. Parallel systems, such as TGF-β-mediated macrophage specification and TAFA4-IL-10 signaling, provide redundancy and robustness. Controlled loading, as seen with active recovery, causes stimulation of sensory neuron terminals, leads to the release of neuropeptides, triggers the neuroimmune braking process, and promotes proper M1-to-M2 conversion. The understanding of these mechanisms explains why patients have always been advised to undertake active recovery rather than rest following tendon/ligament damage.
conclusionThis review proposes a new conceptual framework in which the neuroimmune axis may serve as a key controller of musculoskeletal repair. These biological mechanisms offer a potential explanation for the medical choice of active recovery over complete rest following specific injuries; nevertheless, there is no direct evidence in humans, and this theory needs to be tested in human studies.
