Abstract

Abstract Background Traumatic brain injury (TBI) and spinal cord injury (SCI) are acquired injuries to the central nervous system (CNS) caused by external forces that cause temporary or permanent sensory and motor impairments and the potential for long‐term disability or even death. These conditions currently lack effective treatments and impose substantial physical, social, and economic burdens on millions of people and families worldwide. TBI and SCI involve intricate pathological mechanisms, and the inflammatory response contributes significantly to secondary injury in TBI and SCI. It plays a crucial role in prolonging the post‐CNS trauma period and becomes a focal point for a potential therapeutic intervention. Previous research on the inflammatory response has traditionally concentrated on glial cells, such as astrocytes and microglia. However, increasing evidence highlights the crucial involvement of lymphocytes in the inflammatory response to CNS injury, particularly CD8+ T cells and NK cells, along with their downstream XCL1‐XCR1 axis. Objective This review aims to provide an overview of the role of the XCL1‐XCR1 axis and the T‐cell response in inflammation caused by TBI and SCI and identify potential targets for therapy. Methods We conducted a comprehensive search of PubMed and Web of Science using relevant keywords related to the XCL1‐XCR1 axis, T‐cell response, TBI, and SCI. Results This study examines the upstream and downstream pathways involved in inflammation caused by TBI and SCI, including interleukin‐15 (IL‐15), interleukin‐12 (IL‐12), CD8+ T cells, CD4+ T cells, NK cells, XCL1, XCR1+ dendritic cells, interferon‐gamma (IFN‐γ), helper T0 cells (Th0 cells), helper T1 cells (Th1 cells), and helper T17 cells (Th17 cells). We describe their proinflammatory effect in TBI and SCI. Conclusions The findings suggest that the XCL1‐XCR1 axis and the T‐cell response have great potential for preclinical investigations and treatments for TBI and SCI.

  • Cellular mechanisms like apoptosis and autophagy may contribute to progressive hypothalamic-pituitary damage after TBI.

    “Furthermore, cellular mechanisms like apoptosis and autophagy may contribute to progressive hypothalamic–pituitary damage [7,53,54].”

    From Endocrine Dysfunctions After Pediatric Traumatic Brain Injury: Present Insights and Future Directions (2025) · cites this paper as [54]

    The Pathophysiology of TBI section identifies apoptotic cell death as a mechanism of secondary injury, which can persist after TBI. It does not state that autophagy contributes to progressive hypothalamic–pituitary damage; a paper on apoptosis and autophagy in the HPA axis appears only in the References. (LLM, conf=0.86)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
