Abstract

Immune checkpoint inhibitors (ICIs) have transformed the treatment of various cancers, including malignancies once considered untreatable. These agents, however, are associated with inflammation and tissue damage in multiple organs. Myocarditis has emerged as a serious ICI-associated toxicity, because, while seemingly infrequent, it is often fulminant and lethal. The underlying basis of ICI-associated myocarditis is not completely understood. While the importance of T cells is clear, the inciting antigens, why they are recognized, and the mechanisms leading to cardiac cell injury remain poorly characterized. These issues underscore the need for basic and clinical studies to define pathogenesis, identify predictive biomarkers, improve diagnostic strategies, and develop effective treatments. An improved understanding of ICI-associated myocarditis will provide insights into the equilibrium between the immune and cardiovascular systems.

  • The discovery of α-MyHC-specific T cells in ICI myocarditis suggests potential involvement of autoreactive T cells targeting α-MyHC in the initiation and progression of other forms of myocarditis.

    “This discovery suggests a potential involvement of autoreactive T cells targeting α -MyHC in the initiation and progression of other forms of myocarditis.”

    From Autoimmune Myocarditis, Old Dogs and New Tricks. (2024) · cites this paper as [44]

    The “Mechanisms of ICI-associated myocarditis” section describes α-myosin-heavy-chain–reactive T cells in a model of autoimmune myocarditis, supporting their potential relevance to other forms of myocarditis. But it identifies the antigens that elicit T-cell responses in ICI-associated myocarditis as an open question; it does not report the claimed discovery of α-MyHC-specific T cells in ICI myocarditis. Page numbers are unavailable in our copy. (LLM, conf=0.84)

    Experimental — accuracy not yet measured
  • Recent cases of ICI myocarditis have expanded insights into the role of α-MyHC-specific T cells in myocarditis development.

    “Recent cases of ICI myocarditis have expanded our insights into the role of α -MyHC-specific T cells in myocarditis development. 41-46”

    From Autoimmune Myocarditis, Old Dogs and New Tricks. (2024) · cites this paper as [44]

    The Mechanisms of ICI-associated myocarditis section describes α-myosin-heavy-chain-reactive T cells in a mouse model of autoimmune myocarditis. It explicitly says that mechanism had not yet been explored in ICI-associated myocarditis and identifies the antigens driving ICI-associated T-cell responses as an open question. The paper therefore supports a role for these T cells in myocarditis generally, but not the claimed insight from recent ICI myocarditis cases. (LLM, conf=0.85)

    Experimental — accuracy not yet measured
  • ICI myocarditis is an infrequent but potentially fatal condition associated with ICI therapies, especially when used in combination.

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.
