Abstract

Significance: Aging is a risk factor for heart diseases, and it is also known to impact on several immunological processes. Nevertheless, most studies addressing the cardio-immune cross-talk have focused on juvenile rather than senescent animal models. In the present study, we addressed this gap and found that immunological activity contributes to myocardial aging. By using different lymphocyte-deficient animal models and heterochronic adoptive cell-transfer protocols, our study revealed a pivotal role for CD4 + T cells in mediating spontaneous local inflammation and mild organ dysfunction in aged hearts. These results might shed new light on the emerging field of “immunocardiology” because they reveal that spontaneous heart-directed immune responses arise even in the absence of previous myocardial tissue damage.

  • Accumulation of activated memory cardiac T cells in the mediastinal lymph node and myocardium is associated with myocardial aging, leading to significantly lower cardiac output.

    “Another investigation demonstrated that the accumulation of activated memory cardiac T cells in the mediastinal lymph node and myocardium is associated with myocardial aging, leading to significantly lower cardiac output. 271,300,301”

    From Autoimmune Myocarditis, Old Dogs and New Tricks. (2024) · cites this paper as [271]

    The sections on spontaneous CD4+ T-cell activation and immune–somatic factors report activated effector-memory T cells in the mediastinal lymph nodes of aged mice and increased myocardial infiltration by T cells from aged donors. The myocardial-aging results report significantly reduced fractional shortening, not significantly lower cardiac output. The paper also says those T cells alone did not cause major cardiac alterations, so the claim overstates their causal effect. (LLM, conf=0.88)

  • Aged mice harbor a significantly higher number of α-MyHC-specific T cells within the heart and an increased number of IFNγ-producing T cells in heart-draining lymph nodes compared with young adult mice.

    “Animal studies have shown that aged mice harbor a significantly higher number of α -MyHC-specific T cells within the heart and an increased number of IFNγ -producing T cells in heart-draining lymph nodes compared with young adult mice. 42,271”

    From Autoimmune Myocarditis, Old Dogs and New Tricks. (2024) · cites this paper as [271]

    The section on spontaneous T-cell activation in mediastinal lymph nodes (page unavailable) reports an age-related increase in activated CD4+ T cells in heart-draining nodes; the paper also reports accumulation of IFN-γ-producing effector CD4+ T cells there. It does not establish that aged mice have significantly more α-MyHC-specific T cells within their hearts than young mice. Its myosin-specific finding concerns antibodies, not T cells.

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.
