Abstract

Chronic inflammation, a decline in immune responsiveness, and reduced cardiovascular function are all associated with aging, but the relationships among these phenomena remain unclear. Here, we longitudinally profiled a total of 84 signaling conditions in 91 young and older adults and observed an age-related reduction in cytokine responsiveness within four immune cell lineages, most prominently T cells. The phenotype can be partially explained by elevated baseline levels of phosphorylated STAT (pSTAT) proteins and a different response capacity of naive versus memory T cell subsets to interleukin 6 (IL-6), interferon α (IFN-α), and, to a lesser extent, IL-21 and IFN-γ. Baseline pSTAT levels tracked with circulating levels of C-reactive protein (CRP), and we derived a cytokine response score that negatively correlates with measures of cardiovascular disease, specifically diastolic dysfunction and atherosclerotic burden, outperforming CRP. Thus, we identified an immunological link between inflammation, decreased cell responsiveness in the JAK-STAT pathway, and cardiovascular aging. Targeting chronic inflammation may ameliorate this deficiency in cellular responsiveness and improve cardiovascular function.

  • The primary outcome, cytokine response score difference from baseline to end of intervention, was not significant in either arm.

    “The primary outcome of cytokine response score (Shen-Orr et al., 2016) difference from baseline to end of intervention was not significant for either arm of the study (Table S4), nor were race or gender significant covariates.”

  • Systemic chronic inflammation can impair normal immune function, increasing susceptibility to infections and tumors and reducing vaccine response.

    “SCI can also impair normal immune function, leading to increased susceptibility to infections and tumors and a poor response to vaccines22–25.”
  • Elevated SCI can produce low-grade continuous activation of pathways like JAK-STAT in leukocytes, which weakens the acute response of immune cells from older adults with chronic inflammation to various stimuli, because phosphorylation of these proteins increases less after stimulation.

    “elevated SCI can lead to a basal low-grade constitutive activation of various signaling pathways, such as the Janus kinase/signal transducers and activators of transcription (JAK–STAT) system in leukocytes, which results in a weakened acute response to multiple stimuli in immune cells from older adults with chronic inflammation due to reduced fold-increase in the levels of phosphorylation of these”
  • Increased proinflammatory cytokines or danger signals cause constitutive low-level engagement of JAK-STAT, MyD88, NF-κB and inflammasome signalling, producing high basal activation but impaired responses to further stimulation.

    “The increased presence of proinflammatory cytokines or danger signals leads to constitutive low-level engagement of immune cell signaling events such as JAK-STAT, MyD88, NF-κB, and inflammasomes, resulting in high basal activation but impaired immune cell responses to further cytokine and pattern recognition receptor (PRR) stimulation17,18.”

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.
