Abstract

Summary: Aging is the greatest risk factor for the development of chronic diseases such as arthritis, type 2 diabetes, cardiovascular disease, kidney disease, Alzheimer's disease, macular degeneration, frailty, and certain forms of cancers. It is widely regarded that chronic inflammation may be a common link in all these age‐related diseases. This raises the question, can one alter the course of aging and potentially slow the development of all chronic diseases by manipulating the mechanisms that cause age‐related inflammation? Emerging evidence suggests that pro‐inflammatory cytokines interleukin‐1 (IL‐1) and IL‐18 show an age‐dependent regulation implicating inflammasome‐mediated caspase‐1 activation in the aging process. The Nod‐like receptor (NLR) family of innate immune cell sensors, such as the nucleotide‐binding domain, leucine‐rich‐containing family, pyrin domain‐containing‐3 (NLRP 3) inflammasome controls the caspase‐1 activation in myeloid‐lineage cells in several organs during aging. The NLRP 3 inflammasome is especially relevant to aging as it can get activated in response to structurally diverse damage‐associated molecular patterns (DAMP s) such as extracellular ATP, excess glucose, ceramides, amyloids, urate, and cholesterol crystals, all of which increase with age. Interestingly, reduction in NLRP 3‐mediated inflammation prevents age‐related insulin resistance, bone loss, cognitive decline, and frailty. NLRP 3 is a major driver of age‐related inflammation and therefore dietary or pharmacological approaches to lower aberrant inflammasome activation holds promise in reducing multiple chronic diseases of age and may enhance healthspan.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Monocytes and tissue-resident macrophages are predominant producers of SASP factors such as IL-1α, IL-1β, IL-6, TNF, and HMGB1.

    “Studies have shown that immune cells, including monocytes and tissue-resident macrophages, are the predominant producers of SASP factors such as IL-1α, IL-1β, IL-6, TNF and HMGB1 (refs. 75–78).”

    From SenNet recommendations for detecting senescent cells in different tissues (2024) · cites this paper as [75]

    The “Metabolic disease/T2D” section (page not supplied) credits inflammatory M1 macrophages with increased TNFα, IL-6, and IL-1β in obesity. The “Age-related diseases and inflammation” section says macrophages are major responders to danger signals in aged tissues, but does not establish that monocytes and tissue-resident macrophages are the predominant producers of SASP factors generally, or identify them as producers of IL-1α and HMGB1.

  • Chronic systemic inflammation is associated with aging, is low-grade and persistent, and ultimately causes collateral damage to tissues and organs.

    “This type of inflammation is associated with aging and is characterized by being low-grade and persistent, ultimately leading to collateral damage to tissues and organs1,17.”
  • Chronic serum hyperuricemia positively correlates with inflammation, DNA damage and OS, and has been implicated in pathogenesis of several disorders, including renal, metabolic, and cardiovascular diseases.

    “Accordingly, chronic serum hyperuricemia positively correlates with inflammation, DNA damage and OS, and has been implicated in the pathogenesis of several disorders, including renal, metabolic, and cardiovascular diseases [214,217,218].”

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.
