What it is Filled

A stable state in which cells permanently stop dividing while remaining metabolically active, first described by Leonard Hayflick and Paul Moorhead in 1961 as the limited replicative lifespan of cultured human cells, triggered by telomere shortening, DNA damage, oncogene activation in oncogene-induced senescence, and stresses in stress-induced premature senescence, with forms such as T-cell senescence in the immune system; senescent cells secrete inflammatory factors, the senescence-associated secretory phenotype, and are studied for roles in ageing, cancer suppression and age-related disease, including experimental senolytic drugs.

Why it exists Filled

Let an agent explain cellular senescence, relay mechanisms, biological roles and research directions from cell biology and ageing research sources with evidence attributed, describe the forms and causes the registry aliases name, avoid overstating anti-ageing claims, and distinguish senescence from apoptosis, quiescence and organismal ageing.

Distinguishing features Filled

  • Irreversible arrest
  • Secretory phenotype
  • Tumour suppression
  • Linked to ageing

What robots and AI may and may not do Filled

Must not

  • Present anti-ageing or senolytic treatments as proven for people.
  • Treat different causes of senescence, such as telomere shortening, as the same thing.
  • Advise a person to take senolytic drugs or supplements.

Only with a human decision

  • Any decision to use experimental anti-ageing treatment.

May

  • Explain cellular senescence, its discovery by Hayflick and Moorhead and its roles in ageing and disease.
  • Report research results with their stage, such as cell, animal or human studies.

Moral aspects Filled

  • Anti-ageing hype sells unproven products to hopeful people.
  • Research ethics apply to cell lines and the people they came from.

Who is affected

  • Consumers
  • Older people
  • Research participants

Owners Filled

Steward

Nobody owns the process; it belongs to biology as shared knowledge.

Identity and identifiers required Filled

  • Vercy registry: vr.tr.cellular-senescence

Plane ACT: no invented physical properties.

Recognition optional Filled

  • Permanent cell cycle arrest
  • T-cell senescence, stress-induced premature senescence, oncogene-induced senescence, telomere shortening
  • Apoptosis is cell death; quiescence is reversible arrest; organismal ageing is whole-body; telomere shortening is a cause

Capabilities and actions required Filled

  • explain mechanisms
  • relay roles in ageing and cancer
  • describe named forms
  • distinguish related processes

Hazards and failure modes required Filled

  • Overstating anti-ageing treatments
  • Treating causes such as telomere shortening as synonyms
  • Ignoring beneficial roles such as wound healing

Standards and interfaces required Filled

  • Clinical trial regulation for senolytic therapies

Context of use required Filled

  • Not applicable; a cell biological process.
  • replicative senescence
  • oncogene-induced senescence
  • stress-induced premature senescence
  • therapy-induced senescence
  • immunosenescence including T-cell senescence

Sources Filled

  1. Wikidata item Q9075999: cellular senescence - identity and sense of the item
  2. Wikipedia: Cellular senescence - general description of the item

Open questions

  • Should immunosenescence be a separate entry?
  • How should ageing research sources be linked?
  • The registry alias telomere shortening is a cause and should be recorded as a related process
