    GlossarySenescence-Associated Secretory Phenotype

    condition where aging cells release inflammatory molecules and enzymes

    Senescence-Associated Secretory Phenotype (SASP) refers to a condition where aging or damaged cells release a variety of inflammatory molecules, growth factors, and enzymes into their surroundings. This secretion can contribute to tissue dysfunction, chronic inflammation, and age-related diseases, including hair loss and alopecia, by affecting the local cellular environment and promoting further cellular damage.

      research Cellular Senescence: Ageing and Androgenetic Alopecia

      January 2023 in “Dermatology”
      The review "Cellular Senescence: Ageing and Androgenetic Alopecia" explores the connection between ageing and androgenetic alopecia (AGA), the most common type of hair loss characterized by the miniaturization of hair follicles. It highlights that beyond genetic and androgen factors, ageing and the associated increase in senescent cells play a significant role in AGA. The review discusses how androgen and oxidative stress-induced senescence mechanisms contribute to AGA and suggests potential therapeutic strategies. These strategies include inhibiting the senescence of dermal papilla cells (DPCs) and hair follicle stem cells (HFSCs), removing senescent cells, and reducing the senescence-associated secretory phenotype (SASP).
