Células zombis: el "veneno" biológico que acelera tu envejecimiento sin que lo sepas
Puede sonar a ciencia ficción, pero en nuestro cuerpo habitan auténticos «zombis». No caminan ni gruñen, pero sí dañan silenciosamente nuestros tejidos. […]
TL;DR
- Senescent cells, nicknamed 'zombie cells,' are live cells that have stopped dividing but persist, releasing inflammatory substances.
- These cells contribute to 'inflammaging,' a low-grade chronic inflammation linked to cardiovascular diseases, neurodegeneration, diabetes, and arthritis.
- The immune system's declining ability to clear senescent cells with age leads to their accumulation in various tissues, weakening the body.
- Senescence originally serves as a defense against cancer and aids in wound healing, but chronic presence becomes detrimental.
- Senolytics are compounds designed to selectively eliminate harmful senescent cells without affecting healthy ones.
- Interest is growing in natural senolytics derived from everyday foods, moving beyond experimental drugs.
