lipofisen
Lipofuscin is a yellowish-brown pigment that accumulates in the cytoplasm of various cells, particularly in post-mitotic cells such as neurons and cardiomyocytes. It is often referred to as the "age pigment" because its concentration increases with age. Lipofuscin is composed of oxidized lipids and proteins, believed to be the result of the cellular process of autophagy, where damaged organelles and molecular components are degraded. These components, when not fully cleared, aggregate over time.
The accumulation of lipofuscin is considered a marker of cellular aging and oxidative stress. While generally
