Lipofuscin, lipofuscin-like pigments and autofluorescence

Abstract

A brief overview is here provided on lipofuscin and lipofuscin-like substances, with particular reference to their biological significance as well as to their cellular origin and pathophysiological role. Special emphasis is also placed on the mutual relationships between lipofuscin and lipofuscin-like lipopigments on one side, and cell autofluorescence on the other.
