摘要: Neuromelanin and lipofuscin are two pigments produced within the human brain that, until recently, were considered inert cellular waste products of little interest to neuroscience. Recent research has increased our understanding nature interactions these with their environment suggests that may, indeed, influence function. The physical appearance distribution differ, but both accumulate in aging share some structural features. Lipofuscin accumulation been implicated postmitotic cell aging, while neuromelanin is suggested function as an iron-regulatory molecule possible protective functions cells which produce this pigment. This review presents comparative aspects biology lipofuscin, well a discussion hypothesized roles neurodegenerative disease.
