Lipofuscin, Lipofuscin-Like Pigments and Autofluorescence
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.
متن کاملBone marrow lipofuscin.
Lipofuscins are commonly present in the macrophages of the marrow. In unstained preparations they may be confused with haemosiderin, but they are readily distinguished by fluorescence microscopy. In contrast to the belief that lipofuscins are a manifestation of senility, no age dependence has been demonstrated. Exceptionally large amounts have been found in illnesses accompanied by fever and le...
متن کاملGlycosylated hydroxytryptophan in a mussel adhesive protein from Perna viridis.
The 3,4-dihydroxyphenyl-l-alanine (Dopa)-containing proteins of mussel byssus play a critical role in wet adhesion and have inspired versatile new synthetic strategies for adhesives and coatings. Apparently, however, not all mussel adhesive proteins are beholden to Dopa chemistry. The cDNA-deduced sequence of Pvfp-1, a highly aromatic and redox active byssal coating protein in the green mussel ...
متن کاملUnderstanding RPE lipofuscin.
In the Research Highlight article titled ‘‘Rethinking A2E,’’ Smith et al. offer interpretations of the recent paper by Ablonczy et al., titled ‘‘Lack of Correlation Between the Spatial Distribution of A2E and Lipofuscin Fluorescence in the Human Retinal Pigment Epithelium.’’ Readers will benefit from further discussion. Although not acknowledged by Smith et al., RPE lipofuscin consists of multi...
متن کاملGlycosylated seryl residues in wall protein of elongating pea stems.
The protein content of salt-washed cell walls isolated from etiolated stems of Pisum sativum L. approximately doubled during elongation. In the same period the concentration in the wall of hydroxyproline, hydrazine-labile (= presumably glycosylated) serine, valine, tyrosine, lysine, and histidine increased markedly in comparison with other amino acids. After elongation was completed both the am...
