Heparanases

WebIn conclusion, our study reveals details of the behavior of both heparanases in AD, pointing to the combined overexpression of HPSE and HPSE2, mostly related to AD pathology. While HPSE activity would seem to either release Aβ deposits or block tau intracellular fibril formation and propagation, HPSE2 appears to act as an inhibitor of HPSE.

At the extracellular level, HPSE was observed only in neuritic plaques with a fragmented core, while HPSE2 appeared in those with compact cores as well. Web1 mag 2007 · Mammalian heparanases are endoglycosidases that cleave heparin/HS chains at specific intrachain sites. The first report on heparanases goes back to 1975, when Ögren and Lindahl described an endoglucuronidase from mouse mast cells, capable of cleaving macromolecular heparin at a limited number of sites [ 50 ].
