Fine tuning of cell functions through remodeling of glycosphingolipids by plasma membrane-associated glycohydrolases.

abstract：:Small organic molecules, like Congo red and lacmoid, have been shown to modulate the self-assembly of the amyloid β peptide (Aβ). Here, we show that Aβ forms NMR invisible non-toxic co-aggregates together with lacmoid as well as Congo red. We find that the interaction involves two distinct kinetic processes and at eve...
