Laurdan (6-dodecanoyl-2-dimethylamine-naphthalene) is a fluorescent membrane probe of recent characterization. It was shown that this probe discriminates between phase transitions, phase fluctuations and the coexistence of phase domains in phospholipid multilamellar aggregates. We measured the excitation and emission generalized polarization

Recent studies have shown that pharmacological increases in HDL cholesterol concentrations do not necessarily translate into clinical benefits for patients, raising concerns about its predictive value for cardiovascular events. Here we hypothesize that the size-modulated lipid distribution within HDL particles
