Incubation of MDCO-216 (ApoA-IMilano/POPC) with Human Serum Potentiates ABCA1-Mediated Cholesterol Efflux Capacity, Generates New Prebeta-1 HDL, and Causes an Increase in HDL Size

Figure 1

(a) and (b) Effect of MDCO-216 preincubated with 4% HSA (a) or with human serum (b) on global and ABCA1-mediated cholesterol efflux from J774 macrophages. Blue: basal efflux (efflux from cells not pretreated with cAMP), red bars: ABCA1-mediated efflux (additional efflux due to pretreatment of cells with cAMP). (c) The same data of (a) giving concentration of MDCO-216 (as protein) in the incubation medium of the efflux assay, compared with efflux induced by 20 μg/mL pure human wild-type apoA-I (uncomplexed) in the same run.
