OBJECTIVES
To provide an ultimate understanding of the anti-atherogenic role of plasma HDL (high density lipoprotein) by defining how HDL structure and metabolism affect intravascular and extravascular cholesterol redistribution. This aim is being achieved by the use of model and native lipoprotein particles to define the physical-chemical and metabolic bases for speciation of nascent and plasma apolipoprotein-specific high density lipoproteins; by examination of the remodeling analogs of nascent HDL resulting from their interaction with plasma lipoproteins and how phospholipid species, cholesterol, and lipolysis-derived products may modulate the remodeling process; and by the use of apo-specific analogs to nascent HDL and plasma apo-specific HDL to determine the influence of compositional factors on cholesterol efflux from cells.
METHODOLOGY
Human serum collected under another project (LBNL-79-106-H02) is used as the source for isolation of lipoproteins, proteins and enzymes used in the research described above. In donating blood under the source project, the subject experiences the risks common to clinical venipuncture (possible bruising, remote chance of infection). The Alameda-Contra Costa County blood bank serves as an additional source of blood plasma.
