Apolipoprotein D (apoD) is a small glycoprotein responsible for the local transport of small hydrophobic ligands. Within the nervous system, apoD may be an acute phase protein that is upregulated in a variety of neuropathological conditions and is involved in the removal of lipids during nerve cell degeneration and provision of lipids during the(More)
We have previously shown that plasma lipoproteins can be separated by analytical capillary isotachophoresis (ITP) according to their electrophoretic mobility in a defined buffer system. As in lipoprotein electrophoresis, HDL show the highest mobility followed by VLDL, IDL, and LDL. Chylomicrons migrate according to their net-charge between HDL and VLDL,(More)
The serum amyloid A (SAA) superfamily comprises a number of differentially expressed genes with a high degree of homology in mammalian species. SAA4, an apolipoprotein constitutively expressed only in humans and mice, is associated almost entirely with lipoproteins of the high-density range. The presence of SAA4 mRNA and protein in macrophage-derived foam(More)
It has been found that the capacity of lipoproteins for binding Mn(II) ions is dependent on the arrangement of the lipoprotein core. A change in the molecular organization of the LDL core (thermotropic transition) is associated with the change on the lipoprotein surface. In HDL there is no thermotropic transition and no abrupt change of the binding(More)
