Using thrombin and trypsin as probes, we determined: first, that low-density lipoprotein (LDL) receptor binding determinants switch from apolipoprotein (apo) E to apo-B within the very-low-density lipoprotein (VLDL) Sf 20-60 region of the metabolic cascade from VLDL1 (Sf 100-400) of hypertriglyceridemic (HTG) human subjects to LDL. Second, two different(More)
Indoleamine 2, 3-dioxygenase (IDO) is a rate-limiting enzyme for the tryptophan catabolism. In human and murine cells, IDO inhibits antigen-specific T cell proliferation in vitro and suppresses T cell responses to fetal alloantigens during murine pregnancy. In mice, IDO expression is an inducible feature of specific subsets of dendritic cells (DCs), and is(More)
Murine P388D1 macrophages have a receptor pathway that binds human hypertriglyceridemic very low density lipoproteins (HTG-VLDL) that is fundamentally distinct from the LDL receptor pathway. Trypsin-treated HTG-VLDL (tryp-VLDL), devoid of apolipoprotein (apo)-E, fail to bind to the LDL receptor, yet tryp-VLDL and HTG-VLDL cross-compete for binding to P388D1(More)
