Objective—The purpose of this study was to investigate the interaction of SAA and SR-BI in remodeling of acute phase HDL (AP HDL). Methods and Results—We used SAA and SR-BI adenoviral vector expression models to study the interaction between these entities. SR-BI processing of mouse AP HDL generated progressively smaller discreet HDL particles with distinct apolipoprotein compositions. SR-BI ac...

Serum amyioid A (SAA) 1 is presumed to be the precursor for amyloid A protein, the main protein constituent found in the amyioid fibrils of reactive amyloidosis (1-3). In the mouse SAA is encoded by a family of three genes (Morrow, John F., personal communication). SAA1 and SAA2 are synthesized in the liver by hepatocytes (4-10) and are found circulating in nearly equal quantities associated wi...

Serum amyloid A apol ipoprote in family consists of three members that in human beings are coded by different genes: SAA1, SAA2, and SAA4 (reviewed in 1-3). SAA1 and SAA2 are so-called acute phase isoforms. Their expression is increased in response to inflammation. SAA4 is a constitutive isoform, the expression of which does not change during an acute-phase response. In addition, one more relat...

Abstract Repulsive electrostatic forces between prion‐like proteins are a barrier against aggregation. In neuropharmacology, however, prion's net charge ( Z ) is not targeted parameter. Compounds that selectively boost prion remain unreported. Here, we synthesized compounds amplified the negative of misfolded superoxide dismutase‐1 (SOD1) by acetylating lysine‐NH 3 + in amyloid‐SOD1, without na...

S100A12 is elevated in the circulation in patients with chronic inflammatory diseases and recent studies indicate pleiotropic functions. Serum amyloid A induces monocyte cytokines and tissue factor. S100A12 did not stimulate IL-6, IL-8, IL-1β or TNF-α production by human peripheral blood mononuclear cells but low amounts consistently reduced cytokine mRNA and protein levels induced by serum amy...
