Heparan sulfate dissociates serum amyloid A (SAA) from acute-phase high-density lipoprotein, promoting SAA aggregation.
Inflammation-related (AA) amyloidosis is a severe clinical disorder characterized by the systemic deposition of the acute-phase reactant serum amyloid A (SAA). SAA is normally associated with the high-density lipoprotein (HDL) fraction in plasma, but under yet unclear circumstances, the apolipoprotein is converted into amyloid fibrils. AA amyloid and heparan sulfate (HS) display an intimate rel...
متن کاملHuman Serum Amyloid A3 (SAA3) Protein, Expressed as a Fusion Protein with SAA2, Binds the Oxidized Low Density Lipoprotein Receptor
Serum amyloid A3 (SAA3) possesses characteristics distinct from the other serum amyloid A isoforms, SAA1, SAA2, and SAA4. High density lipoprotein contains the latter three isoforms, but not SAA3. The expression of mouse SAA3 (mSAA3) is known to be up-regulated extrahepatically in inflammatory responses, and acts as an endogenous ligand for the toll-like receptor 4/MD-2 complex. We previously r...
متن کاملSecretion of serum amyloid protein and assembly of serum amyloid protein-rich high density lipoprotein in primary mouse hepatocyte culture.
The serum amyloid protein (apo-SAA) is a unique high density lipoprotein apoprotein exhibiting dramatic increases in plasma concentration following host injury. The events involved in the secretion of apo-SAA and assembly of apo-SAA-rich lipoprotein particles were studied in primary, serum-free culture of adult BALB/c mouse hepatocytes harvested 3 h following administration of the potent apo-SA...
متن کاملThe acute phase protein serum amyloid A primes neutrophils.
We studied here the effect of the acute phase protein serum amyloid A (SAA) on the oxidative burst of neutrophils. Incubation of neutrophils with SAA increased the rate of oxygen uptake and the production of reactive oxygen species of neutrophils activated with opsonized zymosan (OZ). The increment in the neutrophil oxidative burst was dependent on SAA concentration in the range of 3-33 microg ...
