血清淀粉样蛋白A(SAA)是反应性淀粉样蛋白沉积中纤维成分(AA蛋白)的血清前体,是一种多基因产物。血清中显著的急性期同型SaA I,也是主要的纤维前体,具有多个等位基因变异。在日本,三个主要等位基因(1.1、1.3和1.5)中的每一个出现的频率大致相同。最近的研究表明,等位基因1.5对血清SAA浓度有正向影响。为了阐明这一点,本研究在大肠杆菌表达系统中表达了重组人SAA I.1、SAA I.3和SAA I.5,并将这些重组高密度脂蛋白注射到小鼠体内检测血浆清除率。SAA1.5从血浆中消失的速度比其他两种IS型要慢。这可能是等位基因1.5对血清SAA浓度有正向影响的原因。
Serum amyloid A (SAA), the serum precursor of the fibrillar component (AA proteins) in reactive amyloid deposits, is a multigene product. SAA I, the prominent acute phase isotype in serum and also the dominant fibril precursor, has several allelic variants. In Japan, each of the three major alleles (1.1, 1.3 and 1.5) appears with approximately equal frequency. Recent research suggested that allele 1.5 has a positive influence on the serum SAA concentration. To clarify this, in the present study recombinant human SAA I.1, SAA I.3 and SAA I.5 were produced in an E. coli expression system and those species of reconstituted high density lipoprotein were injected into mice to examine plasma clearance. SAA 1.5 disappeared from plasma more slowly than the other two is types. This may account for the positive influence of allele 1.5 on the serum SAA concentration.
