【摘要】:正人類免疫球蛋白G4(Immunoglobulin G4,Ig G4)是Ig Gs的亞型。Ig Gs在初次免疫應(yīng)答中被較遲分泌,在二次免疫應(yīng)答中被記憶B細(xì)胞大量分泌。Ig Gs依據(jù)重鏈序列、鉸鏈區(qū)長度及鏈間二硫鍵連接位置和數(shù)目的差異,被分為Ig G1、Ig G2、Ig G3和Ig G4[1]。健康個(gè)體Ig G4血漿濃度僅為0.08~1.4mg/ml,Ig G4/Ig G比值為0.8%~11.7%。Ig G4因多個(gè)特點(diǎn)成為研究的熱點(diǎn)。首先在體內(nèi),Ig G4能持續(xù)地和其他Ig G4進(jìn)行半分子交換。
[Abstract]:Immunoglobulin G _ 4 G _ 4) is the subtype of IgG Gs. Ig Gs are secreted late in the primary immune response, and are secreted by memory B cells in large quantities by memory B cells in the secondary immune response, according to the heavy chain sequence, the immunoglobulin G _ 4 is a subtype of immunoglobulin G _ 4 and immunoglobulin G _ 4 is secreted late in the primary immune response. The differences in the length of the hinge area and the position and number of disulfide bond connections between chains, The plasma concentration of Ig G4 in healthy individuals was only 0.08 鹵1.4 mg / ml Ig G4 / Ig G4 / Ig G4 / Ig G4 / Ig G4 / Ig G4 / Ig G4 / Ig G4 / Ig G4 / Ig G4 / Ig G4 / Ig G4 / Ig G4 / Ig G4 / Ig G4 / Ig G4 / Ig G4 / Ig G4 / Ig G4 / Ig G4 / Ig G4 / Ig G4 / Ig G4 / Ig G4 / Ig G4 / Ig G4 / Ig G4
