CD5 (Ly-1) B cells are a minor subpopulation in mouse spleen and are thought to be responsible for the production of natural autoantibodies to bromelain-treated autologous erythrocytes (Br-RBC). Here it is shown that substantial numbers of conventional, CD5-negative, splenic B cells also secrete these antibodies in CBA and (NZB x NZW)F1 mice, whereas in NZB and BALB/c mice they are all produced by the CD5 B-cell population. However, stimulation with bacterial lipopolysaccharide in vivo preferentially activates the CD5 B-cell group to anti-Br-RBC antibody secretion.
CD5(Ly-1)B细胞是小鼠脾脏中的一个次要亚群,被认为负责产生针对菠萝蛋白酶处理的自体红细胞(Br-RBC)的天然自身抗体。本文表明,在CBA和(NZB×NZW)F1小鼠中,大量传统的、CD5阴性的脾脏B细胞也分泌这些抗体,而在NZB和BALB/c小鼠中,它们均由CD5 B细胞群体产生。然而,体内用细菌脂多糖刺激可优先激活CD5 B细胞群体分泌抗Br-RBC抗体。
