B族链球菌(GBS)感染在婴儿中引起显著的死亡率和发病率。被动抗体免疫疗法已被提议作为感染婴儿的治疗。为此,通过人B细胞的EBV永生化产生两种人mAb分泌细胞系。通过ELISA和交叉免疫电泳证明,mAb对B组多糖具有特异性,并与所有五种血清型的菌株结合。mAb反应并调理了100%(132/132)的检测临床分离株,代表了所有4种胶囊类型。这些单克隆抗体的预防性和治疗性保护作用在新生大鼠中得到证实,这些新生大鼠被Ia型和III型人类临床分离株致死性感染。这些数据表明,针对B族碳水化合物的单一人mAb可以保护免受由不同血清型引起的GBS感染。这种抗体可能是有用的被动免疫治疗婴儿感染GBS。
Group B streptococcal (GBS) infections cause significant mortality and morbidity among infants. Passive antibody immunotherapy has been proposed as treatment for infected infants. To this end, two human mAb- secreting cell lines were produced by EBV immortalization of human B cells. The mAbs were specific for the group B polysaccharide and bound to strains of all five serotypes as demonstrated by ELISA and crossed immunoelectrophoresis. The mAbs reacted and opsonized 100% (132/132) of the clinical isolates tested which represented all four capsule types. Both prophylactic and therapeutic protection with these mAbs were demonstrated in neonatal rats given lethal infections of types Ia and III human clinical isolates. These data indicate that a single human mAb directed against the group B carbohydrate can protect against GBS infections caused by the different serotypes. This antibody may be useful in the passive immunotherapy of infants infected with GBS.
