Abstract

Fusion between P3 x 63 Ag8 mouse myeloma cells and spleen cells from BALB/c mice immunized with influenza type A or B or parainfluenza type 1 virus generated reproducibly antiviral antibody-producing somatic cell hybrids (hybridomas). Eleven hybridomas derived from spleen cells of mice immunized with influenza type A virus were directed against the viral hemagglutinin, one reacted with a host component derived from chickens, and one expressed a specificity not further characterized. The hybridoma antibodies tended to be highly specific for the hemagglutinin of the immunizing virus and seemed to express the same repertoire of strain-specific antibody reactivities as splenic precursor B cells, they did not express any of the frequently occurring crossreactive anti-hemagglutinin specificities. Hybridomas producing crossreactive antibodies against hemagglutinin could be obtained if priming and boosting virus were heterologous.

摘要

将P3 x 63 Ag8小鼠骨髓瘤细胞与用甲型或乙型流感病毒或1型副流感病毒免疫的BALB/c小鼠的脾细胞进行融合,可重复性地产生抗病毒抗体的体细胞杂种(杂交瘤)。从用甲型流感病毒免疫的小鼠脾细胞中获得的11个杂交瘤针对病毒血凝素,1个与来源于鸡的宿主成分发生反应,1个表现出未进一步鉴定的特异性。杂交瘤抗体往往对免疫病毒的血凝素具有高度特异性,并且似乎表达与脾前体B细胞相同的菌株特异性抗体反应谱,它们不表达任何常见的交叉反应性抗血凝素特异性。如果初次免疫和加强免疫的病毒是异源的,则可以获得产生针对血凝素的交叉反应性抗体的杂交瘤。
