Abstract

Anti-2,4-dinitrophenyl (DNP) IgE producing hybridoma B 53 when injected subcutaneously is established equally well in syngeneic BALB/c (heavy-chain allotype a) and congenic CB20 (heavy-chain allotype b) mice. However, secretion of anti-DNP IgE monoclonal antibody is greatly suppressed in CB20 mice. B 53 cells taken from the subcutaneous tumors of CB20 mice produce anti-DNP IgE in vivo in BALB/c mice and in vitro. No difference was observed in IgE production between these cells and the controls taken from BALB/c mice. The suppression of IgE production was due to T cells and/or their product(s) of CB20 mice.

摘要

产生抗2,4 - 二硝基苯基(DNP)IgE的杂交瘤B 53皮下注射时,在同基因的BALB/c(重链同种异型a)和同类系CB20(重链同种异型b)小鼠中生长情况相同。然而,CB20小鼠中抗DNP IgE单克隆抗体的分泌受到极大抑制。取自CB20小鼠皮下肿瘤的B 53细胞在BALB/c小鼠体内及体外均能产生抗DNP IgE。这些细胞与取自BALB/c小鼠的对照细胞在IgE产生方面未观察到差异。IgE产生的抑制是由于CB20小鼠的T细胞和/或其产物。
