EB病毒(EBV)是一种疱疹病毒,其具有感染人B细胞并诱导它们分泌免疫球蛋白(IG)的能力。在目前的实验中,有限稀释培养物的泊松分析已用于研究EBV的B 95 -8株对人外周B细胞的活化。在所使用的培养条件下,0.2-1%的外周血B细胞被EBV激活以分泌IgM或IgG。此外,当检测含有有限数量B细胞的多个重复培养物的IgM和IgG产生时,IgM和IgG的前体独立分离;因此,单个B细胞前体成熟为分泌IgM或IgG的细胞,但不是两种类型的IG。进行使用EBV的有限稀释的额外实验以研究B细胞活化的病毒要求。这些研究表明,EBV激活B细胞产生IG与“一击”模型一致,与“两击”模型不一致。总之,这些结果表明,一种EBV病毒粒子的感染足以诱导前体外周血B细胞分泌IG,然后仅分泌一种同种型的IG。
The Epstein-Barr virus (EBV) is a herpes virus that has the capacity to infect human B cells and to induce them to secrete immunoglobulin (Ig). In the current experiments, Poisson analysis of limiting dilution cultures has been used to study the activation of human peripheral B cells by the B95-8 strain of EBV. Under the culture conditions used, 0.2-1% of peripheral blood B cells were activated by EBV to secrete IgM or IgG. In addition, when multiple replicate cultures containing limited numbers of B cells were tested for IgM and for IgG production, the precursors for IgM and IgG segregated independently; thus, individual B cell precursors matured into cells secreting IgM or IgG but not both classes of Ig. Additional experiments using limiting dilutions of EBV were undertaken to study the viral requirements for B cell activation. These studies indicated that B cell activation by EBV to produce Ig was consistent with a "one-hit" model and inconsistent with a "two-hit" model. Taken together, these results indicate that infection by one EBV virion is sufficient to induce a precursor peripheral blood B cell to secrete Ig and that only one isotype of Ig is then secreted.
