Interleukin 10 (IL-10), originally identified as a TH2 helper T-cell product able to inhibit cytokine production by TH1 cells, is highly homologous to BCRF1 (viral IL-10), an open reading frame in the Epstein-Barr virus genome. Here, we show that human and viral IL-10 stimulate DNA replication of B lymphocytes activated either via their antigen receptor or via their CD40 antigen. IL-4 and IL-10 display additive effects and induce a strong increase in the number of viable cells. Moreover, IL-10 induces activated B cells to secrete large amounts of IgG, IgA, and IgM, and the combination of IL-10 and IL-4 results in the secretion of the four immunoglobulin isotypes. Thus, IL-10 may play an important role in the amplification of humoral responses.
白细胞介素10(IL-10)最初被鉴定为一种能够抑制TH1细胞产生细胞因子的TH2辅助性T细胞产物,它与EB病毒基因组中的一个开放阅读框BCRF1(病毒IL-10)高度同源。在此,我们表明人和病毒IL-10可刺激通过其抗原受体或通过其CD40抗原激活的B淋巴细胞的DNA复制。IL-4和IL-10显示出相加效应,并诱导活细胞数量大幅增加。此外,IL-10诱导活化的B细胞分泌大量的IgG、IgA和IgM,并且IL-10与IL-4的组合导致四种免疫球蛋白同种型的分泌。因此,IL-10可能在体液免疫反应的放大中起重要作用。
