Immature B cells obtained from the ileal Peyer's patches ( IPPs ) of sheep, upon exposure to phorbol myristate acetate (PMA), expressed 20-30 times more sIgM per cell than nonstimulated IPP cells, and the sIgM level was the same as that of peripheral B cells. The exposure of IPP cells to PMA also induced IgM secretion. Macrophages were not required for the terminal differentiation of IPP cells in vitro.
从绵羊回肠派尔集合淋巴结(IPP)获得的未成熟B细胞,在暴露于佛波酯(PMA)后,每个细胞表达的表面免疫球蛋白M(sIgM)比未刺激的IPP细胞多20 - 30倍,且sIgM水平与外周B细胞相同。IPP细胞暴露于PMA也会诱导IgM分泌。体外IPP细胞的终末分化不需要巨噬细胞。
