用Nb 2淋巴结淋巴瘤生物测定和免疫染色法测定伴刀豆球蛋白A激活的小鼠脾单核细胞(脾细胞)培养上清液中催乳素样分子的含量。Con A刺激的脾细胞产生一种具有催乳素样免疫反应性的因子,该因子对Nb 2淋巴瘤细胞具有促有丝分裂作用。该因子首先出现在淋巴细胞有丝分裂发生的培养上清液中,其活性与培养的细胞数成正比。此外,大鼠催乳素抗血清可抑制脾细胞增殖,并且添加激素可部分逆转这种抑制作用。这些研究结果表明,小鼠脾细胞产生催乳素样活性的物质,并建议这种因素是淋巴细胞增殖所必需的。
Culture supernanants from concanavalin A activated murine splenic mononuclear cells (splenocytes) were assayed for prolactin-like molecules using the Nb2node lymphoma bioassay and immunostaining procedures. Con A stimulated splenocytes produced a factor with prolactin-like immunoreactivity that was mitogenic for Nb2lymphoma cells. This factor first appeared in culture supernatants with the onset of lymphocyte mitogenesis and its activity was proportional to the number of cells cultured. In addition, splenocyte proliferation was inhibited by antiserum to rat prolactin, and this inhibition was partially reversed by added hormone. These findings show that murine splenocytes produce a substance with prolactin-like activity and suggest that this factor is essential for lymphocyte proliferation.
