Abstract

Antilymphocyte serum was prepared in several species and its effect on the production of migration inhibitory factor (MIF) studied. Antilymphocyte sera in dilutions as high as 1/3200 inhibited the liberation of MIF by sensitized lymphocytes in the presence of antigen. In contrast antipolymorph and antiglobulin sera were inactive. Antilymphocyte serum also blocked the formation of MIF when the lymphocytes were preincubated with ALS and then washed before the addition of antigen. The antilymphocyte serum and sera prepared against supernatants containing MIF did not block MIF activity by direct neutralization.

摘要

在多个物种中制备了抗淋巴细胞血清,并研究了其对迁移抑制因子(MIF)产生的影响。稀释至1/3200的抗淋巴细胞血清在有抗原存在的情况下可抑制致敏淋巴细胞释放MIF。相比之下,抗多形核白细胞血清和抗球蛋白血清则无活性。当淋巴细胞先用抗淋巴细胞血清预孵育,然后在加入抗原前洗涤时,抗淋巴细胞血清也会阻断MIF的形成。抗淋巴细胞血清和针对含有MIF的上清液制备的血清不会通过直接中和作用阻断MIF活性。
