Injection of C57B1 mice with endotoxin or other bacterial antigens normally produces (i) a rise in the serum level of a factor that stimulates granulocyte and macrophage colony formation and (ii) a rise in the numbers of granulocyte and macrophage progenitors in the blood. Preinjection of the mice with polymerized flagellins of species specifically depressed both types of response. After a single injection of flagellin, depressed responsiveness began within 24 hr, persisted for several months and could be passively transferred to normal mice by injection of immune serum. Responsiveness was partially restored by 850 R whole body irradiation.
给C57B1小鼠注射内毒素或其他细菌抗原通常会导致:(i)刺激粒细胞和巨噬细胞集落形成的因子血清水平升高;(ii)血液中粒细胞和巨噬细胞祖细胞数量增加。预先给小鼠注射特定物种的聚合鞭毛蛋白会特异性地抑制这两种反应。单次注射鞭毛蛋白后,反应性降低在24小时内开始,持续数月,并且可以通过注射免疫血清被动转移到正常小鼠身上。850拉德的全身照射可部分恢复反应性。
