In an attempt to induce circulating interferon (IFN) chronically, C57BL/6 or Balb/cBy mice received daily injections or continuous infusion of polyriboinosinic:polyribocytidilic acid [poly(I:C)] i.p. for 7 days. Significantly higher plasma IFN was present in C57BL/6 mice receiving poly(I:C) via continuous infusion compared with daily injections. Spleen and bone marrow natural killer (NK) cells were elevated only in the group receiving poly(I:C) continuously. Little IFN was induced acutely in Balb/cBy mice and none was present after chronic infusion of poly(I:C). NK cells were not elevated. Continuous infusion of poly(I:C) appears to overcome the hyporesponsiveness to repeated IFN induction in a susceptible mouse strain.
为了长期诱导循环干扰素(IFN),C57BL/6或Balb/cBy小鼠腹腔内每日注射或持续输注聚肌苷酸:聚胞苷酸[poly(I:C)],持续7天。与每日注射相比,通过持续输注接受聚(I:C)的C57BL/6小鼠血浆IFN显著更高。仅在持续接受聚(I:C)的组中,脾脏和骨髓自然杀伤(NK)细胞有所升高。Balb/cBy小鼠急性诱导产生的IFN很少,慢性输注聚(I:C)后则没有IFN。NK细胞没有升高。持续输注聚(I:C)似乎克服了易感小鼠品系对重复IFN诱导的低反应性。
