Abstract

A noncompetitive N-methyl-D-aspartate (NMDA) antagonist, MK-801 (0.5 to 2.0 mM), inhibits rabies virus infection in rat primary cortical neurons, whereas the competitive NMDA antagonist AP5 has no effect. The results suggest that MK-801-mediated inhibition of rabies virus replication, although selective, is not operating through the high-affinity binding site mechanism.

摘要

非竞争性N-甲基-D-天冬氨酸(NMDA)拮抗剂MK-801(0.5至2.0毫摩尔)可抑制大鼠原代皮质神经元中的狂犬病病毒感染,而竞争性NMDA拮抗剂AP5则无此作用。结果表明,MK-801介导的狂犬病病毒复制抑制作用虽然具有选择性,但并非通过高亲和力结合位点机制发挥作用。
