Abstract

A female F344 rat was injected with 2.4 x 10(6) MT-2 cells intravenously at 3 and 4 weeks old, and was mated with a non-infected male rat at the 17th week after injection, when the dam rat contained HTLV-1 provirus in the peripheral blood mononuclear cells as determined by polymerase chain reaction. HTLV-1 provirus was detected in at least 2 out of 9 offspring. This system should be useful for studies on the routes and prevention of vertical transmission and on elimination of once-transmitted HTLV-1.

摘要

一只雌性F344大鼠在3周龄和4周龄时经静脉注射了2.4×10⁶个MT - 2细胞,并在注射后第17周与一只未感染的雄性大鼠交配,此时通过聚合酶链反应测定发现母鼠外周血单核细胞中含有HTLV - 1前病毒。在9只后代中至少有2只检测到HTLV - 1前病毒。该系统对于研究垂直传播的途径和预防以及消除一旦传播的HTLV - 1应该是有用的。
