The possibility was investigated of using frozen stocks of phytohemagglutinin (PHA)-stimulated normal human peripheral blood lymphocytes (PBL) in cocultivation with human immunodeficiency virus (HIV)-infected lymphocytes for the isolation of HIV. Fresh and cryopreserved PBL from eight healthy volunteers were compared for their susceptibility to HIV infection in vitro. Fresh lymphocytes, as well as lymphocytes that were stimulated with PHA before or after cryopreservation, displayed comparable susceptibilities to HIV infection in vitro. In addition, HIV was recovered in all cases when lymphocytes stimulated with PHA before or after cryopreservation were cocultured in parallel with PBL from 15 patients with acquired immune deficiency syndrome. However, the cryopreserved PBL were less efficient in isolating HIV from asymptomatic men.
研究了使用冷冻保存的植物血凝素(PHA)刺激的正常人外周血淋巴细胞(PBL)与人类免疫缺陷病毒(HIV)感染的淋巴细胞共培养以分离HIV的可能性。比较了来自8名健康志愿者的新鲜和冷冻保存的PBL在体外对HIV感染的易感性。新鲜淋巴细胞以及在冷冻保存之前或之后用PHA刺激的淋巴细胞在体外对HIV感染表现出相当的易感性。此外,当将冷冻保存之前或之后用PHA刺激的淋巴细胞与15例获得性免疫缺陷综合征患者的PBL平行共培养时,在所有情况下都能回收HIV。然而,冷冻保存的PBL从无症状男性中分离HIV的效率较低。
