Abstract

We used a retroviral shuttle vector [pZIPNeoSV(X)] to transfect a monocyte-like murine tumour cell line (J774.G8) with the Mycobacterium leprae gene encoding heat-shock protein (hsp) 65. The antigen was expressed and presented on the surface of the transfected cell in association with major histocompatibility complex (MHC) class I and class II for recognition by T cells from specifically sensitized mice. We show here that when these transfected cells were used as a vaccine and introduced parentally into syngeneic (BALB/c) mice they conferred a remarkably high degree of protective immunity against subsequent challenge with either M. bovis bacillus Calmette-Guérin (BCG) or M. tuberculosis H37Rv.

摘要

我们使用逆转录病毒穿梭载体[pZIPNeoSV(X)],将编码热休克蛋白(hsp)65的麻风分枝杆菌基因转染至单核细胞样小鼠肿瘤细胞系(J774.G8)。该抗原得以表达,并与主要组织相容性复合体(MHC)I类和II类分子一起呈递于转染细胞表面,以供来自特异性致敏小鼠的T细胞识别。我们在此表明,当这些转染细胞用作疫苗并经腹腔注射引入同基因(BALB/c)小鼠时,它们能对随后用牛型结核分枝杆菌卡介苗(BCG)或结核分枝杆菌H37Rv进行的攻击赋予极高程度的保护性免疫。
