我们利用一种针对人类T细胞白血病病毒I型(HTLV‐I)反式激活子(tax1)抗原的单克隆抗体Lt‐4,通过免疫荧光和免疫印迹检测了多种携带HTLV‐I和相关逆转录病毒、类人猿T细胞白血病病毒I型(STLV‐I)和HTLV‐II的T细胞系中tax1和相关抗原的表达。Lt‐4与所有携带HTLV‐I的细胞系和携带STLV‐I的8个猿类细胞系中的5个发生反应,但与携带HTLV‐II的细胞系不发生反应。Lt‐4在大多数HTLV‐I细胞系中检测到40 kd tax1抗原分子,除了一个表达39 kd tax1抗原的细胞系。在携带STLV‐I的T细胞系中,Lt‐4检测到的tax1相关抗原分子是异质的,分子量在36-41 kd之间。
Using a monoclonal antibody, Lt‐4, directed against human T cell leukemia virus type I (HTLV‐I) trans‐activator (tax1) antigen, we examined the expression of tax1 and related antigens in a variety of T cell lines bearing HTLV‐I and related retroviruses, simian T cell leukemia virus type I (STLV‐I) and HTLV‐II, by immunofluorescence and immunoblot assays. Lt‐4 reacted with all HTLV‐I‐bearing cell lines tested and five out of eight simian cell lines bearing STLV‐I, but not with an HTLV‐II‐bearing cell line. Lt‐4 detected 40 kd tax1 antigen molecules in most HTLV‐I‐bearing cell lines except one cell line that expressed 39 kd tax1 antigen. In the STLV‐I‐bearing T cell lines, tax1‐related antigen molecules detected by Lt‐4 were heterogeneous, having molecular weights in the range of 36–41 kd.
