The MT-4 human T-cell line expresses HTLV-1 Tax and is permissive for replication of an HIV-1 gp41 mutant lacking the cytoplasmic tail. MT-4 cells (lot 150048), distributed by the NIH AIDS Reagent Program (NIH-ARP), were found to be Tax deficient and unable to host replication of the gp41-truncated HIV-1 mutant. These findings, together with short tandem repeat profiling, established that lot 150048 are not bona fide MT-4 cells.

美国国立卫生研究院艾滋病试剂计划分发的MT-4细胞的鉴定分析。

MT-4人类T细胞系表达HTLV-1税收，并且允许复制缺少细胞质尾巴的HIV-1 gp41突变体。NIH AIDS试剂计划（NIH-ARP）分发的MT-4细胞（批次150048）被发现缺乏税，并且无法宿主gp41截短的HIV-1突变体的复制。这些发现以及较短的串联重复序列分析证明，批次150048不是真正的MT-4细胞。
