人類 T 淋巴細胞病毒 1 型 HTLV-1 Tax (11-1)，LLFGYPVYV，是一種免疫顯性 HLA-A2 限制性表位。它被 HTLV-1 相關脊髓病/熱帶痙攣性下肢輕癱 (HAM/TSP) 患者的大量 CD8? 細胞毒性 T 淋巴細胞 (CTL) 識別，這是一種與 HTLV-1 感染相關的脫髓鞘炎性神經系統(tǒng)疾病。因此，LLFGYPVYV 是闡明抗原特異性 CD8? CTL 在 HAM/TSP 中作用的有用工具。

Human T lymphotropic virus type 1 HTLV-1 Tax (11-1), LLFGYPVYV, is an immunodominant HLA-A2-restricted epitope. It is recognized by a high number of CD8? cytotoxic T lymphocytes (CTLs) in patients with HTLV-1-associated myelopathy/tropical spastic paraparesis (HAM/TSP), a demyelinating inflammatory neurologic disease associated with HTLV-1 infection. LLFGYPVYV therefore represents a useful tool to elucidate the role of antigen-specific CD8? CTLs in HAM/TSP.
