    • This invention relates to lymphotoxin-.beta., a lymphocyte membrane type protein. This protein is found on the surface of a number of cells, including phorbol ester (PNA) stimulated T cell hybridoma II-23.D7 cells. This invention also relates to complexes formed between lymphotoxin-.beta. and other peptides such as lymphotoxin-.alpha. and to complexes comprising multiple subunits of lymphotoxin-.beta.. These proteins and complexes are useful in holding LT-.alpha. formed within the cell on the cell surface where the LT-.alpha./LT-.beta. complex may act as an inflammation regulating agent, a tumor growth inhibiting agent, a T cell inhibiting agent, a T cell activating agent, an autoimmune disease regulating agent, or an HIV inhibiting agent. Furthermore, the antitumor activity of the LT-.alpha./LT-.beta. complex may be delivered to tumor cells by tumor infiltrating lymphocytes (TILs) transfected with the gene for LT-.beta..
    • 本发明涉及淋巴细胞膜型蛋白质淋巴细胞毒素-β。 这种蛋白质在许多细胞的表面发现,包括佛波酯(PNA)刺激的T细胞杂交瘤II-23.D7细胞。 本发明还涉及在淋巴毒素-β和其它肽如淋巴毒素-α之间形成的复合物以及包含淋巴毒素-β的多个亚基的复合物。 这些蛋白质和复合物可用于保持在细胞表面上形成的LT-α,其中LT-α/ LT-β复合物可以作为炎症调节剂,肿瘤生长抑制剂,T细胞抑制剂, T细胞活化剂,自身免疫疾病调节剂或HIV抑制剂。 此外,LT-α/ LT-β复合物的抗肿瘤活性可通过用LT-β基因转染的肿瘤浸润淋巴细胞(TIL)递送至肿瘤细胞。
