In this report we describe the characterization of the immunomodulatory efficiency and therapeutic properties of thymosin fraction five (F5). We consistently observed the immunostimulation of T-cell activity in assays of allogeneic mixed lymphocyte response (MLR) and the development of cytotoxic effector cells in an allogeneic mixed lymphocyte tumor response-cell-mediated cytotoxicity assay (MLTR-CMC). No induction of suppressor cell activity was observed. Thymosin F5 also acted successfully as an adjuvant when admixed with irradiated tumor cells. We were unable to demonstrate either NK cell or macrophage activation by thymosin F5. Therapeutic protocols using thymosin F5 and directed against pre-existing experimental and spontaneous metastases, had a significant immunotherapeutic potential.
在本报告中,我们描述了胸腺素组分五(F5)的免疫调节效率和治疗特性。在异体混合淋巴细胞反应(MLR)试验中,我们始终观察到T细胞活性的免疫刺激作用,并且在异体混合淋巴细胞肿瘤反应-细胞介导的细胞毒性试验(MLTR-CMC)中观察到细胞毒性效应细胞的产生。未观察到抑制细胞活性的诱导。当与经照射的肿瘤细胞混合时,胸腺素F5也成功地起到了佐剂的作用。我们未能证明胸腺素F5对NK细胞或巨噬细胞有激活作用。使用胸腺素F5并针对预先存在的实验性和自发性转移瘤的治疗方案具有显著的免疫治疗潜力。
