AntiーCD3 Monoclonal Antibody and IL-2 Induced Cytotoxicity of T Lymphocytes from Oral Cancer Patients.

一个大的细胞数量，细胞毒性活动水平高的地方，被要求用淋巴素激活的杀手（LAT）细胞进行成功的接受免疫治疗。我们试图用抗CD 3单克隆抗体和干扰素-2培养CD 3-ALK细胞，并研究了如何对ALK细胞（CD 3·ALK）产生积极反应和细胞毒性活动的影响（细胞因子，OK 432等）。在临床上，辐射疗法、化学疗法和适应性免疫疗法组合的治疗效应是预期的，因此，我们调查了这些疗法对CD 3-LAT细胞的影响。CD 3·LAK细胞的诱导：使用抗CD 3单克隆抗体和IL-2.2的抗CD 3单克隆抗体和IL-2.2诱导的高增殖反应和细胞毒性活动。细胞因子（rIFNgamma， rTNF alpha， rG-CSF，rIL-1alpha，rIL-1beta）对CD 3·LAKcell：CD 3的Proliferative响应·rTNalpha对rIL-2低浓度的LAKcell。这些细胞的细胞毒性活动并不受任何细胞因子的影响。在CD·LAC诱导的第一阶段，OK 432这些细胞的显著增强的细胞毒性活动。对抗塑料剂的影响（CDDP，5-FU， MTX， PEP， BLM， ADR）和辐射（1.25， 2.5， 5.0， 10.0， 20.0Gy） on CD3·ALK cells ：CD 3的积极反应-ALK细胞被两种抗塑料剂和irradiation抑制了.细胞毒性活性的这些细胞要么是受抗塑料剂或irradiation影响的.这些结果索引that ALK诱导使用与RIL-2结合抗CD 3单克隆抗体可用于口腔癌患者的口服免疫疗法，并且其在与化学疗法和辐射疗法结合的治疗效应是预期的。

A Grest number of cells, which have high level of cytotoxic activity, are demanded for successful adoptive immunotherapy with Lymphokine-Activated Killer (LAK) cells. We attempted to make culture CD3-LAK cells using anti-CD3 monoclonal antibody and interleukin-2, and investigated how the proliferative response and cytotoxic activity of LAK cells (CD3・LAK) are affected by BRM (cytokines, OK432, etc.). In clinically, therapeutic effects of the combination of radiation therapy, chemotherapy and adoptive immunotherapy are expected, therefor, we investigated the effect of these therapy on CD3-LAK cells.1. Induction of CD3・LAK cells : High proliferative response and cytotoxic activity were induced from peripheral blood lymphocytes (PBL) by using anti-CD3 monoclonal antibody and IL-2.2. The effect of cytokines (rIFNgamma, rTNF alpha, rG-CSF, rIL-1 alpha, rIL-1beta) on CD3・LAKcells : Proliferative response of CD3・LAK cells increased by rTNFalpha at low concentration of rIL-2. Cytotoxic activity of these cells were not affected by any cytokines. At the first stage of CD・LAK induction, OK432 significantly enhanced cytotoxic activity of these cells.3. The effect of antineoplastic agent (CDDP, 5-FU, MTX, PEP, BLM, ADR) and irradiation (1.25, 2.5, 5.0, 10.0, 20.0Gy) on CD3・LAK cells : Proliferative response of CD3-LAK cells were suppressed by both antineoplastic agent and irradiation.Cytotoxic activiy of these cells were neither affected by antineoplastic agent nor irradiation.These results indicate that LAK induction using together anti-CD3 monoclonal antibody with rIL-2 is available for adoptive immunotherapy on oral cancer patients, and that therapeutic effects of adoptive immunotherapy in combination with chemotherapy and radiation therapy are expected.
