It enhances thl cell growth , inhibits th2 cell growth and enhances the cytotoxic activity of cd8 + t cells and nk cells as well as stimulates b cell igg2a production 它能促进mhci类和11类分子的表达，促进thl和ctl的分化及b细胞iggza的产生，增强nk活性和ctl活性，抑制肿瘤血管的生成。
Interferon - gamma ( ifn - y ) is a product of thl , cytotoxic t lymphocytes ( ctl ) and nk cells , and is one of the major effector molecules in cell - mediated immunity Y干扰素（ intederon唱amma ， ifn个）是由th 、 ctl及nk细胞等产生的th型细胞因子，在机体抗感染、抗肿瘤中发挥重要的作用。
Objectives firstly to prepare the vaccine of human dcs and tumor cells transfectde with pcdna3 - cea , and to observe the induction of carcinoembryonic antigen ( cea ) - specific cytotoxic t - lymphocyte responses in vitro 用脂质体将cea表达质粒转染人dc ，观察其对cea表达阳性的肿瘤的特异性免疫作用。
By far , exosomes can be secreted by most of cells in culture , such as reticulocytes , platelets , b lymphocytes , cytotoxic t lymphocytes , dc , mast cells , and some tumor cells 自此，科学家们开始重视exosomes并致力于exosomes作为肿瘤疫苗的研究。这些研究大多以dc来源的或者肿瘤细胞冲击过的dc来源的exos 。
The potency of capsaicin as an immuno - actie ligand together with its cytotoxic effects and the induction of a specific immune response could make it an attractie candidate for cancer immunotherapy 辣椒素具有免疫激活配体的潜能、细胞毒作用及特异免疫反应的诱导，以上三个作用使其成为癌症免疫治疗有吸引力的候选者。
Although taxol showed good cytotoxic activity to tumor cells growing in tissue culture and in several rodent tumor systems , its interest waned for nearly a decade for two reasons 尽管紫杉醇对在组织培养中的恶性肿瘤和几种恶性肿瘤细胞系实验中显示了极强的细胞毒性，但在被发现之后的近十年来并未能引起人们的足够广泛的重视。
< wp = 8 > il - 12 is an effective adjuvant that can initiate protective immune response . it regulates specific and nonspecific immune response by activating natural killer cells and cytotoxic t lymphocytes Il - 12是启动保护性细胞免疫的有效佐剂，在调节机体非特异性和特异性免疫方面具有重要作用，其调节方式主要通过刺激nk细胞和细胞毒淋巴细胞来完成。
Purpose : the recently described posterior reversible encephalopathy syndrome ( pres ) classically consists of reversible vasogenic edema in the posterior circulation territories , although conversion to irreversible cytotoxic edema has been described 目的：近来提出的后部可逆性脑病综合征（ pres ）主要包括后循环区域可逆的血管性水肿及不可逆的细胞毒性水肿。
Autoclaves , microwave systems and chemical disinfection equipment cannot remove the toxicity or destroy the residual amount of cytotoxic drugs , pharmaceuticals and other chemicals in the syringes and on sharp instruments such as scalpels 蒸压消毒微波消毒及化学消毒设备往往不能去除或破坏留于针筒及尖锐器材如解剖刀的残馀毒素和毒害细胞的药物及其他化学剂。
