淋巴因子激活的杀伤性T细胞(LAK)在体外对结肠癌细胞有作用。但在体内结肠癌细胞能抵抗LAK。由于LAK在体内不能定位肿瘤,美国麻省医院的研究人员将LAK与特异性抗体结合以增强体内作用。
Lymphokine activated killer T cells (LAK) have an effect on colon cancer cells in vitro. However, in vivo colon cancer cells are resistant to LAK. Since LAK cannot localize tumors in vivo, researchers at Massachusetts hospitals in the United States have combined LAK with specific antibodies to enhance their effects in vivo.
