T细胞生长因子(TCGF)或白细胞间介素(几2)是在体外培养中可刺激活化个细胞持续增殖的一种有力的免疫调节分子;它可影响T细胞依赖的免疫应答,并在机体中显示对恢复免疫缺陷有效。鉴于各种实验动物及人类肿瘤均涉及T细胞介导和T细胞依赖的肿瘤特异性免疫防御机理,因而设想,给带瘤机体注射TCGF是否可以通过活化或扩大机体的抗肿瘤效应功能, T-cell growth factor (TCGF) or interleukin (2) is a potent immunoregulatory molecule that stimulates the sustained proliferation of activated cells in vitro; it can affect T-cell-dependent immune responses in the body. It has been shown to be effective in restoring immune defects. Given that various experimental animals and human tumors are involved in T cell-mediated and T-cell-dependent tumor-specific immune defense mechanisms, it is envisaged whether injecting tumor cells with TCGF can activate or expand the body’s anti-tumor effect.
