免疫治疗作为肿瘤治疗的一种方法当前已进行了广泛的研究。因为用各种免疫治疗方法。可引出肿瘤-特异性抗肿瘤反应,所以肿瘤疫苗起着有利于宿主的作用。然而,迄今还没有一个肿瘤疫苗可以诱发足够有效的治疗反应。最近研究表明用X 照射处理的肿瘤疫苗可诱发产生抑制细胞,它们可以促进体内肿瘤的生长。这一发现表明需要发展消除这些抑制细胞的体内方法。作者用鹿角菜(Carrageenan)强化刀豆素A(ConA)结合L_(1210)小鼠白血病疫苗诱发的原发性和继 Immunotherapy as a method of cancer treatment has been extensively studied. Because with a variety of immunotherapy methods. Can elicit tumor-specific anti-tumor responses, so tumor vaccines play a host-beneficial role. However, no tumor vaccine has so far been able to induce a sufficiently effective therapeutic response. Recent studies have shown that tumor vaccines treated with X-irradiation can induce the production of inhibitory cells that can promote tumor growth in vivo. This finding suggests that there is a need to develop in vivo methods that eliminate these inhibitory cells. The authors used Carrageenan to strengthen the concanavalin induced by ConA and L 1210 mice leukemia vaccine
