近期主要工作和进展
揭示了肿瘤发生发展的新机制:我们的研究发现,组织的纤维化为肿瘤细胞的生成和发展提供了有利的微环境,纤维化可促进正常细胞向肿瘤细胞转化及增值;纤维化为肿瘤细胞提供了适宜其定居和生长的微环境并促进肿瘤转移灶的形成。TGF-alpha / Smad3信号通路在这一过程中起到关键作用可以作为药物筛选的新靶点。发现了柚皮素和柚皮苷可以特异性干预TGF-alpha / Smad3信号通路起到预防和治疗纤维化及癌症作用。
提出了肿瘤化疗的新观点和新思路:大多数化疗药物的作用靶点在细胞内,如阿霉素和顺铂等作用于细胞核的DNA,紫杉醇和长春新碱等作用胞浆的微管;或已具有耐药性的肿瘤细胞,通过外排机制将药物泵出细胞外,细胞内的药物浓度不足以抑制细胞的增殖。仅仅将药物输送到肿瘤组织(组织靶向)是不够的,在提高肿瘤组织选择性基础上,如何提高药物的组织渗透性及对肿瘤细胞选择性并能跨膜输送至细胞内达到有效浓度已成为肿瘤治疗的新的挑战。我们提出了利用纳米药物输送系统既实现肿瘤组织的靶向渗透性又实现肿瘤细胞内的靶向富集,为临床治疗肿瘤提供新的有效手段和策略。
提出了肿瘤免疫治疗的新方案:治疗性肿瘤疫苗通过使用肿瘤抗原刺激患者自身的免疫系统,使之产生杀伤肿瘤细胞的免疫反应,对抗甚至清除手术及放化疗后体内残存的肿瘤病灶和转移肿瘤。与传统治疗方法相比,肿瘤的免疫治疗具有特异性、长效性、低毒副作用等特点。大量的研究结果显示,纳米载体可通过多种机制的协同作用增强肿瘤抗原所诱发的免疫反应,纳米技术的发展为肿瘤治疗性疫苗的设计提供了全新的策略和方案。
