半乳糖凝集素-3 (Galectin-3) 在脑肿瘤发展过程的关键抑制作用


塞维利亚大学生物化学和分子生物学系的研究小组由於发现了半乳糖凝集素-3 (Galectin-3) 蛋白在各类型脑肿瘤治療的关键作用迈出重要的一步。在这些肿瘤裡,大量的免疫系统细胞、小胶质细胞和巨噬细胞都显示半乳糖凝集素-3 (Galectin-3) 高度活跃,从而创造抑制对抗其他癌细胞的免疫細胞环境。

体外研究结果表明,半乳糖凝集素-3 (Galectin-3)在小胶质细胞的特殊抑制功能可促进促炎标记物释出,以及逆转关键免疫抑制生物标记物(乳腺癌和胶质母细胞瘤属于两种最常见和最具侵略性的脑肿瘤类型)在脑转移的体内模型研究已经验证了这些结果。在消除半乳糖凝集素-3 (Galectin-3)的基因改造模型里,小胶质细胞和巨噬细胞都呈现更具炎症和抗肿瘤状态,促使原发肿瘤和脑转移瘤大小减少多达 5 倍。

这些结果虽然還在临床前阶段,却呈現明显转化潜力。通过与隆德大学(Lund University)的合作项目,这个研究小组得以使用TD006抗体進行科研,發現這是半乳糖凝集素-3 (Galectin-3)的选择性抑制剂所导致,目前正在针对阿尔茨海默氏症患者所进行的临床试验进行评估中。 目前该团队正在致力提高半乳糖凝集素-3 (Galectin-3)抑制效果以提升对脑肿瘤的治療效果,同時也研究与其他常规疗法,如與放疗和化疗联合使用的可能性。

Testimonios

We have used AlphaGalileo since its foundation but frankly we need it more than ever now to ensure our research news is heard across Europe, Asia and North America. As one of the UK’s leading research universities we want to continue to work with other outstanding researchers in Europe. AlphaGalileo helps us to continue to bring our research story to them and the rest of the world.
Peter Dunn, Director of Press and Media Relations at the University of Warwick
AlphaGalileo has helped us more than double our reach at SciDev.Net. The service has enabled our journalists around the world to reach the mainstream media with articles about the impact of science on people in low- and middle-income countries, leading to big increases in the number of SciDev.Net articles that have been republished.
Ben Deighton, SciDevNet
AlphaGalileo is a great source of global research news. I use it regularly.
