研究目的:

本项目旨在深入理解脂肪肉瘤的发病机制,并探索可能的治疗新靶点,为开发有效的脂肪肉瘤治疗策略提供科学依据。具体通过综合分析巨噬细胞表型、mTOR信号通路与脂滴动态变化的关系,为脂肪肉瘤治疗提供新靶点和策略。  

Objectives of Study:

This project aims to deeply understand the pathogenesis of liposarcoma and explore possible new therapeutic targets, providing scientific basis for the development of effective liposarcoma treatment strategies. Specifically, by comprehensively analyzing the relationship between macrophage phenotype, mTOR signaling pathway and dynamic changes in lipid droplets, we provide new targets and strategies for liposarcoma treatment.
