受体酪氨酸激酶异常信号在肿瘤发生、精准分型与靶向治疗中的作用
受体酪氨酸激酶（receptor tyrosine kinase，RTK）通过酪氨酸磷酸化调控细胞增殖、存活、迁移和分化。RTK突变、扩增、融合或异常表达可持续激活MAPK、PI3K/AKT、STAT和PLC等信号通路，推动肿瘤发生并影响分子分型、靶向治疗及耐药。

Role of Aberrant Receptor Tyrosine Kinase Signaling in Tumorigenesis, Precision Classification, and Targeted Therapy
Receptor tyrosine kinases (RTKs) regulate cell proliferation, survival, migration, and differentiation through tyrosine phosphorylation. RTK mutations, amplifications, fusions, or abnormal expression can continuously activate MAPK, PI3K/AKT, STAT, PLC, and other signaling pathways, thereby ...
HMGB1介导的损伤相关炎症信号与肿瘤免疫调控
HMGB1将细胞损伤转化为炎症和趋化信号，并通过TLRs、RAGE及CXCR4调控肿瘤免疫、肿瘤干性和治疗耐受。
Macrophage CCR5 Pathway: Chemotactic Signaling, Inflammatory Regulation, and Roles in Disease Microenvironments
CCR5 is one of the important chemokine receptors in macrophages. It primarily recognizes CC chemokines such as CCL3, CCL4, and CCL5, and regulates macrophage recruitment, migration, inflammatory cytokine release, phagocytic function, and tissue microenvironment remodeling through G ...
巨噬细胞CCR5通路的趋化信号、炎症调控与疾病微环境作用
CCR5是巨噬细胞中重要的趋化因子受体之一，主要识别CCL3、CCL4、CCL5等CC类趋化因子，并通过G蛋白偶联受体信号调控巨噬细胞募集、迁移、炎症因子释放、吞噬功能和组织微环境重塑。
TNF信号通路的受体分层结构、复合体转换机制与炎症—死亡效应网络
TNF信号通路是炎症反应、细胞命运调控和组织稳态维持中最核心的信号网络之一。其复杂性并不体现于TNF能够诱导炎症这一单一事实，而在于同一配体刺激可在不同受体背景、泛素化状态、细胞代谢条件和死亡检查点约束下，分别导向炎症放大、存活维持、凋亡或坏死性凋亡。 ...
TNF Signaling Pathway: Receptor Layering Structure, Complex Conversion Mechanisms, and the Inflammation–Death Effector Network
The TNF signaling pathway is one of the most central signaling networks in inflammatory responses, cell fate regulation, and tissue homeostasis maintenance. Its complexity is not reflected in the single fact that TNF can induce inflammation, but in that the same ligand stimulus can, under ...
