坏死性凋亡与肿瘤免疫：RIPK1–RIPK3–MLKL轴、ZBP1信号及实验判定
坏死性凋亡（necroptosis）是一类以RIPK3–MLKL轴为核心执行机制的调节性细胞死亡，其质膜破裂可伴随DAMPs、肿瘤抗原及炎症信号释放，从而将细胞死亡与肿瘤免疫微环境变化直接连接。RIPK1依赖性信号、ZBP1介导的非经典RIPK3激活以及死亡前炎症转录共同决定其免疫输出，而不同细胞类型和微环境背景又可使坏死性凋亡呈现抗肿瘤或促肿瘤的双向效应。 ...

Necroptosis and Tumor Immunity: The RIPK1–RIPK3–MLKL Axis, ZBP1 Signaling, and Experimental Determination
Necroptosis is a form of regulated cell death centered on the RIPK3–MLKL execution axis. Plasma membrane rupture can be accompanied by the release of DAMPs, tumor antigens, and inflammatory signals, thereby directly linking cell death to changes in the tumor immune microenvironment. ...
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 ...
