Neural cell death is a critical pathological mechanism underlying the development and progression of central nervous system (CNS) diseases, where programmed cell death (PCD) pathways serve as critical regulatory hubs. In addition to classical apoptosis and autophagy, emerging PCD modalities including necroptosis, pyroptosis, ferroptosis, and cuproptosis exhibit distinct activation patterns in different neurological diseases. Long non-coding RNAs (lncRNAs) have emerged as pivotal regulators of these PCD processes through multiple molecular strategies by modulating chromatin accessibility, assembling signaling complexes, and regulating post-transcriptional processes. These regulatory interactions vary by cellular location and disease stage, influencing cell fate through membrane receptors, kinase cascades, and nuclear transcriptional programs. In various CNS pathologies, specific lncRNAs display dual regulatory capacities-promoting neuronal death by amplifying cytotoxic signals or conferring neuroprotection by inhibiting these pathways. The dynamic lncRNA-PCD interactions offer therapeutic potential through targeted modulation of lncRNA networks to control neuronal survival. Future investigations should prioritize systematic mapping of context-specific lncRNA regulatory networks governing distinct PCD modalities, concurrently advancing spatial epigenomic editing technologies for precise manipulation of these regulatory circuits. Understanding these molecular interactions better will help identify therapeutic targets and guide CNS drug development.
神经细胞死亡是中枢神经系统(CNS)疾病发生和发展的关键病理机制,其中程序性细胞死亡(PCD)途径起着关键的调控枢纽作用。除了经典的凋亡和自噬外,包括坏死性凋亡、炎性小体介导的细胞焦亡、铁死亡和铜死亡在内的新兴PCD模式在不同的神经疾病中表现出不同的激活模式。长链非编码RNA(lncRNAs)已成为这些PCD过程的关键调节因子,通过多种分子策略调节染色质可及性、组装信号复合物和调控转录后过程。这些调节相互作用因细胞位置和疾病阶段而异,通过膜受体、激酶级联反应和核转录程序影响细胞命运。在各种中枢神经系统疾病中,特定的lncRNAs表现出双重调节能力,即通过放大细胞毒性信号促进神经元死亡,或通过抑制这些途径赋予神经保护作用。动态的lncRNA-PCD相互作用通过靶向调节lncRNA网络来控制神经元存活,从而提供了治疗潜力。未来的研究应优先系统地绘制调控不同PCD模式的特定背景lncRNA调控网络,同时推进空间表观基因组编辑技术,以精确操纵这些调控回路。更好地理解这些分子相互作用将有助于确定治疗靶点并指导中枢神经系统药物开发。
