- 生物化学 生物化学
背景情况:
- 阿尔茨海默病 (AD) 涉及异常的粉样蛋白前体蛋白 (APP) 处理和大脑低代谢,导致神经元功能障碍和Aβ积累.
- 乳酸盐是无氧糖解的产物,支持神经元功能和修复.
- 状家族成员4 (VGLL4) 调节缺氧感应通路,但其在阿尔茨海默病中的作用尚不清楚.
研究的目的:
- 调查VGLL4在阿尔茨海默氏症病原发生中的作用.
- 探索VGLL4影响APP处理和神经元损伤的分子机制.
主要方法:
- 在AD模型小鼠和细胞中评估VGLL4蛋白表达.
- 过度表达VGLL4,观察对APP处理和突触损伤的影响.
- 研究了VGLL4在缺氧下对乳酸脱酶A (LDHA) 的调节.
- 使用LDHA抑制剂酸盐来评估VGLL4的神经保护功能.
主要成果:
- 在AD模型中,VGLL4蛋白表达显著下降.
- 过度表达VGLL4减少了粉原蛋白APP处理,改善了突触损伤.

Lysosomal Hydrolases
3.8K
Lysosomes are the site for the degradation of macromolecules and biological polymers released during membrane trafficking events such as secretory, endocytic, autophagic, and phagocytic pathways. The membrane-enclosed area of the lysosome, called the lumen, contains hydrolytic enzymes active in an acidic environment. These acid hydrolases are functional at a pH between 4.5 and 5 and are involved in cellular processes such as cell signaling, energy metabolism, restoration of the plasma membrane,...

Long-term Depression
2.5K
Long-term depression, or LTD, is one of the ways by which synaptic plasticity—changes in the strength of chemical synapses—can occur in the brain. LTD is the process of synaptic weakening that occurs over time between pre and postsynaptic neuronal connections. The synaptic weakening of LTD works in opposition to synaptic strengthening by long-term potentiation (LTP) and together are the main mechanisms that underlie learning and memory.
