艾滋病毒相关的神经认知障碍(HAND)仍然是一个未解决的问题,尽管使用抗逆转录病毒治疗仍然存在。我们已经获得的数据表明,HIV-gp 120蛋白通过代谢重编程促进神经变性。这导致ATP水平降低,线粒体DNA拷贝数减少,线粒体嵴丢失,这对线粒体生物发生都很重要。gp 120蛋白还破坏线粒体运动和突触可塑性。搜索所涉及的机制,我们发现,gp 120改变了环磷酸腺苷反应元件结合蛋白(CREB)磷酸化丝氨酸残基133必要的功能作为一个转录因子。由于CREB调节PGC 1 α和BDNF基因的启动子,我们发现CREB去磷酸化导致PGC 1 α和BDNF功能丧失。数据在体外和体内进行了验证。在磷酸二酯酶蛋白4(PDE 4)抑制剂咯利普兰的存在下,gp 120的负面影响在细胞和动物中得到缓解,恢复CREB磷酸化。我们的结论是,HIV-gp 120蛋白通过抑制CREB蛋白的功能,有助于HAND。
HIV-associated neurocognitive disorders (HAND) remain an unsolved problem that persists despite using antiretroviral therapy. We have obtained data showing that HIV-gp120 protein contributes to neurodegeneration through metabolic reprogramming. This led to decreased ATP levels, lower mitochondrial DNA copy numbers, and loss of mitochondria cristae, all-important for mitochondrial biogenesis. gp120 protein also disrupted mitochondrial movement and synaptic plasticity. Searching for the mechanisms involved, we found that gp120 alters the cyclic AMP response element-binding protein (CREB) phosphorylation on serine residue 133 necessary for its function as a transcription factor. Since CREB regulates the promoters of PGC1α and BDNF genes, we found that CREB dephosphorylation causes PGC1α and BDNF loss of functions. The data was validated in vitro and in vivo. The negative effect of gp120 was alleviated in cells and animals in the presence of rolipram, an inhibitor of phosphodiesterase protein 4 (PDE4), restoring CREB phosphorylation. We concluded that HIV-gp120 protein contributes to HAND via inhibition of CREB protein function.
