Alzheimer's disease (AD) is the most common cause of neurodegeneration. It is characterized by deposits of amyloid beta (Aβ) plaques and impaired memory. Microglia are associated with AD. They are activated in the AD brain and AD models. However, the exact role of microglia has not been established. We thus investigated the role of microglia in AD models using a primary culture and an ex-vivo assay. We showed that oligomerized Aβ is toxic to neurons in the primary culture. In the ex-vivo assay, a microglial cell line removed amyloid plaques in the brain of 5XFAD (AD model) mice. To verify if microglia can be protective for the neuron, we co-cultured neurons with primary microglia and treated them with Aβ. The loss of neurons, induced by amyloid toxicity, was attenuated by co-cultured microglia. Taken together, our data suggest that microglia promote neuronal survival by phagocytic clearance of Aβ in AD models.

There is no denying that the massive spread of COVID-19 around the world has worried everyone. The virus can cause mild to severe symptoms in various organs, especially the lungs. The virus affects oxidative stress in the cells. Reactive Oxygen Species modulator 1 (ROMO1) is one of the most important mitochondrial proteins that plays a critical regulatory role in the production of Reactive Oxygen Species (ROS). According to the studies, COVID-19 can promote oxidative stress through some important pathways, for instance, TNF-α and NF-κB routes. Furthermore, ROMO1 is closely related to these pathways and its dysfunction may affect these routes, then promote oxidative stress, and ultimately cause tissue damage, especially in the lungs. Another factor to consider is that the TNF-α and NF-κB pathways are associated with ROMO1, COVID-19, and oxidative stress. To summarize, it is hypothesized that COVID-19 may increase oxidative stress by affecting ROMO1. Understanding the exact molecular mechanisms of ROMO1 in the pathogenesis of COVID-19 can pave the way to find better therapeutic strategies.
不可否认，新冠肺炎疫情在全球范围内的大规模传播让每个人都感到担忧。这种病毒可以在各个器官，特别是肺部，引起轻微到严重的症状。病毒影响细胞的氧化应激。活性氧调节因子1 (Reactive Oxygen Species modulator 1, ROMO1)是线粒体中最重要的蛋白之一，在活性氧(Reactive Oxygen Species, ROS)的产生中起关键的调节作用。研究表明，COVID-19可通过TNF-α、NF-κB等重要途径促进氧化应激。此外，ROMO1与这些通路密切相关，其功能障碍可能影响这些通路，进而促进氧化应激，最终导致组织损伤，尤其是肺组织损伤。另一个需要考虑的因素是TNF-α和NF-κB通路与ROMO1、COVID-19和氧化应激相关。综上所述，我们假设COVID-19可能通过影响ROMO1来增加氧化应激。了解ROMO1在COVID-19发病机制中的确切分子机制可以为寻找更好的治疗策略铺平道路。

COVID-19 vaccine hesitancy will likely increase in the unvaccinated general population because of several vaccine safety issues that arose during priority vaccination. To investigate the potential rate of COVID-19 vaccine hesitancy in the unvaccinated population and evaluate factors that affect the attitude towards vaccine acceptance, a cross-sectional survey was performed. A telephone survey was conducted in 1,357 people older than 18 years; 99 were excluded from the analysis because they had already been vaccinated (n=58) or hesitated (n=41) after an official call. The COVID-19 vaccine hesitancy rate was 21.9% and was highest among those aged under 30 years (33.4%) and lowest among those aged 65 years and over (8.7%). Age, occupation, and perceived confidence in vaccine safety and efficacy were associated with vaccine hesitancy. These findings suggest that public health authorities should strengthen the spread of correct information, especially in the younger population, to increase vaccination rates.
