中国研究人员开发出针对SFTS的超级抗体

中国研究人员开发出一种强效抗体,可能对抗严重热性血小板减少综合征(SFTS),这是一种由蜱虫传播的致命疾病,死亡率高达30%。这一突破为应对东亚地区日益严重的蜱媒威胁提供了希望。

在蜱媒疾病领域,莱姆病常常占据头条。例如,埃隆·马斯克人工智能初创公司xAI的12位创始成员之一格雷格·杨在1月底表示,他因诊断出莱姆病而从公司退后,称意外吃错食物会让他“极度疲惫”,需要几天才能恢复。

然而,还有一种更危险的蜱媒疾病,中国一所大学的研究团队可能已找到治疗方法。这种疾病是严重热性血小板减少综合征(SFTS),由Dabie bandavirus引起,通过Haemaphysalis longicornis蜱虫传播。该综合征于2009年首次被识别,当时调查涉及突发高热的未知疾病病例。

研究人员表示,这一发现“开辟了应对蜱虫日益增长威胁的新途径”。SFTS的死亡率高达30%,主要影响东亚地区,包括中国、日本和韩国。该抗体被描述为“超级抗体”,可能为预防和治疗这种寄生威胁提供新方式。

这一进展突显了蜱媒疾病的全球关注度增加,从欧洲、北美到澳大利亚和新西兰,类似威胁正在扩展。研究团队位于杭州,强调了本地创新在公共卫生挑战中的作用。

Australian researchers report they have engineered monoclonal antibodies that recognize pseudaminic acid—a sugar made by bacteria but not by humans—and used them to help eliminate multidrug-resistant Acinetobacter baumannii infections in mice, a step toward potential passive-immunotherapy treatments for hard-to-treat hospital infections.

Researchers from Australia have reported positive results from a Phase II clinical trial of a new carbohydrate-based drug for treating sepsis. The trial, involving 180 patients in China, demonstrated the drug's ability to reduce the condition's severity. This development offers hope for the first targeted therapy against a leading cause of global deaths.

Scientists have harvested antibodies from the blood of paediatricians to develop new preventative treatments for respiratory syncytial virus (RSV) and human metapneumovirus. These antibodies outperform existing therapies by up to 25 times and target a wider range of strains. The discovery stems from the natural immunity built by paediatricians through years of exposure to respiratory viruses.

Scientists have created innovative nanoparticles designed to destroy harmful proteins linked to dementia and cancer. These particles can access difficult tissues like the brain and precisely eliminate problematic proteins without broad side effects. The technology shows early promise for precision medicine.

Scientists at Northwestern Medicine have developed an antibody that counters pancreatic cancer's sugar-based disguise, enabling the immune system to attack tumors more effectively. In mouse studies, the therapy slowed tumor growth by restoring immune activity. The team is preparing the antibody for human trials.

Researchers at Oregon Health & Science University have pinpointed specific sites on NMDA receptors targeted by harmful antibodies in a rare autoimmune brain disorder known as "Brain on Fire." This discovery, published in Science Advances, could lead to more precise treatments and earlier detection. The condition affects about 1 in 1 million people annually, mainly young adults, causing severe symptoms like seizures and memory loss.

Researchers at Stanford Medicine have created an experimental nasal spray vaccine that protects mice against multiple respiratory threats, including COVID-19, flu, bacterial pneumonia, and allergens. The vaccine activates the lungs' innate immune system for months, offering broad defense without targeting specific pathogens. Published in Science on February 19, the study suggests potential for human trials soon.
