科技日报北京电,据纽约州立大学布法罗分校近日报道,该校研究人员利用无害的大肠杆菌研发出一种可输送疫苗的“细菌胶囊”。用这种胶囊输送疫苗能引发特定免疫反应,比现有接种疫苗效率更高,效果更好。研究人员近日在《科学进展》杂志上撰文称,他们设计了一种能成功抵抗肺炎球菌的“细菌胶囊”。感染肺炎球菌会导致肺炎、脓毒症、耳部感染、脑膜炎等疾病。研究人员在大肠杆菌外面缠裹了一种叫做β氨基酯的人工合成聚合物,就像穿在细 Beijing Science and Technology Daily, according to the University of New York at Buffalo recently reported that the researchers use harmless E. coli developed a vaccine can be transported “bacterial capsules.” Vaccination with this capsule can elicit a specific immune response that is more efficient and effective than existing vaccinations. In a recent article in Science Progress, the researchers said they designed a “bacterial capsule” that would successfully fight pneumococci. Infection with pneumococcal pneumonia can cause pneumonia, sepsis, ear infections, meningitis and other diseases. Researchers wrapped around the outside of E. coli, a synthetic polymer called β-amino-esters, like to wear thin
