以色列研究人员现已研制出一种抗葡萄球菌和链球菌强毒株的强有力武器,并在小鼠试验中检验有效。葡萄球菌和链球菌能引致中毒性休克综合征。分子病毒学教授Raymond Kaempfer领导的研究小组在近期的《自然医学》杂志上介绍了其研究突破。 Kaempfer和Gila Arad等人花费4年时间设计并开发了这种可阻断超级抗原活性的合成肽拮抗剂,超级抗原是由大量细菌分泌的致命性毒素。研究人员使小鼠暴露 Israeli researchers have now developed a powerful weapon against virulent strains of Staphylococcus aureus and Streptococcus and tested them in mice. Staphylococci and streptococci can cause toxic shock syndrome. A team led by Raymond Kaempfer, a professor of molecular virology, presented his research breakthrough in a recent issue of Nature Medicine. Kaempfer and Gila Arad spent four years designing and developing this synthetic peptide antagonist, which blocks the activity of superantigens, the deadly toxin secreted by a large number of bacteria. Researchers exposed mice
