研究发现皮肤蛋白阻断流感病毒的进入. Study finds dermcidin protein blocks flu virus entry.

一项新的研究表明, 汗水和唾液中存在一种叫做皮肤蛋白的蛋白质有助于解释为什么有些人从来没有得过流感. A new study suggests a protein called dermcidin, found in sweat and saliva, helps explain why some people never get the flu. 研究人员发现这种天然通过与关键蛋白质结合, 阻止病毒进入细胞就会阻断该病毒. Researchers found this natural peptide blocks the virus by binding to a key protein, preventing it from entering cells. 无症状个体的皮肤素水平大约是6倍,这表明它可能对流感菌株和其他呼吸道病毒提供广泛保护. Asymptomatic individuals had about six times higher levels of dermcidin, suggesting it may offer broad protection against flu strains and other respiratory viruses.
