哈佛医学院副教授Dr. Marcus Altfeld 和麻省综合医院的同行们对100名新近感染爱滋病毒的患者进行了血样分析。结果表明在感染HIV爱滋病毒的早期，人体如何进行免疫反应基本上取决于免疫系统中一些特有、遗传而来的物质。这个发现可能为爱滋疫苗的研制提供了重要的基础。

Early-stage Immune Response to HIV May Depend on Inherited Factors
How well an individual's immune system controls HIV during the earliest phases of infection appears partly to depend on the specific versions of key immune-system molecules that have been inherited. Harvard Medical School associate professor Dr. Marcus Altfeld and colleagues at Massachusetts General Hospital analyzed blood samples from more than 100 people recently infected with HIV. Their findings may provide important clues for vaccine development.
