The key to immunity?

The article focuses on the discovery of a molecular lock called CC-CKR-5 which enables the human immunodeficiency virus (HIV) to access the lymphocytes it damages. This discovery may provide an important detail as to how the bodies of those who are immune to HIV are able to keep it out. This molecular lock is linked with a group of messenger molecules known as chemokines. Papers describing this lock have been published by researchers from the Rockefeller University in New York, the New York University and the National Institutes of Health.
