Gene Found In Black Death Survivors Stops HIV

According to research done by Dr Stephen O’Brien, a mutated gene known as delta 32 found in Black Death survivor descendants, stops HIV in its tracks. In order to be immune both parents have to have the delta 32 gene. In 1996, research showed that delta 32 prevents HIV from entering human cells and infecting the body. O’Brien thought this principle could be applied to the plague bacteria, which affects the body in a similar manner. To determine whether the Eyam plague survivors may have carried delta 32, O’Brien tested the DNA of their modern-day descendents
