New research provides further clues about long-term non-progressors

Denialists frequently cite the well-known phenomenon of some individuals with HIV living healthily for long periods without treatment as evidence that HIV does not cause AIDS. However, the existence of these rare individuals do not in fact disprove the science on HIV/AIDS. We debunked that myth here. Also, despite denialist claims to the contrary, research on how these individuals' immune systems control HIV for longer than usual has in fact been a priority and several studies have shed light on the mechanisms involved. A new study has now found slight differences in five amino acids in the HLA-B protein between long-term non-progressors and people who do not control HIV for longer than normal.
