HIV Vaccine Should Adapt as Virus Mutates

Human immunodeficiency virus is a highly variable virus that adapts to a person’s immune response during the lifetime infection, and a study published in Nature Medicine shows that viral adaptation in HIV can predict a person’s current disease status, as well as the degree to which newly transmitted HIV-1 is adapted to their new host.

By using a novel method to measure the extent of adaptation of a virus to a person’s cellular immune response, the investigators were able to predict how rapidly the disease would progress in that person.

The cellular arm of the immune response, through CD8+ T-cells, eliminates HIV-infected cells. These T-cells are activated by pieces of the virus, peptide epitopes, presented on the human leukocyte antigen proteins on the surface of antigen-presenting cells. HLA is a cell surface protein that is one of the most polymorphic variable parts of the human genome, as unique as each person’s DNA.

Some spontaneous mutations in HIV change the epitopes, the antigens to which a T-cell binds, so that the HLA proteins no longer present them effectively, and no longer stimulate an immune response. This process of viral adaptation is constantly occurring, and some adaptations persist even after sequential transmissions to new individuals.

An international team, led by scientists from UAB, Microsoft Research, and Emory University, uses a model to quantify viral adaptation, showing that being infected by a virus highly adapted to their immune response is very detrimental to that individual.

“Individuals who were infected by a pre-adapted virus progressed three times faster to low CD4 counts and had much higher viral loads,” said Jonathan Carlson, PhD, senior researcher at Microsoft Research.

The researchers show that epitopes that are adapted are poorly recognized by the immune system when they are transmitted to individuals, and even when the adapted epitope is recognized, the immune response is much less effective at killing infected cells.

In this way, parts of the virus that would normally trigger an immune response are invisible to key components of the immune system, suggesting that universal holes exist in the immune response.

“If we can’t get functional responses to those adapted epitopes in the context of natural infection, it will be challenging to get responses induced by a vaccine,” said Eric Hunter, MD of Emory University.

An analysis of immune responses measured in the Step HIV vaccine trial showed that the more adapted the vaccine candidate, the poorer the response.

“As vaccines are developed for prevention of HIV, it is important to think about how we are designing it,” said Paul Goepfert, MD, director of UAB’s Alabama Vaccine Research Clinic. “To get the immune system to respond to the vaccine, you have to think about its response to the adapted form of HIV, and focus on those parts of the virus that are most difficult to undergo adaptation.

“The ideal vaccine would produce antibodies and cell-mediated responses. We haven’t optimized vaccines to be nonadapted to see if they would improve efficacy.”

While the number of infections seen within the United States has decreased over the past 10 years, there are still more than 50,000 new infections each year. Effective therapy to treat HIV has been available for almost 20 years, but developing better prevention methods is essential in decreasing or ending the number of cases of infection.
