What Researchers Have Learned About Whether it ’s Possible to ‘Cure’ HIV

It’s the news that the HIV community has been waiting four long decades for: the hint that maybe, just maybe, HIV can be cured. Dr. Xu Yu, a principal investigator at the Ragon Institute of Massachusetts General Hospital, MIT and Harvard, as well as an associate professor of medicine at Harvard Medical School, had to check and recheck her results to be sure. In one of her patients, test after test to detect evidence of HIV in the woman’s blood came up empty. In addition to her lab’s results, “We had complementary assays in labs in Australia, D.C. and Argentina, where the patient is from, all trying to see if they find any evidence of active virus at all, and there was absolutely nothing,” says Yu. [time-brightcove not-tgx=”true”] All told, the international team analyzed more than 1.5 billion cells from the patient, who’s from Esperanza, Argentina, and none of the labs found intact traces of HIV’s whole genome in her samples. The woman tested positive for HIV after becoming infected from her partner, but soon after, her body’s immune system was somehow able to control the virus and prevent it from spilling more copies of itself into her body and, more importantly, block it from establishing reservoirs of latent virus in places like the lymph nodes—all without being on the powerful anti-HIV drugs that are normally needed to suppress the virus. This is what sets the Esperanza patient apart. Unlike the handful of ...
