A 63-year-old man known as the Oslo patient is "likely cured" of HIV after a stem-cell transplant remodeled his entire immune system.

Prior to this case, a handful of other HIV patients who received similar transplants had entered long-term remission from the infection. In those cases, the donated cells came from people unrelated to the patients, but in the Oslo patient's case, the transplanted cells came from his brother. His sibling happened to carry a genetic mutation that made him resistant to HIV, doctors reported Monday (April 13) in the journal Nature Microbiology.
