“Boston researchers are reporting the return of [HIV] in two patients who had become virus-free after undergoing bone marrow transplants, dashing hopes of a possible cure that had generated widespread excitement,” the Boston Globe reports. “The rebound of the virus shows its persistence, and that it can hide in places in the body where it’s hard to find, said the lead scientist, Dr. Timothy Henrich of Brigham and Women’s Hospital,” who presented the findings at an international AIDS research conference in Florida, the newspaper adds. “Other researchers who heard the presentation said the results were disappointing but the Boston team’s approach and data will dramatically advance strategies for battling HIV,” the Boston Globe writes (Lazar, 12/6).
