A new question is sparking interest in HIV research: Can HIV be stopped by infusing white blood cells (WBC) from people whose bodies control HIV into people whose bodies don’t?

National Institutes of Health researchers are seeking participants—HIV-positive people who have taken two different HIV combos (and stopped responding to them) and whose CD4 count is under 400 and HIV viral load above 10,000—to get WBC infusions (not transplants) from “elite controllers”—positive people whose immune systems control HIV without meds. If a first infusion seems to lower HIV viral loads or raise CD4 counts, two more may be given at three-month intervals.
