almost three years after he received bone marrow stem cells from a donor with a rare genetic mutation that resists hiv infection – and more than 18 months after he came off antiretroviral drugs – highly sensitive tests still show no trace of the man’s previous hiv infection.

further research is underway to develop a drug that can inhibit hiv protein. chinese researchers say further work is necessary before clinical trial possible.
