Days after HSCT www.aids2012.org
Washington D.C., USA, 22-27 July 2012
• Allogeneic HSCT with suppressive ART led to a sustained reduction in the HIV-1 reservoir in
PBMCs
• What is now required to fully assess the extent of HIV-1 reservoir reduction?

Zeng et al., PLoS Pathog. 2012 www.aids2012.org
Washington D.C., USA, 22-27 July 2012
Lymph node fibrosis is similar in HIVindividuals in Uganda and in chronic HIV+ individuals in the US
may account for lower baseline CD4+ T cells and less immune reconstitution with ART
may modify the size of the reservoir
may have implications for eradication and cure in the developing world www.aids2012.org
