Abstract

Allogeneic stem cell transplantation (alloSCT) of homozygous CCR5 Δ32 stem cells once resulted in the cure of human immunodeficiency virus (HIV) infection. We have recently reported a viral breakthrough in a similar setting. Here, we demonstrate that the rapid rebound after alloSCT was related to a highly replicative CXCR4-tropic HIV variant, which could already be detected before alloSCT.
