The C-C chemokine receptor type 5 (CCR5) is a receptor expressed by T-cells and macrophages that serves as a co-receptor for macrophage-tropic HIV-1. Loss of CCR5 is associated with resistance to HIV-1. Here we combine the live cell-based SELEX with high throughput sequencing technology to generate CCR5 RNA aptamers capable of specifically targeting HIV-1 susceptible cells (as siRNA delivery agent) and inhibiting HIV-1 infectivity (as antiviral agent) via block of the CCR5 required for HIV-1 to enter cells. One of the best candidates, G-3, efficiently bound and was internalized into human CCR5 expressing cells. The G-3 specifically neutralized R5 virus infection in primary peripheral blood mononuclear cells, and in vivo generated human CD4+ T cells with a nanomolar IC50. G-3 was also capable of transferring functional siRNAs to CCR5 expressing cells. Collectively, the cell-specific, internalizing, CCR5-targeted aptamers and aptamer-siRNA conjugates offer promise for overcoming some of the current challenges of drug resistance in HIV-1 by providing cell-type- or tissue-specific delivery of various therapeutic moieties.
