Efficient mRNA delivery to resting T cells to reverse HIV latency.

ABSTRACT: A major hurdle to curing HIV is the persistence of integrated proviruses in resting CD4⁺ T cells that remain in a transcriptionally silent, latent state. One strategy to eradicate latent HIV is to activate viral transcription, followed by elimination of infected cells through virus-mediated cytotoxicity or immune-mediated clearance. We hypothesised that mRNA-lipid nanoparticle (LNP) technology would provide an opportunity to deliver mRNA encoding proteins able to reverse HIV latency in resting CD4⁺ T cells. Here we develop an LNP formulation (LNP X) with unprecedented potency to deliver mRNA to hard-to-transfect resting CD4⁺ T cells in the absence of cellular toxicity or activation.
