Strategies to target non-T-cell HIV reservoirs

Purpose of review: A central question for the HIV cure field is to determine new ways to target clinically relevant, latently and actively replicating HIV-infected cells beyond resting memory CD4⁺ T cells, particularly in anatomical areas of low drug penetrability. Recent findings: HIV eradication strategies being positioned for targeting HIV for extinction in the CD4⁺ T-cell compartment may also show promise in non-CD4⁺ T-cells reservoirs. Furthermore, several exciting novel therapeutic approaches specifically focused on HIV clearance from non-CD4⁺ T-cell populations are being developed. Summary: Although reservoir validity in these non-CD4⁺ T cells continues to remain debated, this review will highlight recent advances and make an argument as to their clinical relevancy as we progress towards an HIV cure.
