Abstract
Enhanced human immunodeficiency virus (HIV)-specific immunity may be required for HIV eradication. Administration of autologous, ex vivo expanded, virus-specific, cytotoxic T-lymphocytes derived from HIV-infected patients on suppressive antiretroviral therapy (HXTCs) are a powerful tool for proof-of-concept studies. Broadly specific, polyclonal HXTCs resulting from ex vivo expansion demonstrated improved control of autologous reservoir virus compared to bulk CD8+ T cells in viral inhibition assays. Furthermore, patient-derived HXTCs were able to clear latently infected autologous resting CD4+ T cells following exposure to the latency-reversing agent, vorinostat. HXTCs will be ideal reagents to administer with precise control in future in vivo studies in combination with latency-reversing agents.
