: The introduction of combination antiretroviral therapy (cART) has switched HIV-1 infection from a lethal disease to a chronic one. Indeed, cART is a lifelong treatment since its interruption is always followed by a rapid rebound of viremia from both cellular and anatomical viral reservoirs where the integrated HIV-1 provirus remains transcriptionally silent or maintains low-levels of viral replication, thereby preventing HIV-1 eradication. As therapeutic approach, the "shock and kill" strategy has emerged with the main objective to reactivate HIV-1 transcription from latency by using latency reversing agents (LRAs) prior to kill the reactivated infected cells by improving host immune responses. In this context, the development of tools such as HIV-1 latently infected cell lines have drastically increased our knowledge about HIV-1 latency and how to counteract this highly heterogeneous phenomenon. In this chapter, we will describe several chronically HIV-1 infected T-lymphocytic cell lines as useful surrogate models to study reversible HIV-1 proviral latency in CD4+ T cells in vitro before approaching more complex and expensive models.

Abstract
: The introduction of combination antiretroviral therapy (cART) has switched HIV-1 infection from a lethal disease to a chronic one. Indeed, cART is a lifelong treatment since its interruption is always followed by a rapid rebound of viremia from both cellular and anatomical viral reservoirs where the integrated HIV-1 provirus remains transcriptionally silent or maintains low-levels of viral replication, thereby preventing HIV-1 eradication. As therapeutic approach, the "shock and kill" strategy has emerged with the main objective to reactivate HIV-1 transcription from latency by using latency reversing agents (LRAs) prior to kill the reactivated infected cells by improving host immune responses. In this context, the development of tools such as HIV-1 latently infected cell lines have drastically increased our knowledge about HIV-1 latency and how to counteract this highly heterogeneous phenomenon. In this chapter, we will describe several chronically HIV-1 infected T-lymphocytic cell lines as useful surrogate models to study reversible HIV-1 proviral latency in CD4+ T cells in vitro before approaching more complex and expensive models.File | Dimensione | Formato | |
