Abstract
Purposeof review: In the current quest for a complete cure for HIV/AIDS, the persistence of a long-lived reservoir of cells carrying replication-competent proviruses is the major challenge. Here, we describe the main elements and characteristics of several widely used assays of HIV latent reservoir detection.
Recent findings: To date, researchers have developed several different HIV latent reservoir detection assays. Among them, the in vitro quantitative viral outgrowth assay (QVOA) has been the gold standard for assessing latent HIV-1 viral load. The intact proviral DNA assay (IPDA) based on PCR also demonstrated the predominance of defective viruses. However, these assays all have some drawbacks and may still be inadequate in detecting the presence of ultralow levels of latent virus in many patients who were initially thought to have been cured, but eventually showed viral rebound. An accurate and precise measurement of the HIV reservoir is therefore needed to evaluate curative strategies, aimed to functional cure or sterilizing cure.
期刊介绍：
This journal intends to provide clear, insightful, balanced contributions by international experts that review the most important, recently published clinical findings related to the diagnosis, treatment, management, and prevention of HIV/AIDS.
We accomplish this aim by appointing international authorities to serve as Section Editors in key subject areas, such as antiretroviral therapies, behavioral aspects of management, and metabolic complications and comorbidity. Section Editors, in turn, select topics for which leading experts contribute comprehensive review articles that emphasize new developments and recently published papers of major importance, highlighted by annotated reference lists. An international Editorial Board reviews the annual table of contents, suggests articles of special interest to their country/region, and ensures that topics are current and include emerging research. Commentaries from well-known figures in the field are also provided.
