Purpose Of Review:
To summarize the heterogeneity in the elite controllers population with the aim to identify a compatible profile with a persistent HIV remission, making distinction between persistent elite controllers, people with HIV (PWHIV) who permanently maintain virological control in the absence of antiretroviral treatment (ART), and transient elite controllers, PWHIV who eventually lose virological control. For this purpose, it is important to consider the mechanisms and biomarkers that have previously been associated with the maintenance and loss of the natural virological control.
Recent Findings:
Transient elite controllers, before losing virological control, exhibit a distinct metabolomic, proteomic, microRNAs (miRNA), immunological and virological profile compared to persistent elite controllers. In addition to a reduced and less polyfunctional HIV-specific T-cell response, transient elite controllers show a greater proportion of intact proviruses integrated into genic regions. In contrast, persistent elite controllers display a privileged HIV-1 reservoir profile with absence of detected intact proviruses or low proportion of clonal intact proviruses preferentially integrated into genomic features associated with HIV-1 transcriptional repression.
Summary:
According to previous studies, the comprehensive characterization of persistent elite controllers might be crucial to identify other PWHIV with this distinct profile as spontaneously cured.
