About

Professor of Internal Medicine at Kremlin-Bicêtre hospital. On the aims of his research is the characterization of HIV reservoirs, HIV persistence, and deciphering latency reactivation mechanisms and latency-reactivating agents (LRAs). He specializes in HIV-related clinical trials, in particular, the epidemiology and clinical characteristics of HIV-controllers (individuals infected with HIV who can spontaneously control viremia to maintain very low viral loads).

Title: A Non-Human Primate Model For HIV Remission (pVISCONTI)

The VISCONTI study proposed that post-treatment control (PTC) of HIV infection might be favored by early antiretroviral treatment (ART) initiation. However, a formal demonstration has not been established and the underlying mechanisms leading to PTC remain elusive. The pVISCONTI program aims to assess, in standardized conditions, the impact of early versus late ART initiation on… Continue reading A Non-Human Primate Model For HIV Remission (pVISCONTI)

Title: Heterogeneity of mechanisms responsible for HIV-1 gene silencing, WP1

Despite current effective and life-prolonging combination antiretroviral therapy (ART), HIV 1 can still not be cured and remission is not attainable for most persons. Indeed, the virus persists in people receiving ART and can produce active infection upon treatment interruption due notably to reactivation of viral expression from latently-infected cells, called HIV reservoirs. HIV-1 transcriptional… Continue reading Heterogeneity of mechanisms responsible for HIV-1 gene silencing, WP1
