Professor of virology at Paris-Descartes University and member of the Academy of Medicine. She specializes in HIV pathophysiology, the cellular and molecular characterization of HIV reservoirs, the markers of HIV persistence, the mechanisms underlying durable HIV control among post-treatment controllers, and the assessment of therapeutic strategies/ techniques for HIV cure and eradication.

Title: Viral dynamics of rebound and control following early treatment of HIV/SIV (NIH)

The results of the ANRS EP47 VISCONTI (Viro-Immunological Sustained COntrol after Treatment Interruption) study provided proof of concept that a state of sustainable HIV remission may be induced in at least some people with HIV: the post-treatment controllers (PTC). Unlike natural controllers, PTCs presented a symptomatic primary HIV-1 infection with high viral load and low… Continue reading Viral dynamics of rebound and control following early treatment of HIV/SIV (NIH)

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)
