Dr Sáez-Cirión received his PhD in Science in 2001 from the University of the Basque Country, Leioa, Spain. He joined the Institut Pasteur in Paris as a Postdoc in 2003 after a first postdoctoral period at the FDA-CBER in Bethesda. He leads now the Viral Reservoirs and Immune Control Unit. His research is currently focused in understanding (i) the mechanisms underlying control of HIV infection in natural HIV controllers and post-treatment controllers in remission of HIV infection after interruption of antiretroviral treatment; (ii) the factors associated with the establishment of HIV reservoirs and devising new approaches to tackle them.
HIV Science MOOC
In this MOOC we will review different aspects of HIV infection: from its biological origin and its identification as the causative agent of AIDS to the perspectives of eradication. Register on: https://www.fun-mooc.fr/en/courses/hiv-science/ Flyer: MOOC_VIH_2022 […]
Humoral immunoprofiling in HIV-1 post-treatment controllers
Rare infected individuals who initiated antiretroviral therapy (ART) very early during primary infection can enter in remission after its interruption, a phenomenon known as post-treatment control. Interestingly, early treatment has been associated with the […]
The ANRS 12225-Pediacam study is coordinated by Mr. Tejiokem at the Center Pasteur in Cameroon. Since 2007, the project has included children exposed or infected with HIV-1 and a group of unexposed and uninfected […]

ICISTEM-International Collaboration to guide and investigate the potential for HIV cure by Stem Cell Transplantation
ICISTEM is a collaborative project to guide and investigate the potential for HIV cure in HIV-infected patients requiring allogeneic stem cell transplantation for hematological disorders. The ICIISTEM consortium is composed of an expert European […]
Etude ANRS-EP59-CLEAC (Comparison of Late versus Early Antiretroviral therapy in HIV-infected Children) : Etude physiopathologique comparant l’impact de l’instauration précoce (avant 6 mois) ou tardive (après 2 ans) du traitement antirétroviral sur l’évolution immuno-virologique des enfants infectés par le VIH-1 en période périnatale)
A collaborative study with members of Pasteur Institute (A. Saez-Cirion, D. Scott-Algara), french perinatal cohort (ANRS CO10; J. Warszawsky) and 10 hospitals from Paris Area (Principal investigator, P. Frange). The study has included 76 […]
Natural Control of HIV-1 Infection
HIV-controllers (HIC) (also called “elite controllers” or “elite suppressors”) are rare (less than 1%) HIV-infected patients who control viral replication to undetectable levels in the absence of antiretroviral treatment. In the context of the […]
Role of CD8 T cells responses in the control of HIV-2 infection-ANRS Immunovir2
The number of persons living with HIV-1 is around 35 million while roughly one million persons are living with HIV-2, with a decreasing prevalence. Both HIV-1 and HIV-2 are associated with AIDS, however most HIV-2 […]
