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 a research team in the HIV Inflammation and Persistence 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.
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 […]

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 […]
