About
Jean-Pierre Vartanian is a researcher in the Virology department at the Institut Pasteur in Paris, France. He is actively involved in research on viral mutagenesis, host restriction factors, and the role of APOBEC3 enzymes in viral evolution and carcinogenesis, particularly in the context of hepatitis B virus and retroviruses.
His research focuses on understanding how host cellular factors such as APOBEC3 enzymes and hypoxia-induced proteins influence viral replication and genome stability. He investigates mechanisms of viral restriction, DNA editing, and the interplay between viral infection and innate immune responses, with implications for cancer development and antiviral strategies.
The recent publications highlight a strong trend in molecular virology, especially in host-virus interactions, mutagenesis, and DNA damage responses. His work frequently explores how cellular stress conditions like hypoxia modulate antiviral defenses and how APOBEC3 family proteins contribute to both antiviral activity and genomic instability.
- Genetic and molecular mechanisms of viral restriction
- Role of APOBEC3 enzymes in viral evolution and cancer
- Hepatitis B virus-host interactions
- Mutagenesis in emerging viruses (e.g., Monkeypox)
- Innate immunity and DNA damage response
He contributes to educational programs at the Institut Pasteur, including the annual Pasteur Course Emerging Viruses, Cours Pasteur Virologie fondamentale, and several MOOCs such as Viral Outbreaks and Pandemics and Viruses and Human Cancers, indicating active mentorship and knowledge dissemination roles. While specific grants or advising relationships are not detailed, his collaborations with prominent scientists like Simon Wain-Hobson and Rémi Suspène suggest strong research network involvement.
Jean-Pierre Vartanian is associated with the Institut Pasteur’s research ecosystem, contributing to projects in virology and host-pathogen interactions, particularly within teams focused on viral physiopathology, virus-cell stress, and immunity.
