Abstract :

Nuclear pore complexes (NPCs) play an important role in 3D chromatin organization as well as in regulating the expression of cellular genes and, probably, of viral genes. Moreover, recent studies, included ours, have shown the involvement of some Nups, in HIV-1 infection (1-6). Recently we showed that the passage of the HIV-1 virus through the NPCs and its integration into the host cell's genome are linked (7). Thus, Nups can have a key role in HIV-1 integration in active chromatin.
In our ongoing projects, the team aims to explore the link between NPC and HIV-1 integration sites that can influence viral transcription. We are also currently exploring the morphology of the viral pre-integration complex during the nuclear entry. Live imaging experiments in the lab can elucidate unknown dynamics of the early steps of HIV-1 infection.
