Institut Cochin – ASSISTANT-ENGINEER FELLOWSHIP
ASSISTANT-ENGINEER FELLOWSHIP FOR 3 YEARS
Our laboratory “Retrovirus, Infection and Latency” studies the molecular battle between proteins
encoded by HIV-1 and HIV-2, the causative agents of AIDS, and host defence factors.
Profile: We are looking for a highly motivated candidate, who has a very good background in molecular and cellular biology and in biochemistry. Prior experience in laboratory is required.
Job information: Funding is available for 3 years starting from December 2022 (grant from FRM-
Fondation pour la Recherche Médicale). Salary will be adjusted depending on experience. The
laboratory is hosted within the “Institut Cochin” in Paris. This institute provides an exciting multidisciplinary environment with state-of-the-art and efficient core facilities.
Project: HIV-1 and HIV-2 eradication faces a major obstacle that is viral persistence in reservoir cells despite antiretroviral treatment. HIV latency refers to silent viruses, which remain competent, and, in
case the treatment is interrupted, can still produce infectious particles. Latency can be explained by
an inhibition of viral transcription or by a defect in the post-transcriptional steps. We have shown that
the HUSH epigenetic complex represses the HIV-1 LTR promoter and proposed that HUSH could be a
player in HIV latency. Furthermore, we and others found that specific lentiviral proteins from HIV or
SIV (Simian virus) antagonize HUSH to increase viral expression, highlighting the molecular battle
between the virus and its host.
The future assistant-engineer will help the different projects of the lab and, more specifically, will be
in charge of the development of a molecule that targets HUSH and modulates its activity, based on the
study of viral antagonists.
Application: Candidates should send their applications, as well as names and letters of potential
referees to the following e-mail address: email@example.com
