Innate immunity to dengue virus and influenza virus
The Fernandez-Sesma laboratory studies innate immunity evasion by viruses of human health interest, such a dengue virus (DENV), influenza virus and other viruses, such as HIV. The main area of research in the Fernandez-Sesma laboratory is DENV, which is the most important mosquito transmitted virus in the world for which no vaccines or antiviral drugs are currently available. Additionally the Fernandez-Sesma laboratory investigates the interactions of influenza viruses with human immune cells and the strategies of innate immune evasion developed by important human pathogen.

Summary of Research Studies:
The main focuses of study in the Fernandez-Sesma laboratory are the interactions of important human pathogens with primary human immune cells.
- Dengue virus (DENV)is an important human pathogen for which there is no vaccine or treatment available. Dengue is a flavivirus transmitted to humans by the bite of the mosquito aedes aegipti. We are studying the role of different primary human cells, such as dendritic cells (DCs) and macrophages in the initiation or evasion of immunity by DENV. We have analyzed the pattern of gene expression and cytokine secretion in different primary cells after DENV infection and have recently shown that the DENV protease complex (NS2B/3) is crucial for the inhibition of type I IFN production by DENV in primary human DCs, an important step in the generation of the innate and adaptive immune responses by this virus. We are currently studying how primary isolates of DENV are able to initiate or evade immune responses in human primary cells.
- We are also studying adaptation of DENV to human and mosquito cells as part of a DARPA funded multi-investigator project led by Dr. Raul Andino at UCSF. Our laboratory is interested in innate immune evasion by this virus as a measure of adaptation and fitness.
Physicians and scientists on the faculty of the Icahn School of Medicine at Mount Sinai often interact with pharmaceutical, device and biotechnology companies to improve patient care, develop new therapies and achieve scientific breakthroughs. In order to promote an ethical and transparent environment for conducting research, providing clinical care and teaching, Mount Sinai requires that salaried faculty inform the School of their relationships with such companies.
