ResearchOur laboratory studies signaling pathways regulating innate immunity and cell death. The research focus is to elucidate the molecular mechanisms and roles of cytosolic pattern recognition receptors of the Nod-like receptor (NLR) family in host defense, chronic inflammation and cancer.
Several established approaches, ranging from genetically modified mouse models to biochemistry and cellular immunology methods, are used in our laboratory to gain insight into the mechanisms that govern host-pathogen interactions, tumor biology and inflammatory-mediated immune disorders.
We are particularly investigating the functions of various apoptosis effectors in infection, inflammatory bowel diseases and colorectal cancer.
Postdoctoral and graduate projects are regularly available.

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.
Dr. Yeretssian did not report having any of the following types of financial relationships with industry during 2013 and/or 2014: consulting, scientific advisory board, industry-sponsored lectures, service on Board of Directors, participation on industry-sponsored committees, equity ownership valued at greater than 5% of a publicly traded company or any value in a privately held company. Please note that this information may differ from information posted on corporate sites due to timing or classification differences.
Mount Sinai's faculty policies relating to faculty collaboration with industry are posted on our website at http://icahn.mssm.edu/about-us/services-and-resources/faculty-resources/handbooks-and-policies/faculty-handbook. Patients may wish to ask their physician about the activities they perform for companies.
