Dr. Brian Brown is broadly trained in molecular and cellular biology with a strong focus on immunology and translational medicine. His training began with his doctoral studies in Canada and his work to establish ways to overcome the immune response hindering gene therapy. He subsequently did his postdoctoral studies in Italy where he helped develop a new platform for controlling gene expression, which has led to improvements in experimental treatments for genetic disease, cancer, and viral infection. Dr. Brown's lab is now working to identify the factors that control immunity and tolerance, and translate these findings in to strategies that can be used to turn the immune system against cancer. In 2008 Dr. Brown joined the faculty of Mount Sinai as an Assistant Professor and he was promoted to full Professor with tenure in 2018. In 2016 he becamse the Associate Director of Mount Sinai's Immunology Institute. Dr. Brown works with the Department of Genetics and Genomic Sciences and the Icahn Institute for Data Science and Genomic Technology.

Summary of Research Studies:
A major focus of our work is aimed at identifying factors that control immunity and tolerance, and utilizing this information for developing therapeutic strategies that can direct antigen-specific immune responses. We helped to identify some of the transcriptional programs that regulate dendritic cell differentiation and function (Miller et al. Nat Immunol 2012), and we discovered a pathway controlling the innate response to nucleic acids, which involves the microRNA miR-126, and the main VEGF receptor, VEGFR2 (Agudo et al. Nat Immunol 2014). We are now using a new technology we developed, called the Jedi, to probe the interactions between T cells and tissues at a granular level, and learning how the tissue controls immune responses (Agudo et al. Nat Biotech 2015). This work has important implications for the development of autoimmunity as well as cancer immunology.
Our lab also has a strong emphasis in the generation of new technologies for experimental and therapeutic applications. We led the development of a novel gene targeting technology, which is now widely used for enhancing vector and virus-based drugs in applications ranging from the treatment of genetic diseases to cancer therapy to viral vaccines (Brown et al. Nat Med 2006, Brown et al. Nat Biotech 2007, Brown and Naldini. Nat Rev Gen 2009). We also developed the first genome-wide technology to measure miRNA activity and function at single cell resolution (Mullokandov, Baccarini, Ruzo et al. Nat Meth 2012), and aided in the invention of an improved method for deep sequencing small RNAs (Jayaprakash et al. Nucl Acid Res 2011). We helped develop a new platform for predicting the immune systems response to 100s of drugs (Kidd, Wroblewska et al. Nat Biotech. 2016).
Postdoctoral and graduate projects are available involving: (i) cancer immunology and immunotherapeutics, (ii) the discovery of novel gene expression networks in the immune system, and (iii) the development of novel technologies and therapeutics.
