Talk Summary 

CD8 T cells play an essential role in defense against viral and bacterial infections, but can fail to mount protective responses in chronic infections and cancer progression. The conspicuous heterogeneity of CD8 T cell states raised a question of their common and unique characteristics in different experimental and clinical settings. We uncover remarkably recurrent chromatin and transcriptional features for CD8 T cell progression towards dysfunctional states in cancer and infection through a comprehensive analysis of 302 bulk ATAC-seq and RNA-seq experiments from 12 studies and new scATAC-seq and scRNA-seq data. We also study CD8 T cell dysfunction in a double-transgenic mouse model of self-tolerance, using DNase-seq and RNA-seq data, and identify a unique epigenetic signature of the self-tolerant state. These results provide a better understanding of basic mechanisms of adaptive immunity and can lead to better strategies for treatments of both solid organ and hematologic malignancies and chronic infections.

 

Biography

Yury Pritykin is a postdoctoral researcher in Computational and Systems Biology Program at Memorial Sloan Kettering Cancer Center. He received his M.Sc. and Ph.D. degrees in Mathematics from Lomonosov Moscow State University and a Ph.D. in Computer Science from Princeton University. His main interest and expertise is in using applied statistics, machine learning, and efficient computer algorithms to address fundamental problems in biology and medicine by integrative analysis and interpretation of multi dimensional data.  His specific goal is to leverage functional genomics and other high-throughput molecular assays at the bulk and single cell level in order to obtain a systematic  molecular understanding of immune cell function in health and disease and address critical problems in cancer immunology and immunotherapy.
