Systems Immunology

HOME > People > Systems Immunology

The Systems Immunology Lab is actively pursuing two major immunology research themes: analysis of immune repertoire sequence data and post-transcriptional regulation of immune responses. In addition, we are developing several core bioinformatics methods, including the MAFFT multiple alignment platform (Katoh, K. & Standley, D. M. Mol Biol Evol (2013)) and the OSCAR protein modeling force field (Liang, S. et al. Bioinformatics 27, 2913-2914 (2011)).

For analysis of immune repertoires, we have taken a structure-based approach. First, we developed a method for high-throughput B cell receptor modeling from sequence data (Yamashita, K. et al. Bioinformatics (2014)). We are currently utilizing sequence and structural features to predict the phenotype of B and T cell receptors in order to develop novel biomarkers and therapeutics.

With regard to post-transcriptional regulation, we are interested in molecular mechanism by which RNA-binding proteins (RBPs) regulate gene expression in immune cells. In order to study RBP-RNA interactions computationally, we have developed a tool for predicting RNA binding sites on proteins (Li, S. et al. Nucleic Acids Res (2014)) and for carrying out flexible protein-RNA docking (Nyati, K. K. et al. Nucleic Acids Res (2017)). These tools have recently been used to investigate the immune-regulatory roles of the RBPs Regnase-1 (Mino, T. et al. Cell (2015)) and Arid5a (Masuda, K. et al. J Exp Med (2016)).
