Development and Regulation of IL-17 Producing Cells During Inflammation

The immune system has evolved to protect mammals from environmental stress factors such as pathogens. It functions as a fine-tuned consortium of effector units and suppressors. However, under certain pathologic conditions effector units may escape control and start to attack their own body. This leads to the development of autoimmune diseases, such as multiple sclerosis (MS). We use molecular and genetic tools such as Cre-recombinase and Cre/loxP, microscopy, next generation sequencing (including single cell sequencing and ATAC-seq), proteomics, and high dimensional flow cytometry to study the cellular and molecular mechanisms of MS pathology.

The lab is also interested in studying the role of the deubiquitinating (DUB) enzymes A20 and CYLD in the ageing process. To this end, we study how deletion of these DUB enzymes specifically in glia cells affects the ageing of the brain.
