Team Genetics of Autoimmunity
What is genetic contribution to autoimmune diseases?
Genetic risk of autoimmune diseases is important to study to find out disease mechanisms, for development of new diagnostic tools and for prediction of disease progress and treatment success.
The main focus of our group is on genetic factors involved in development of human diseases with complex etiology. This group of diseases is characterized by involvement of environmental and genetic factors that influences different pathways, e.g. immunological mechanisms. To determine genetic component of the disease we perform analysis of genetic markers in several loci shown to be linked or associated with these diseases. Rheumatoid arthritis, SLE myositis, IgA nephropathy, asthma, MCTD, multiply sclerosis are subjects of our investigations during last years. We study cytokine and cytokine receptor genes, genes from HLA complex and other genes with functional links to immune responses. We pay special attention to the functionally important genetic markers, shown to affect structure of the molecule or having important control functions. For some of these markers we perform functional genetic studies using mRNA and protein expression analysis. Haplotype analysis and population genetics are also in the area of our interests that give us possibility to compare the role of established genetic factors in different ethnical groups and populations. Our strategy is to combine a translational approach with basic science using analysis of clinical material and exploring new bioinformatics tools.
