Epigenetic regulation of HLA genes asociated with celiac disease
Hudec, Michael ; Černá, Marie (advisor) ; Hušáková, Markéta (referee)
Introduction: HLA class II system presents one of the most important mechanism in immune system, which is able to recognise pathogens and damaged cells. Some HLA class II alleles are associated with autoimmune diseases, for example celiac disease, which is typical by chronic inflammation of small intestine and other following symptoms. The risk HLA class II variants are DQ2 and DQ8. Epigenetic mechanisms that regulates gene expression, especially methylation of cytosine in promoter region of DQ2 and/or DQ8 alleles, could have influence on development of T lymphocytes in the thymus, where T-lymphocytes develop and pass a few stages in, and only the survival clones can be part of function immune system. Aim: The aim of this study is to compare methylation level of promoter regions of HLA DQ2 and DQ8 alleles between celiac patients and healthy controls. Another goal is to compare expression level of DQ2 and DQ8 variants between these two groups. Methods: DNA and RNA were isolated from full blood of two sets of donors. DNA was converted by bisulphite conversion and then amplified by Nested PCR. The PCR product was cloned to bacteria. Than positive colonies were selected. Subsequent methylation analysis was performed. RNA was converted to cDNA by Reverse transcription. Relative expression was analyzed...
