Abstract
The majority of autoimmune diseases are multi-factorial diseases that develop through the interaction of several factors, such as genetic and environmental factors. A limited number of disease susceptibility genes, including those of the major histocompatibility complex have been known to exist for several decades. After these eras, genome-wide association studies have been used for more than 10 years to identify susceptibility genes for certain autoimmune diseases. These findings have contributed to our understanding of the pathogenesis of these diseases. As the analysis of susceptibility genes has progressed, it has become apparent that many disease susceptibility gene variants are involved at the expression level of genes. Furthermore, expression of genes related to disease pathogenesis is cell-specific, with involvement of epigenetic mechanisms. Genetic information exists before the onset of disease, and thus has a causal relationship to the disease. Therefore, the analysis of genomic function in human immunology research is essential, with regard to understanding the pathological mechanisms as well as having applications for drug discovery. In this article, we discuss these issues, with a particular focus on rheumatoid arthritis.
