On behalf of the Organizing Committee, it is with great pleasure that we welcome you to the 2017 International Symposium on Autoimmunity: Epigenomics and Beyond (2017ISAEB), which will be held in the magnificent city of Beijing during April 27-29th, 2017. Autoimmune diseases affect up to 11% of the population when one includes diabetes and thyroid disease. This means that worldwide there are approximately 600 million people that suffer from a breach of tolerance. Autoimmune disorders encompass a spectrum of complex multifactorial diseases characterized by aberrant immunological response against self antigens. A plethora of clinical-pathogenetic elements and characteristics contribute to autoimmune diseases, which is well documented in the recent frontiers of medical researches.
