Epigenetics and treatment of systemic lupus erythematosus

Abstract

Systemic lupus erythematosus (SLE) is a disease associated with an impaired autoimmune response; the immune system attacks erroneously own tissues, which leads to inflammation, tissue damage and complement activation. The latter plays a pivotal role in SLE pathology, as complement level is suited as histological marker for disease diagnoses and management. Besides, environmentally factors have been highlighted and their significant contribution for individual genetic predisposition has been pointed out. Here complement factors, their activity and their ability to modify DNA with histone proteins are reviewed; known gene mutations involved in SLE, and new therapeutic approaches suggested for SLE are discussed and summarized, as well.
