Epigenetic Alterations in Cellular Immunity: New Insights into Autoimmune Diseases

Cell Physiol Biochem. 2017;41(2):645-660. doi: 10.1159/000457944. Epub 2017 Feb 8.

Abstract

Epigenetic modification is an additional regulator in immune responses as the genome-wide profiling somehow fails to explain the sophisticated mechanisms in autoimmune diseases. The effect of epigenetic modifications on adaptive immunity derives from their regulations to induce a permissive or negative gene expression. Epigenetic events, such as DNA methylation, histone modifications and microRNAs (miRNAs) are often found in T cell activation, differentiation and commitment which are the major parts in cellular immunity. Recognizing the complexity of interactions between epigenetic mechanisms and immune disturbance in autoimmune diseases is essential for the exploration of efficient therapeutic targets. In this review, we summarize a list of studies that indicate the significance of dysregulated epigenetic modifications in autoimmune diseases while focusing on T cell immunity.

Keywords: Cellular immunity; Epigenetic modifications; Rheumatoid arthritis (RA); Systemic lupus erythematosus (SLE); Systemic sclerosis (SSc); Type 1 Diabetes (T1D).
