Abstract：
:Autophagy is considered as an important intracellular mechanism that degrades cytoplasmic components to furnish additional energy. It has cytoprotective effects through the degradation of intracellular pathogens, damaged organelles, and protein aggregates. On the other hand, there are reports of an association between autophagy and autoimmune diseases. Indeed, it has been evident that autophagy is dysregulated in various autoimmune diseases including rheumatoid arthritis (RA). Autophagy is implicated in the maturation survival and proliferation of various immune and non-immune cells, which play pivotal roles in RA pathogenesis. Additionally, autophagy seems to be involved in citrullination and presentation of citrullinated peptides to T lymphocyte cells. Presentation of citrullinated peptides through MHC compartments to the T cells leads to immune response and chronic inflammation. Evidence suggests that autophagy could be implicated in apoptosis resistance of RA fibroblast-like synoviocyte (RA FLS), osteoclastogenesis, and finally severe bone and cartilage destruction. Since autophagy could be an important phenomenon in RA pathogenesis, we summarized the roles of autophagy in citrullination, osteoclastogenesis, RA FLS cells survival, apoptosis resistance of cells, lymphocyte homeostasis and its clinical outcomes in RA disease.
