Immunomodulatory role of spleen tyrosine kinase in chronic inflammatory and autoimmune diseases

Abstract

AbstractBackgroundThe high prevalence of chronic inflammatory diseases or autoimmune reactions is a major source of concern and affects the quality of life of patients. Chronic inflammatory or autoimmune diseases are associated with many diseases in humans, including asthma, rheumatoid arthritis, systemic lupus erythematosus, inflammatory bowel disease and cancer. Splenic tyrosine kinase (SYK) is a non–receptor tyrosine kinase that plays an important role in immune receptor signalling in immune and inflammatory responses.MethodsThis is a review article in which we searched for keywords “splenic tyrosine kinase”, “inflammation” and “autoimmune diseases” in published literature such as Pubmed and Web of Science to collect relevant information and then conducted a study focusing on the latest findings on the involvement of SYK in chronic inflammatory or autoimmune diseases.ResultsThis paper reviews the regulation of Fcγ, NF–κB, B cell and T cell–related signalling pathways by SYK, which contributes to disease progression in chronic inflammatory and autoimmune diseases such as airway fibrosis, inflammatory skin disease and inflammatory bowel disease.ConclusionThis paper shows that SYK plays an important role in chronic inflammatory and autoimmune diseases. syk targets hematological, autoimmune and other inflammatory diseases and therefore, inhibition of SYK expression or blocking its related pathways may provide new ideas for clinical prevention and treatment of inflammatory or autoimmune diseases.
