In recent years, the incidence rate has increased significantly worldwide and caused a huge burden of disease. Immune response, including congenital immune response and adaptive immune response, plays a vital role in regulating human health and disease. Similarly, in the onset of IBD, its inflammatory cells and cytokines also play an extremely important regulatory role. This article reviews the research progress of IBD immune response and regulatory mechanism in recent years, with a view to providing new ideas and strategies for the research and treatment of IBD.展开更多
