Emerging roles of SLAMF7 in immune cells and related diseases.

Abstract

Immune cells are heterogeneous and perform different functions in different microenvironment, thus playing different roles in different stages of diseases. Studies have shown that immune cells are involved in the pathogenesis of many diseases, and there is a causal association of immune cells with disease states. Signaling Lymphocyte Activation Molecule family (SLAMF) members are a newly appreciated group of specific receptors that are mainly expressed in immune cells and whose role is to regulate the function of immune cells. SLAMF7, also known as CD319, has been widely reported in multiple myeloma, and in recent years, more and more studies have shown that SLAMF7 is widely involved in the function of immune cells and the progression of breast cancer, acquired immune deficiency syndrome, systemic lupus erythematosus and other immune cells-related diseases. However, the mechanisms underlying the regulatory role of SLAMF7 on immune cells, and the impact on the progression of immune cells-related diseases remain poorly elucidated. In this review, we summarize current knowledge about the role of SLAMF7 in immune cells and related diseases such as cancer, infectious disease, autoimmune disease and atherosclerosis, and the therapeutic strategy targeting SLAMF7 is also described. By better understanding the role and regulation of SLAMF7, we hope to provide new insights and directions for improving the diagnosis and treatment of inflammation.
