PTPRZ1

Colony-stimulating factor 1 (CSF-1), also known as macrophage colony-stimulating factor, is one of the most common proinflammatory cytokines leading to a variety of inflammatory diseases. It plays a significant role in the development and progression of osteoarthritis, cancer, and other autoimmune diseases. CSF-1 exerts its effects by binding to a receptor called colony stimulating factor 1 receptor (CSF-1R), also known as c-FMS, leading to a signaling pathway cascade, resulting in cell proliferation and differentiation. Although CSF-1R appears to be the only receptor for CSF-1, IL-34 additionally binds to receptor protein-tyrosine phosphatase-zeta (RPTP-ζ) and the expression pattern of the ligand is also different. CSF-1R/c-FMS is overexpressed in macrophages within many tumors, and thus has been used as a promising target for drug treatment of cancer and inflammatory diseases. Some CSF-1R/c-FMS inhibitors, such as ABT-869, Imatinib, AG013736, JNJ-40346527, PLX3397, DCC-3014, and Ki20227 have been used to study the treatment of these diseases. CSF-1R inhibitors work by binding to CSF-1R, preventing active cells from the body from signaling, thereby impeding the progression of diseases. In recent years, scientists have explored a series of CSF-1R-targeting drugs based on this target. The research status of related products is mostly at the clinical phase I. Strategies for targeting CSF-1R can be divided into two types. They can use large molecule antibodies to target its CSF-1 ligand, or CSF-1R receptor, or design small molecules to target the kinase active region.
