- anti-CSF1 monoclonal antibody PD-0360324
A humanized immunoglobulin (Ig) G2 monoclonal antibody (mAb) directed against the cytokine colony stimulating factor 1 (CSF1; CSF-1; macrophage colony-stimulating factor; M-CSF), with potential immunomodulating and antineoplastic activities. Upon administration, anti-CSF1 monoclonal antibody PD-0360324 targets, binds to and neutralizes CSF1. This prevents the binding of CSF1 to its receptor CSF1R (CD115; M-CSFR), which is expressed on various immune cells, such as monocytes and macrophages. This prevents CSF1R activation and CSF1R-mediated signaling in these cells, leading to inhibition of monocyte differentiation, blocking the activity of macrophages, and reducing their production of inflammatory mediators, which reduces inflammation. By blocking the activity and proliferation of CSF1R-dependent tumor-associated macrophages (TAMs) in the tumor microenvironment, PD-0360324 reduces TAM-mediated immune suppression, decreases regulatory T cells (Tregs), re-activates the immune system, and improves anti-tumor cell responses mediated by increasing infiltration by cytotoxic T cells. TAMs play key roles in immune suppression, and tumor cell proliferation and survival. CSF-1 plays a key role in the regulation of the proliferation, differentiation and survival of monocytes and macrophages. Check for active clinical trials using this agent. (NCI Thesaurus)
