OX40/TNFRSF4 Antibody (OX-40) Summary

Phytohemagglutinin (PHA) activated Rat Lymph Node Cells
Cell Membrane. Type I membrane protein.
NB100-65293 recognizes the OX40 antigen which is present on activated T lymphocytes that also express CD4 (1). The antigen is a glycoprotein of approximately 50kD molecular weight which is related in sequence to the low affinity Nerve Growth Factor Receptor (2). Clone OX-40 is not mitogenic, but does enhance some T cell responses (1).

The OX40 receptor is also known as CD134, ACT35, and tumour necrosis factor receptor superfamily member 4. This receptor is expressed on activated CD4+ and CD8+ T cells and B cells. The OX40 receptor binds to the OX40 ligand to provide a co-stimulatory signal that is independent of CD28. Blockade of OX40-OX40 ligand interactions has been shown to ameliorate experimental EAE and inflammatory bowel disease, imply that these interactions are important in the pathogenesis of some autoimmune diseases.
