Unstimulated / (Left panel) and 10 μg/ml phytohemagglutinin (PHA)-stimulated (2 days) / (Right panel) peripheral blood mononuclear cells were stained with Alexa Fluor® 647 Mouse Anti-Human CD3 and FITC Mouse Anti-Human CD134 Antibody at 5μl/test. Flow cytometry and data analysis were performed using BD FACSymphony™ A1 and FlowJo™ software.

Background
CD134, also known as OX40 or tumor necrosis factor receptor superfamily member 4 (TNFRSF4), is a type 1 transmembrane glycoprotein and a secondary co-stimulatory immune checkpoint molecule involved in long-term T cell immunity. It is transiently expressed on activated CD4+ and CD8+ T cells after T cell receptor (TCR) ligation. The interaction between CD134 and its ligand, OX40L, enhances T cell activation, proliferation, survival, and cytokine production. CD134 is crucial for maintaining an immune response beyond the initial activation phase and is being investigated as a target in cancer immunotherapy, autoimmune disease modulation, and vaccine development.
