What is OX40 Antibody?
An OX40 antibody targets the OX40 receptor, a protein primarily found on activated T cells. OX40 is a co stimulatory molecule crucial for regulating T cell activation, proliferation, and survival. Binding of its natural ligand, OX40L, delivers a secondary signal essential for robust immune responses, particularly in T helper cells. An OX40 antibody can either block OX40L binding, thereby dampening T cell activity, or act as an agonist, mimicking OX40L to enhance T cell responses. This dual capacity makes OX40 antibodies significant therapeutic agents in oncology to boost anti tumor immunity and in autoimmune diseases to suppress undesirable immune activity.
