oh-ex-forty / oh-ex-forty-ligand
A co-stimulatory receptor-ligand pair that enhances T cell activation, survival, and memory formation.
OX40 agonism triggers pro-survival and activation pathways:
The net effect is a more robust and sustained T cell response against tumor antigens.
What It Does: OX40 signaling tells T cells to stay alive longer, multiply more, and fight harder. It's like giving them energy drinks instead of tranquilizers.
OX40 agonists are being tested in combination with checkpoint inhibitors:
Functional measurement of OX40/OX40L engagement could potentially identify patients with activatable T cells in the tumor.
Combination Approach: Checkpoint blockers remove the brakes on T cells. OX40 agonists press the accelerator. Both together may work better than either alone.
