The Signaling Pathway of PGE₂ and Its Regulatory Role in T Cell Differentiation

Figure 2

The signaling pathway of PGE₂. The schematic diagram shows the downstream signaling pathway of PGE₂. The lipid mediator actives or inhibits the target cell via four EP receptors, EP1, EP2, EP3, and EP4. Different receptors activate different signaling pathways which are connected in a network in the cell and cooperate with each other in vital processes.
