IL-26(Interleukin 26) is a member of the interleukin family, plays a crucial role in immune response, particularly in regulating inflammation and activating T cells. IL-26 is primarily secreted by activated T cells and has been implicated in various inflammatory diseases, making IL-26 an important target for therapeutic intervention. IL-26 interacts with specific receptors on target cells, leading to the activation of signaling pathways that promote pro-inflammatory cytokine expression. Understanding IL-26 function and interactions is vital for developing strategies to modulate immune responses in conditions such as autoimmune diseases and chronic inflammation.
