IL-13

IL-13 is a cytokine secreted by T cells and mast cells that is involved in several immune system responses, including allergy and asthma pathogenesis. IL-13 is known to induce the production of IgE antibodies, which play a crucial role in the allergic response.

Function

IL-13 is a key mediator of inflammation and tissue remodeling. It is involved in the pathogenesis of several diseases, including asthma, allergy, and autoimmune diseases. IL-13 acts by binding to its receptor, IL-13R, which is expressed on a variety of cells, including B cells, eosinophils, fibroblasts, and smooth muscle cells.

Role in Disease

IL-13 has been implicated in a number of diseases. In asthma, IL-13 is thought to contribute to airway hyperresponsiveness and mucus production. In allergy, IL-13 is involved in the production of IgE antibodies, which are responsible for the allergic response. In autoimmune diseases, IL-13 has been shown to promote the production of autoantibodies.

Therapeutic Potential

Given its role in disease, IL-13 is a potential target for therapeutic intervention. Several drugs that target IL-13 or its receptor are currently in development for the treatment of asthma and other diseases.
