Cytokines are small proteins which direct the development, differentiation and regulation of immune cells. As a result, dysregulation of cytokine production or action is thought to have a central role in the development of autoimmunity and autoimmune disease. Antibodies which block cytokine receptor signaling in vivo are invaluable for understanding cytokine function and creating new therapies to treat autoimmunity. Bio X Cell offers a plethora of cytokine receptor blocking antibodies for your research needs. For information on cytokine neutralizing antibodies see the cytokine and chemokine product category.
