PPT-Cytokines receptors and biological functions

Cytokine Receptors These are the receptors present on membrane of responsive target cells by which cytokines binds to exert their biological effects Cytokine Receptors Fall Within Five Families.

Cytokines despite being nonspecific immunity it regulate the intensity and duration of the inflammatory/immune response.. Most cytokines are single polypeptide chains, may be aggregate as a homotrimer e.g. IL-12, IL-23. ®.
