... Cytokines perform this function. Cytokines regulate local and systemic immune and inflammatory responses as well as wound healing, hematopoiesis and many other biologic activities. A cardinal feature of these secreted proteins is that they have short half-lives, which will typically restrict communication to those cell types within lymphoid tissues and at sites of inflammation. Therefore, therapies that regulate the activity of inflammatory cytokines, either by supplementation of anti-inflammatory recombinant cytokines or by neutralizing them by using blocking antibodies, have been extensively used over the past decade⦠1.
