Cytoki’s lead program is an engineered long-acting IL-22 protein licensed from a major pharmaceutical company.A correctly functioning immune system is essential for keeping us healthy in the multitude of challenges our organism encounters. Numerous medicines are based on principles that activate or deactivate key proteins in the immune system in a disease context. IL-22 is a key cytokine (a class of proteins released from immune cells) in securing the survival and repair after an injury. It is the immune system’s “Survive and Recover” signal to the tissue. Our lead program is harnessing the power of IL-22, in treatment of organ injuries, through a modified IL-22 protein engineered to have optimal pharmaceutical properties.
