Interleukin-7 (IL-7), a member of the cytokine family related to IL-2, stimulates the survival, proliferation, and homeostasis of T cells via the gamma c (γc) subunit of the receptor. IL-7 can replace IL-2 for activating T cells and avoid the immune tolerance due to Treg activation by IL-2. Studies have shown that IL-7 can expand antigen-specific T cells in vaccine injection or cell therapy, in addition, IL-7 is able to promote T cell recovery after chemotherapy or hematopoietic stem cell transplant. Recombinant Human IL-7 is expressed by mammalian cells, and is produced with raw materials of pharmaceutical applicable level. The host protein residue, nucleic acid residue and common pathogens are strictly controlled, and the production and quality management procedures of the product comply with GMP regulations to ensure the traceability of the production process and all raw materials.
