Cytokine Engineering Approaches for Regenerative Medicine

The document explores cytokine engineering strategies for regenerative medicine, highlighting their role in tissue repair and immune response modulation. Despite challenges like pleiotropy and poor pharmacokinetics, advances in protein engineering have led to modified cytokines with improved stability, receptor selectivity, and tissue-targeting capabilities. Strategies such as PEGylation, Fc fusion, and ECM-binding motifs enhance cytokine stability and efficacy. Engineered cytokines, including partial agonists and multimeric complexes, aim to reduce off-target effects and promote tissue healing. The document also discusses the potential of immunocytokines and cytokine prodrugs to enhance precision and safety in therapies. While challenges in clinical translation persist, these advancements hold promise for treating chronic wounds, fibrotic diseases, and tissue injuries with limited regenerative capacity.
