Immune System (Local Immunomodulation)

Local immunomodulation refers to the targeted manipulation of immune responses within a specific tissue or microenvironment. It aims to enhance therapeutic efficacy and reduce systemic side effects by focusing immune modulation at the site of disease or intervention. This strategy involves localized delivery or modification via biomaterials, nanoparticles, or genetic engineering to affect key immune cells (T cells, B cells, dendritic cells, macrophages) and molecules (cytokines, chemokines) influencing local immune balance. The goal is to achieve site-specific action while minimizing systemic toxicity and the risk of broad immunosuppression or activation.
