GelMA-Macrophages-LED system
Delivery StrategyThe GelMA-Macrophages-LED system is a composite delivery harness composed of a light-crosslinked GelMA hydrogel, gene-modulated macrophages, and a wireless LED device. In the cited study, it was used for in situ light regulation of cardiac inflammation in murine lipopolysaccharide-induced sepsis models, with macrophage photoactivation linked to suppression of inflammatory cytokine production.
