Platycodon grandiflorum exosome-like nanoparticles: the material basis of fresh platycodon grandiflorum optimality and its mechanism in regulating acute lung injury

Fresh PG has better anti-inflammatory and repair effects than its dried form. As one of the most effective active substances in fresh PG, PGLNs may regulate macrophage inflammation and polarization by regulating metabolic pathways including lipid metabolism and glycolysis, so as to reduce inflammation and repair lung injury.
