When MNPs are delivered into human body, they are ingested by macrophages. We evaluated the cellular response of macrophage after MNPs loading. In face of stimulation by lipopolysaccharide, a strong stimulant derived from bacterial cell wall, MNPs loaded macrophage exhibited decreased phagocytic activity and decreased generation of cytokines such as TNF-, IL-1 whereas increased nitric oxide generation was noticed. Although these changes might decrease bactiericidal activity, it also alleviates the risk of senses, a life threatening phenomenon in infection patients. The finding has significant implications on nanoparticle based targeted drug delivery.", }
