pubmed:abstractText |
We have developed a new methodology to examine effector-cell-mediated immune attack using liposomes as targets. Hydrogen-peroxide-associated killing of liposomes was observed with fluorescence intensification microscopy. Liposomes were composed of 98-99 mol % egg phosphatidylcholine and 1-2 mol % dinitrophenyl lipid hapten. Anti-dinitrophenyl IgG antibody was used to opsonize liposomes. Liposomes were loaded with dihydroxymandelic acid (DHMA) and peroxidase. Macrophage- or neutrophil-mediated recognition of liposomes triggers the release of H2O2 and other oxidative products. Upon interaction of H2O2 or OH radical with liposome contents, DHMA dimerizes forming a fluorescent derivative. Our studies indicate that individual living neutrophils and macrophages deposit oxidative products in a heterogeneous fashion among bound targets.
