| Abstract: | The distribution of liposomes prepared from total mouse liver lipids and containing (3H)-labelled platelet activation factor in mouse organs was studied. It was shown that the majority of intraperitoneally injected liposomes prepared from total mouse liver lipids were transported to mouse liver and spleen. The interaction of liposomes with spleen cells in vitro revealed that the affinity of liposomes prepared from total spleen macrophage or total spleen lymphocyte lipids for mouse spleen cells was much higher than that of liposomes prepared from a model lipid mixture. The liposome binding to isolated spleen macrophages or lymphocytes was much higher than the liposome uptake by these cells in the total population of mouse spleen cells. |
