Abstract:
:In view of its potent inhibitory capacity on immune cells in culture, we wished to determine the ability of transforming growth factor (TGF) beta 1 to down-regulate immune responses in vivo. Preliminary experiments suggested that, at the doses used, systemic injection of soluble TGF beta 1 could not affect bacterial-induced spleen enlargement in mice. Therefore, we sought to utilize a physiochemical property of this molecule, namely its high pI, to determine possible association between the ligand and preformed liposomes possessing an opposite charge. TGF beta 1 was preferentially associated with negatively charged, but not with neutral, liposomes. These TGF beta 1 associated liposomes were able to deliver a suppressive signal to indicator cells in vitro. Intravenous injection of TGF beta 1, associated with liposomes possessing an opposite charge, into mice immunized with heat-killed Corynebacterium parvum significantly reduced the size of the spleen as well as the number of splenocytes. Systemically administered TGF beta 1 associated liposomes could also inhibit delayed type hypersensitivity reactions to Listeria monocytogenes. These data suggest that appropriately administered, TGF beta 1 can inhibit immune responses in vivo.
