Liposomes in immunology: further evidence for the adjuvant activity of liposomes.
The immune response to HSA-phosphatidylcholine complexes administered to rabbits was not markedly enhanced when compared with the response to unmodified HSA. It was found in earlier work that HSA entrapped in liposomes (mainly composed of phosphatidylcholine) evoked a strong immune response under conditions where no response was detected to free HSA. The present results exclude the possibility that HSA-phosphatidylcholine complexes which may arise from liposome-encapsulated HSA may be responsible for the adjuvant activity of the liposome. The adjuvant activity of liposomes could also be established after administration of a liposome-associated strong antigen (BGG).
