 AB    Liposomes have been proposed as vehicles for vaccines against parasitic
       and viral illnesses. Experimental vaccines against malaria, HIV,
       hepatitis A, and influenza virus have been shown to be safe and highly
       immunogenic in several human trials. Analysis of the intracellular
       trafficking patterns of liposomal antigen reveals that after being
       phagocytosed by macrophages, liposomal antigen readily escapes from
       endosomes into the cytoplasm of the macrophages. It is proposed that
       liposomal peptide antigen can enter either the Golgi apparatus or the
       endoplasmic reticulum and thereby interact with MHC class II or class I
       molecules. The intracellular cytoplasmic trafficking patterns of
       liposomal antigens raise the possibility that liposomes may have utility
       in human vaccines for induction of either humoral immunity or cytotoxic
       T lymphocytes.
