摘要: A human MUC1-transfected mouse mammary adenocarcinoma cell line (GZHI) was used to develop both subcutaneous and intravenous tumor models. vaccine formulation comprised of a 24 mer (human MUC1) synthetic peptide encapsulated with monophosphoryl lipid adjuvant (MPLA) in multilamellar liposomes tested for immunogenicity anti-tumor activity. low dose the MUC1 (5 microg) administered provided excellent protection mice challenge The protective antitumor activity mediated by liposome correlated anti-MUC1-specific T-cell proliferation, gamma-interferon (IFN-gamma) production IgG2a anti-MUC1 antibodies, suggesting type 1 (T1) response. In contrast, lack immunized negative control vaccines IgG1 anti-MUCI antibody formation, or no antigen-specific consistent 2 (T2) response tumor.
