| Abstract | |
The development of mucosal immunogenic vaccines is essential to prevent HIV infection. The LAMP/gag vaccine strategy associates the murine LAMP gene and the HIV-1 gag gene, allowing antigenic presentation in the context of MHC class II molecules. The results showed that the immunization with LAMP/gag chimera DNA vaccine induced anti-GAG sIgA and IgG antibodies and the association of intradermal injection to the intranasal immunization protocol induced anti-GAG antibodies. Both LAMP/gag and gag vaccines generated a strong CD8+ T-cell response. However, the CD4+ T cells response was more pronounced in LAMP/gag mice, able to recognized twice the number of GAG peptide pools and increasing the amplitude of IFN-<font face=\"symbol\">g and IL-4 SFC. The association of the CpG ODN adjuvant to the DNA vaccines downregulated the CD4+ T cells response and the IgG2a antibodies production. The data showed that only the LAMP/gag chimera DNA vaccine was able of inducing cellular and humoral immune responses and immunological memory due to the adequate CD4+ T cells activation. (AU) | |
