Natural killer T (NKT) cells are known to play a role against certain microbial infections, including malaria and HIV, two major global infectious diseases. Strategies that can harness and amplify the immunotherapeutic potential of NKT cells can serve as powerful tools in the fight against such diseases. 7DW8-5, a novel glycolipid, may be one such tool. The interaction of 7DW8-5 with CD1d molecules...
A number of studies have shown that the natural killer T cell (NKT) ligand α-galactosylceramide (α-GalCer) serves as an adjuvant for various vaccines, including viral vaccines, parasite vaccines and protein vaccines. In this report, we investigated the adjuvant activity of α-GalCer on HIV-1 DNA vaccines in mice. This is a first study to show that α-GalCer can enhance the immunogenicity of DNA vaccines,...
DNA vaccine represents an attractive approach to therapy of chronic hepatitis B virus (HBV) infection because of its ability to generate antigen-specific immunity; nevertheless, there is still a need to increase the potency of DNA vaccine. Mycobacterium tuberculosis heat shock protein70 (HSP70) has both chaperon and cytokine functions, and has been shown to act as an adjuvant when co-administered...
