Abstract: Dengue Fever (DF) Virus-based Vaccine development showed a relatively slow progress because it should induce protection against the 4 serotypes of Dengue Viruses and there is a very limited adequate animal model for dengue virus infection. In the last decade, new approach in vaccine development for arthropode-borne diseases is using salivary vector components. This approach based on hyphotesis that arthropode vectors saliva contains vasomodulator and imunomodulator proteins that could enhance pathogen infection. Therefore, it should be possible to control pathogen transmission by vaccinating the host against the molecule(s) in saliva that potentiate the infection, thereby blocking the enhancing effects of saliva and thus preventing the pathogen from establishing infection in the host (Transmission Blocking Vaccine, TBV). However, specific component as a potential target for TBV in Aedes aegypti, as major vector for DF has not yet been identified so far. This paper wanted to elaborate the immunogenic components from Salivary Gland (SG) of Aedes aegypti as potential immunomodulatory protein. We have characterized 2 immunogenic proteins that are only recognized by healthy people living in endemic area and not by people from non-endemic area. They have molecular weight of 31 & 56 kD. Further molecular characterization by Mass-Spectrophotometry of those proteins showed that 31 kDa and dan 56 kDa have high similarity with D7-Protein Family (Odorant Binding Protein) & Apyrase, respectively. These proteins have very important role in vector blood feeding process. This also supported by the strong immunogenicity of 31 kDa against human sera in healthy people as well as Dengue patients. The apyrase activity of 56 kD protein has also been proven in this research.
