background: cationic immune stimulating complexes (pluscoms) are particulate antigen delivery systems. pluscoms consist of cationic immunostimulatory complexes (iscoms) derivatives and are able to elicit in vivo t cell responses against an antigen. objective: to evaluate the effects of pluscoms containing leishmaniamajor antigens (sla) on the type of immune response generated in the murine mode...

lactic acid bacteria which are  used  as  probiotics  have  ability to  modulate  immune responses and modify immune mechanisms. it has also been indicated that some strains of this family can affect the immune responses against solid tumors. in the present work, we proposed to study the effects of oral administration of l.cacesi ssp casei on the nk cells cytotoxicity and also production of cyt...

Background: Hepatitis C (HCV) is a worldwide problem without an effective vaccine with more than 170 million chronically infected people worldwide. DNA vaccines expressing antigenic portions of the virus with adjutants have recently been developed as a novel vaccination technology. Objectives: In the present study, a DNA vaccine expressing HCV core protein was developed with IL12 as a genetic a...

high morbidity and mortality of influenza virus infection makes it an important disease world-wide. mouse is a very well-studied animal model for this disease with similar manifestation to human disease. it would be desirable to induce mucosal as well as circulating immune responses to obtain protection from infection and to decrease the spread of the virus. cell mediated immunity (proliferativ...
