Analysis of the persistence of humoral and cellular immunity in children and adults immunized with varicella vaccine.

Evaluation of humoral and cellular immunity of recombinant autolysin protein Staphylococcus aureus in mouse model

Background: Staphylococcal aureus is a gram positive cocci and opportunistic pathogen. Due to the spread of this bacterium to antibiotics resistance, one of the most important ways of prevention is the use of vaccines. In this respect, autolysin protein as one of the adhesion molecule of bacteria plays an important role for binding bacteria to the host cells and cell division. Herein, the role ...

القای ایمنی هترولوگ علیه سویه‌های رایج آنفلوانزا با استفاده از واکسن ژنی بر پایه قطعه HA2

Background: Problems of live and inactivated influenza vaccines such as, increasing emerge and re-emerge viruses with high human mortality, current epidemics of influenza and direct transmission of avian viruses to human, affect the vaccination program. DNA vaccines as third generation of vaccines is specially considered for control of influenza in human and poultry. The main advantage of these...

An HIV-1 Mini Vaccine Induced Long-lived Cellular and Humoral Immune Responses

Memory formation is the most important aspect of a vaccine which can guarantee long-lasting immunity and protection. The main aim of the present study was to evaluate the memory immune responses after immunization with a mini vaccine. Mice were immunized with human immunodeficiency virus-1 P24-Nef fusion peptide and then cellular and humoral immune responses were evaluated. In order to determin...
