title: Evaluation of humoral and cellular immune responses against HSV-1 using genetic immunization by filamentous phage particles: a comparative approach to conventional DNA vaccine.
abstract: Phage display is based on expressing peptides as a fusion to one of the phage coat proteins. To date, many vaccine researches have been conducted to display immunogenic peptides or mimotopes of various pathogens and tumors on the surface of filamentous bacteriophages. In recent years as a new approach to application of phages, recombinant bacteriophage lambda particles were used as DNA delivery vehicles to mammalian cells. In this study, recombinant filamentous phage whole particles were used for vaccination of mice. BALB/c mice were inoculated with filamentous phage particles containing expression cassette of Herpes simplex virus 1 (HSV-1) glycoprotein D that has essential roles in the virus attachment and entry. Both humoral and cellular immune responses were measured in the immunized mice and compared to conventional DNA vaccination. A dose-response relationship was observed in both arms of immune responses induced by recombinant filamentous phage inoculation. The results were similar to those from DNA vaccination. Filamentous phages can be considered as suitable alternative candidate vaccines because of easier and more cost-effective production and purification over plasmid DNA or bacteriophage lambda particles.
