Aim:
The aim of this study is to investigate the effects of constructed dendritic cell (DC)-based DNA vaccine (pRSC-NLDC145.gD-IL21) carried by chitosan nanoparticle in preventing primary or recurrent herpes simplex virus keratitis (HSK) in mice.
Methods:
The expression of constructed plasmid 'pRSC-NLDC145.gD-IL21' was verified by western blot and immunofluorescence. Plasmids that were embedded in chitosan were inoculated to test its therapeutic effect against primary or recurrent HSK in mice. Humoral and cellular immune response, clinical scores of herpes keratitis and inflammatory infiltration were measured.
Results:
The expressed glycoprotein D (gD) of pRSC-NLDC145.gD-IL21 DNA/chitosan nanoparticle vaccine could effectively target corneal DCs and significantly alleviate the symptoms of both primary and recurrent HSK mice via eliciting strong humoral and cellular immune response.
Conclusion:
Our data suggested that DC-based DNA vaccine could be a better choice for HSK treatment in the future.

Airborne precautions:
Use airborne precautions when treating patients known or suspected to have diseases that spread through the air—for example, tuberculosis or measles. These organisms are present in smaller droplets expelled by an infected person and...
