Figure 4From: Intranasally administered protein coated chitosan nanoparticles encapsulating influenza H9N2 HA2 and M2e mRNA molecules elicit protective immunity against avian influenza viruses in chickensHA2 and M2e mRNA cell delivery and expression by CNPs. THP-1 cells were treated with empty CNPs, CNPs delivering HA2 mRNA, or CNPs delivering M2e mRNA. After 16 h, the cells were visualized under a confocal microscope (Scale bar: 20 µM). The experiment was repeated twice. The results shown represent one independent experiment.Back to article page
