      | Vaxjo ID | 329 |  
      | Vaccine Adjuvant Name | Poly-ϵ-caprolactone and chitosan nanoparticles |  
      | Description | Poly-ϵ-caprolactone and chitosan nanoparticles (NPs) investigated for their adjuvant effect for hepatitis B surface antigen (HBsAg) and the plasmid DNA encoding HBsAg (pRC/CMV-HBs). They provide a strong humoral adjuvant effect and induce Th1/Th17-mediated cellular immune responses. |  
      | Stage of Development | Research |  
      | Host Species for Testing | Mouse |  
      | Components | poly-?-caprolactone/chitosan nanoparticles (NPs) for hepatitis B surface antigen (HBsAg) and the plasmid DNA encoding HBsAg (pRC/CMV-HBs) |  
      | Structure | Nanoparticles |  
      | Function | Poly-?-caprolactone/chitosan NPs provide a strong humoral adjuvant effect for HBsAg and induce a Th1/Th17-mediated cellular immune responses worth explore for hepatitis B virus vaccination Activates TLR3 and MDA5, and stimulates immune response. [PMC9927404] |
