Abstract |
Trans-follicular (TF) vaccination has recently been studied as a unique route for non-invasive transcutaneous vaccination. The present study aims to extensively characterize the immune responses triggered by TF vaccination using ovalbumin loaded chitosan-PLGA (poly lactic-co-glycolic acid) nanoparticles without skin pre-treatment to preserve skin integrity. The impact of formulation composition i.e. antigenic solution or antigen-loaded nanoparticles with or without adjuvant [bis-(3',5')-cyclic dimeric adenosine monophosphate] on immune response quality following TF immunization was analyzed and compared with immune responses obtained after tape stripping the skin. The results presented in this study confirm the ability of nanoparticle based vaccine formulations to deliver antigen across the intact skin via the follicular route, but at the same time demonstrate the necessity to include adjuvants to generate efficient antigen-specific humoral and cellular immune responses. |
