Abstract

Successful delivery of labile vaccine antigens, such as peptides and proteins, to stimulate CD4 and CD8 T cell immunity could improve vaccine strategies against chronic infections such as HIV and Hepatitis C. Layer-by-layer (LbL)-assembled nanoengineered hydrogel capsules represent a novel and promising technology for the protection and delivery of labile vaccine candidates to antigen-presenting cells (APCs). Here we report on the in vitro and in vivo immunostimulatory capabilities of LbL-assembled disulfide cross-linked poly(methacrylic acid) (PMASH) hydrogel capsules as a delivery strategy for protein and peptide vaccines using robust transgenic mice models and ovalbumin (OVA) as a model v..
