"The image shows delivery of vesicular vaccine-containing nanoparticles (blue) to mouse skin, colocalizing with antigen presenting dendritic cells (APCs-green).  These nanoparticles have recently been shown to have significant potency for generation of cell- and antibody-base immunity.  The image was intended to show the delivery of vaccine-containing particles to APCs, as this is the first step for generation of vaccine-mediated immunity.

This image is representative of a series of steps in the validation of this materials system as a potent platform for immunization.  Demonstrating delivery, and subsequent interaction of these materials to the immune cell populations of interest is an important piece of evidence for understanding of the mechanism by which these materials generate such powerful immunity."
