Naked DNA and DNA-LNP mediated detectable GFP activation in the skin and draining lymph node in some mice, but this activity was low and did not reach statistical significance when compared to PBS-treated animals. mRNA-LNPs and Ad both mediated significant Cre delivery in CD45 + , CD3 + , CD11b + , and CD207 + immune cells in the skin and in the lymph node, with adenovirus mediating consistently higher levels of expression in all of the tested cells.
