Abstract
Novel methods for rapidly generating dendritic cells are disclosed herein. The methods include contacting a dendritic cell precursor with a D ODN to generate a mature dendritic cell. In one specific, non/limiting example, the method includes contacting the dendritic cell precursor or the mature dendritic cell with an antigen. The methods are of use both in vitro and in vivo.
