Methods of stimulating or enhancing an immune response in a host are disclosed. The methods include contacting a monocyte with 15 kD granulysin thereby producing a monocyte-derived dendritic cell. In one example, the method further includes contacting the monocyte or monocyte-derived dendritic cell with a target antigen, such as a tumor antigen or an autoimmune antigen. In another embodiment, the method includes contacting the monocyte with an additional agent that enhances maturation of dendritic cells or induces immunological tolerance. The methods are of use in vivo, in vitro and ex vivo. In another aspect, the disclosure relates to compositions and methods for the treatment of tumors. 1. A method of enhancing an immune response against a target antigen , comprising administering to a subject in need thereof:(a) a therapeutically effective amount of the target antigen and a monocyte-derived dendritic cell produced by contacting a monocyte with an effective amount of 15 kD granulysin; or,(b) co-administering the target antigen and the 15 kD granulysin to the subject.2. The method of claim 1 , further comprising contacting the monocyte with an additional agent other than 15 kD granulysin that enhances dendritic cell maturation.3. The method of claim 2 , wherein the additional agent that enhances dendritic cell maturation comprises GM-CSF claim 2 , M-CSF claim 2 , IL-4 claim 2 , IL-6 claim 2 , IL-7 claim 2 , IL-13 claim 2 , flt-3L claim 2 , TNF-α claim 2 , IFN-α claim 2 , CpG motif containing oligonucleotides claim 2 , toll-like receptors claim 2 , heparan sulfate claim 2 , calcium ionophore claim 2 , or a combination thereof.4. The method of claim 1 , wherein the target antigen comprises a protein claim 1 , a polypeptide claim 1 , a polysaccharide claim 1 , a lipid claim 1 , a DNA molecule claim 1 , a RNA molecule claim 1 , a whole cell lysate claim 1 , an apoptotic cell claim 1 , a live claim 1 , attenuated claim 1 , or heat-killed antigen claim 1 , or a ...
