Nucleic acid moleucles that encode conjugates containing as a ligand a chemokine receptor targeting agent, such as a chemokine, and a targeted agent, such as a toxin are provided. These conjugates are used to treat inflammatory responses associated with activation, proliferation and migration of immune effector cells, including leukocyte cell types, neutrophils, macrophages, and eosinophils.
