Chemokine (C-C motif) ligand 22, also known as CCL22 is secreted by dendritic cells and macrophages, and elicits its effects on its target cells by interacting with cell surface chemokine receptors such as CCR4.1 CCL22 selectively chemo-attract Th2 cytokine-producing cells2,3 and acts as an important activator of eosinophils once these cells have migrated into tissue.4

The biological activity of Mouse MDC was determined by its ability to chemoattract human T-lymphoblastoid CEM-NKR cells (Howell, D.N. et al., 1985, J. Immunol. 134: 971 - 976) and to chemoattract mouse BaF/3 cells transfected with hCCR4. The expected ED50 for these effects are typically 5 - 20 ng/ml and 0.5 - 3 ng/ml, respectively.
