Description
Thymus and activation- regulated chemokine (TARC) is a recently identified CC chemokine that is expressed constitutively in thymus and transiently in stimulated peripheral blood mononuclear cells. TARC functions as a selective chemoattractant for T cells that express a class of receptors binding TARC with high affinity and specificity.The chemokine TARC is a ligand for the chemokine receptor CCR4 expressed on T helper (Th) 2- type CD4 T cells
