Revvity HTRF Human CCL17 Detection Kit, 50,000 Assay Points

Human CCL17, also known as thymus and activation regulated chemokine (TARC), was initially isolated from phytohemagglutinin-stimulated peripheral blood mononuclear cells. CCL17 is constitutively expressed in the thymus and, under activation, in several cell types. CCL17-mediated recruitment of Th2 cells and CLA+ CD4+ T cells plays a key role in allergic diseases such as atopic dermatitis, allergic asthma, allergic rhinitis, and allergic contact dermatitis. In addition, CCL17 has been detected in idiopathic pulmonary fibrosis. CCL17 and CCL22 secreted by dendritic cells (DCs) seem to mediate the recruitment of regulatory T cells to sites of inflammation in patients with chronic hepatitis.
