Chemokine (C-C motif) ligand 19(CCL19) is aproteinthat in humans is encoded by theCCL19gene.[5][6]

This gene is one of several CC cytokine genes clustered on the p-arm of chromosome 9. Cytokines are a family of secreted proteins involved in immunoregulatory and inflammatory processes. The CC cytokines are proteins characterized by two adjacent cysteines. The cytokine encoded by this gene may play a role in normal lymphocyte recirculation and homing. It also plays an important role in trafficking of T cells in thymus, and in T cell and B cell migration to secondary lymphoid organs. It specifically binds to chemokine receptorCCR7.[6]

Chemokine (C-C motif) ligand 19 (CCL19) is a smallcytokinebelonging to the CCchemokinefamily that is also known asEBI1 ligand chemokine(ELC) andmacrophage inflammatory protein-3-beta(MIP-3-beta). CCL19 is expressed abundantly inthymusandlymph nodes,with moderate levels intracheaandcolonand low levels in stomach,small intestine,lung,kidneyandspleen.[7]The gene for CCL19 is located on humanchromosome 9.[8]This chemokine elicits its effects on its target cells by binding to the chemokine receptorchemokine receptorCCR7.[7]It attracts certain cells of theimmune system,includingdendritic cellsand antigen-engagedB cells,[9][10]CCR7+central-memory T-Cells.[11]
