Chemokine CCL21

• 

  Subject Areas on Research

  • A chemokine expressed in lymphoid high endothelial venules promotes the adhesion and chemotaxis of naive T lymphocytes. 
  • A high endothelial cell-derived chemokine induces rapid, efficient, and subset-selective arrest of rolling T lymphocytes on a reconstituted endothelial substrate. 
  • An essential role for Prox1 in the induction of the lymphatic endothelial cell phenotype. 
  • CCL-21 conditioned regulatory T cells induce allotolerance through enhanced homing to lymphoid tissue. 
  • Cutting edge: hierarchy of chemokine receptor and TCR signals regulating T cell migration and proliferation. 
  • Dendritic Cells Interpret Haptotactic Chemokine Gradients in a Manner Governed by Signal-to-Noise Ratio and Dependent on GRK6. 
  • Effector T Cell Egress via Afferent Lymph Modulates Local Tissue Inflammation. 
  • Enhanced allergen-induced airway inflammation in paucity of lymph node T cell (plt) mutant mice. 
  • Gene duplications at the chemokine locus on mouse chromosome 4: multiple strain-specific haplotypes and the deletion of secondary lymphoid-organ chemokine and EBI-1 ligand chemokine genes in the plt mutation. 
  • Mice lacking expression of secondary lymphoid organ chemokine have defects in lymphocyte homing and dendritic cell localization. 
  • Mice lacking expression of the chemokines CCL21-ser and CCL19 (plt mice) demonstrate delayed but enhanced T cell immune responses. 
  • Oncostatin M enhances CCL21 expression by microvascular endothelial cells and increases the efficiency of dendritic cell trafficking to lymph nodes. 
  • Permanent survival of fully MHC-mismatched islet allografts by targeting a single chemokine receptor pathway. 
  • Plasmacytoid dendritic cells in inflamed muscle of patients with juvenile dermatomyositis. 
  • S1P-Dependent trafficking of intracellular yersinia pestis through lymph nodes establishes Buboes and systemic infection. 
  • Secondary lymphoid-tissue chemokine (SLC) stimulates integrin alpha 4 beta 7-mediated adhesion of lymphocytes to mucosal addressin cell adhesion molecule-1 (MAdCAM-1) under flow. 
  • The CC chemokine thymus-derived chemotactic agent 4 (TCA-4, secondary lymphoid tissue chemokine, 6Ckine, exodus-2) triggers lymphocyte function-associated antigen 1-mediated arrest of rolling T lymphocytes in peripheral lymph node high endothelial venules.
