We describe a protein with the hallmarks of a chemokine, designated CXCL16, that is made by dendritic cells (DCs) in lymphoid organ T cell zones and by cells in the splenic red pulp. CXCL16 contains a transmembrane domain and both membrane-bound and soluble forms are produced. Naïve CD8 T cells, natural killer T cells and a subset of memory CD4 T cells bind CXCL16, and activated T cells migrated chemotactically to the soluble chemokine. By expression cloning, Bonzo (also known as STRL33 and… 

The Membrane-Bound Chemokine CXCL16 Expressed on Follicle-Associated Epithelium and M Cells Mediates Lympho-Epithelial Interaction in GALT1

The data suggest that CXCL16 expressed on the follicle-associated epithelium plays an important role in the recruitment and retention of activated T cells in the SED and should, at least partially, be responsible for lymphocyte compartmentalization in GALT.

Expression Cloning of the STRL33/BONZO/TYMSTR Ligand Reveals Elements of CC, CXC, and CX3C Chemokines

The combination of unique structural features of both Bonzo and CXCL16 suggest that this interaction may represent a new class of ligands for this receptor family, and this chemokine might play a unique dual role of attracting activated lymphocyte subsets during inflammation as well as facilitating immune responses via cell-cell contact.

A transmembrane chemokine, CXC chemokine ligand 16, expressed by lymph node fibroblastic reticular cells has the potential to regulate T cell migration and adhesion.

It is shown that a mouse lymph node (LN)-derived FRC cell line, BLS4, expresses a transmembrane chemokine, CXC Chemokine ligand (CXCL) 16, in response to tumor necrosis factor alpha (TNFalpha) and IFNgamma, suggesting that CXCL16 is an important mediator of lymphocyte-stromal interaction within lymphoid tissues.

A Disintegrin and Metalloproteinase 10-Mediated Cleavage and Shedding Regulates the Cell Surface Expression of CXC Chemokine Ligand 16

The identification of ADAM10 as a major protease responsible for the conversion of CXCL16 from a membrane-bound scavenger receptor to a soluble chemoattractant will provide new information for understanding the physiological function of this molecule.

Bonzo/CXCR6 expression defines type 1-polarized T-cell subsets with extralymphoid tissue homing potential.

It is shown that newly identified chemokine receptor Bonzo/CXCR6 is expressed by subsets of Th1 or T-cytotoxic 1 (Tc1) cells, but not by Th2 or Tc2 cells, establishing Bonzo as a differential marker of polarized type 1 T cells in vitro and in vivo.

CD1d-Restricted CXCR6 in Homeostasis and Activation of Critical Role for the Chemokine Receptor

Cytokine production by liver and spleen NKT cells was impaired in CXCR6 / CXCL16 mice following in vivo stimulation with (cid:3) -galactosylceramide, implicating a novel role for CX CR6 in NKT cell activation.

Transmembrane chemokines act as receptors in a novel mechanism termed inverse signaling

The transmembrane chemokines CX3CL1/fractalkine and CXCL16 are widely expressed in different types of tumors, often without an appropriate expression of their classical receptors. We observed that

Chemokines in the systemic organization of immunity

The role of chemokines and their receptors in the spatial organization of the immune system is summarized and the implications for immune function are considered.



A new class of membrane-bound chemokine with a CX3C motif

The structure, biochemical features, tissue distribution and chromosomal localization of CX3C chemokine all indicate that it represents a unique class of chemokines that may constitute part of the molecular control of leukocyte traffic at the endothelium.

STRL33, A Novel Chemokine Receptor–like Protein, Functions as a Fusion Cofactor for Both Macrophage-tropic and T Cell Line–tropic HIV-1

STRL33, in contrast with CXCR4 or CCR5, was able to function as a cofactor for fusion mediated by Envs from both T cell line–tropic and macrophage-tropic HIV-1 strains, and may play a role in the establishment and/or progression of HIV- 1 infection.

Fractalkine, a CX3C chemokine, is expressed by dendritic cells and is up‐regulated upon dendritic cell maturation

It is shown that FK is associated with dendritic cells (DC) in epidermis and lymphoid organs and may play a role in the ability of T cells and mature DC to form conjugates and engage in cell‐cell communication.

Human chemokines: an update.

Of considerable interest is the recent discovery that some chemokines function as HIV-suppressive factors by interacting with chemokine receptors which, together with CD4, were recognized as the binding sites for HIV-1.

Epstein-Barr Virus–induced Molecule 1 Ligand Chemokine Is Expressed by Dendritic Cells in Lymphoid Tissues and Strongly Attracts Naive T Cells and Activated B Cells

A central role for ELC is suggested in promoting encounters between recirculating T cells and dendritic cells and in the migration of activated B cells into the T zone of secondary lymphoid tissues.

Neurotactin, a membrane-anchored chemokine upregulated in brain inflammation

It is proposed that neurotactin represents a new δ-chemokine family and that it may play a role in brain inflammation processes.

Chemokines and cell migration in secondary lymphoid organs.

Current understanding of the roles played by chemokines in the functional biology of secondary lymphoid organs will be reviewed and a central role for the chemokine family of molecules has been uncovered.

Fractalkine and macrophage‐derived chemokine: T cell‐attracting chemokines expressed in T cell area dendritic cells

While fractalkine and MDC belong to different families of chemokines, both may be involved in recruitment of T cells for interaction with mature DC in the immune response.

Chemokine Up-regulation and activated T cell attraction by maturing dendritic cells.

These studies identified chemokine up-regulation as part of the Langerhans' cell maturation program to immunogenic T cell-zone DC as a mechanism used by maturing DCs to promote encounters with antigen-specific T cells.
