CCR6


Also found in: Acronyms.

CCR6

A gene on chromosome 6q27 that encodes a member of the beta chemokine receptor family, which is similar to G protein-coupled receptors. CCR6 is preferentially expressed by immature dendritic cells and memory T cells, and may be important for B-lineage maturation and antigen-driven B-cell differentiation; it may regulate migration and recruitment of dentritic and T cells during inflammation. Its ligand is macrophage inflammatory protein 3 alpha (MIP-3 alpha).

TI-Treg cells express a variety of chemokine receptors, including CCR4, CCR5, CCR6, CCR7, CCR10, CXCR3, and CXCR4, and migrate efficiently in response to tumor-derived chemokines [23, 95, 96].
Analysis of the expression levels of the chemokine receptors CXCR3, CCR6, and CCR4 enables further characterization of peripheral blood Thelper-like subsets [35-37].
The majority of the extracellular flow cytometry experiments were performed directly on fresh cells, but for six donors, the T cell markers CD69, CD25, CXCR3, CCR6, CD38, HLA-DR, CD127, and PD-1 were analyzed on paired frozen samples.
Tfh and Th17 cells also differ in the ability to home to different immune microenvironments; while most Tfh cells are [CXCR5.sup.+] and migrate to the secondary lymphoid tissue B cell areas, Th17 cells, when activated, down regulate CCR7 and up regulate CCR6, migrating to the target organs where they exert their effector functions.
(47),(68),(69) The interaction between chemokines produced in the interfollicullar region of the PPs and chemokine receptors, such as between CCL19 and CCR7 and between CCL20 and CCR6, plays an important role in the transport of dendritic cells to T cell zones.
Thus, these chemokine receptors, along with CCR6, are involved in recruiting Tregs to the tumor site.
Furthermore, Langerhans cell recruitment is induced by CCR6 related chemokines [119].
