Background Information


CD196, also known as CCR6, is a chemokine receptor that regulates immune-cell migration, positioning, and inflammatory responses. It is expressed on several immune-cell populations, including memory and activated T cells, Th17 cells, regulatory T cells (Tregs), and subsets of B cells and dendritic cells. Through recognition of chemokines, CCR6 helps direct these cells to mucosal tissues and sites of inflammation, where they participate in immune surveillance, pathogen defense, and the regulation of immune responses.



CCR6 is a seven-transmembrane G protein-coupled receptor (GPCR) belonging to the class A chemokine receptor family. Its extracellular regions recognize chemokine ligands, while its intracellular domains couple to G proteins and activate signaling pathways that regulate chemotaxis, cell adhesion, and migration. The principal ligand of CCR6 is CCL20, also known as macrophage inflammatory protein-3 alpha (MIP-3α) or liver and activation-regulated chemokine (LARC). CCL20 is produced by epithelial cells and various immune and stromal cells, particularly during inflammation. The CCL20–CCR6 axis is especially important for recruiting CCR6-expressing cells to mucosal surfaces, including the intestinal tract and skin.



CCR6 contributes to immune defense at barrier tissues, but dysregulation of its signaling can promote chronic inflammation and autoimmune disease. The CCL20–CCR6 axis has been implicated in psoriasis, rheumatoid arthritis, inflammatory bowel disease, and multiple sclerosis, partly through the recruitment and positioning of Th17 cells and other inflammatory leukocytes. Its effects depend on the tissue and immune-cell population involved; CCR6 expression on regulatory T cells may also support immune suppression and tissue homeostasis. In cancer, this pathway can influence tumor-associated inflammation and immune-cell infiltration, with effects that vary by tumor type and microenvironment.



Therapeutically, CCR6 and CCL20 are being investigated as potential targets for controlling inflammatory and autoimmune diseases. Blocking this pathway may reduce the recruitment of pathogenic immune cells into affected tissues. Conversely, manipulating CCR6-mediated trafficking could help direct beneficial immune cells to specific tissues or tumors. Because CCR6 is expressed by both inflammatory and regulatory populations, therapeutic strategies must account for its context-dependent effects on immune protection, inflammation, and tumor immunity.

Frequently Asked Questions


How do I determine the optimal antibody concentration/titer for my experiment?
We recommend titrating each new antibody lot on your own cell type and instrument, since optimal concentration depends on cell density, target expression level, and cytometer sensitivity. Suggested starting dilutions or test sizes (e.g., µg or µl per 10^6 cells) are provided on the product page as a starting reference point, not a fixed requirement.

Can these antibodies be used for intracellular or intranuclear staining, or only surface staining?
Intended use (surface, intracellular, or both) is specified per product, indicated under Application. The appropriate Related Protocol is linked for each product. If you need to detect both surface and intracellular markers in the same panel, confirm each antibody's compatibility with your fixation/permeabilization protocol before combining them.

What controls should I use alongside these antibodies?
Matched isotype controls (same host species, isotype, and conjugate) are available for most clones to help distinguish specific binding from background/non-specific staining and are linked on each product page. Unstained, single-color compensation, and fluorescence-minus-one (FMO) controls are also recommended, especially for multicolor panel design.

Can I combine InnoCyto Flow Cytometry antibodies into a multicolor panel?
Yes — antibodies across our catalog are designed to be panel-compatible, and conjugate options are offered specifically to support multiplexing. When building a panel, pair bright fluorophores with low-expression targets, avoid excessive spectral overlap, and confirm compensation is set up correctly for your specific fluorochrome combination. Use our Panel Builder to simplify the process.
