Background Information


Human CD196, also known as CCR6 (C-C chemokine receptor 6), is a member of the G protein-coupled receptor (GPCR) family that regulates immune cell migration and tissue homing. CD196 is expressed on immature dendritic cells, memory T cells, B cells, regulatory T cells (Tregs), Th17 cells, innate lymphoid cells, and subsets of natural killer (NK) cells. It plays a critical role in directing leukocytes to epithelial tissues and sites of inflammation, particularly the skin, lungs, and gastrointestinal tract, where it contributes to both immune surveillance and inflammatory responses.

CCR6 is a seven-transmembrane domain receptor composed of approximately 374 amino acids, with an extracellular N-terminus involved in ligand recognition and an intracellular C-terminal tail that mediates signaling. Its primary and highly specific ligand is CCL20 (also known as macrophage inflammatory protein-3 alpha, MIP-3α, or liver activation-regulated chemokine, LARC). Binding of CCL20 to CCR6 activates heterotrimeric Gi proteins, triggering intracellular signaling pathways including PI3K, MAPK, and calcium mobilization, which promote chemotaxis, cell survival, and immune cell activation.

The CCR6-CCL20 signaling axis plays an important role in numerous inflammatory and autoimmune diseases. Elevated CCR6 expression is associated with psoriasis, rheumatoid arthritis, inflammatory bowel disease, multiple sclerosis, asthma, and systemic lupus erythematosus, largely through the recruitment of Th17 cells and other pro-inflammatory leukocytes. In cancer, CCR6 expression has been linked to tumor progression, metastasis, and immune cell infiltration in malignancies such as colorectal, breast, pancreatic, and hepatocellular carcinoma, although its biological effects vary depending on the tumor microenvironment.

Because of its central role in immune cell trafficking, CCR6 has emerged as an attractive therapeutic target. Small-molecule antagonists, monoclonal antibodies, and inhibitors of the CCR6-CCL20 axis are under investigation for the treatment of autoimmune diseases, chronic inflammatory disorders, and cancer. Modulating CCR6 signaling may reduce pathogenic immune cell recruitment while preserving normal immune surveillance, making CD196 a promising target for future immunotherapies and precision medicine approaches.

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.
