CD199, also known as CCR9, is a member of the G protein-coupled receptor (GPCR) family and functions as a chemokine receptor. It is a ~42 kDa seven-transmembrane protein primarily involved in T cell development in the thymus and gut-associated immune responses. CCR9 is expressed on T lymphocytes and is upregulated in response to retinoic acid, which is produced by dendritic cells, facilitating the migration of T cells to gut-associated tissues. Its specific ligand is CCL25 (TECK), and the interaction between CCR9 and CCL25 plays a crucial role in the recruitment and maturation of thymocytes. Additionally, CCR9 is differentially expressed in T lymphocytes of the small intestine and colon, suggesting its involvement in specialized immune responses within the gastrointestinal tract.
Flow cytometric analysis of C57BL/6 mouse thymocytes labelling Mouse CD199 Antibody at 1/200 dilution (1 μg) / (Right panel) compared with a Rat IgG2a, κ Isotype Control / (Left panel). Goat Anti-Rat IgG Alexa Fluor® 488 was used as the secondary antibody. Then cells were stained with CD4 - Brilliant Violet 421™ Antibody separately.
