This gene encodes a member of the beta chemokine receptor family, which is predicted to be a seven transmembrane protein similar to G protein-coupled receptors. The gene is preferentially expressed by immature dendritic cells and memory T cells. The ligand of this receptor is macrophage inflammatory protein 3 alpha (MIP-3 alpha). This receptor has been shown to be important for B-lineage maturation and antigen-driven B-cell differentiation, and it may regulate the migration and recruitment of dentritic and T cells during inflammatory and immunological responses. Alternatively spliced transcript variants that encode the same protein have been described for this gene. [provided by RefSeq, Jul 2008]
Forensic Context
A study in rats demonstrated that polytrauma (osteotomy, blunt chest trauma, and burn) significantly upregulated local mRNA expression of the CCR6 at the fracture site 24 hours post-trauma compared to osteotomy alone, indicating an altered early local immune response [Mangum et al. DOI:10.1186/s13018-019-1082-4]. This dysregulated inflammatory state was associated with significantly impaired bone healing, as evidenced by a reduced bone volume fraction at five weeks.
