BD14 expression by tumor-infiltrating host cells results in chemoattraction of CCR6-positive B220-positive lymphocytes, which in turn initiates a proangiogenic pathway leading to enhanced angiogenesis and organized tumor tissue development.

Murine beta-defensin-14, like ultraviolet radiation (UVR), can shift surface marker expression of CD4+CD25- T cells toward a regulatory (Treg) phenotype but does not appear to play a major role in UVR-induced immunosuppression.

both hBD3 and mBD14 were chemotactic for freshly isolated mouse resident peritoneal cells. Thus, mBD14, based on structural and functional similarities, appears to be an orthologue of hBD3.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
