靶點詳情

功能：

Exhibits antimicrobial activity against Gram-positive bacteria S.aureus and S.pyogenes, Gram-negative bacteria P.aeruginosa and E.coli and the yeast C.albicans. Kills multiresistant S.aureus and vancomycin-resistant E.faecium. No significant hemolytic activity was observed.
基因功能參考文獻：
1. this study shows that hBD3 amplifies the response to bacterial DNA in both mouse and human immune cells in a TLR9-dependent manner PMID: 28102569
2. the role of DEFB103 gene copy number variation (CNV) in ankylosing spondylitis (AS) susceptibility, was investigated. PMID: 26224324
3. It may be concluded hepatitis B virus up-regulates HBD-3 and A3G expression in vivo and in vitro in placental trophoblast and lack of this up-regulation is possibly associated with intrauterine transmission of hepatitis B. PMID: 25196417
4. The encoded peptide displays antimicrobial activity against S. aureus and E. faecium. PMID: 11085990
5. these observations suggest that there may be an interracial difference in DEFB4/103A copy numbers between admixed populations and a relationship between DEFB1 single nucleotide polymorphisms and DEFB4/103A copy number variation PMID: 23194186
6. Human beta-defensin 3 peptide is increased and redistributed in Crohn's ileitis PMID: 23511030
7. study demonstrates that HBD2 and 3 activate plasmacytoid dendritic cells by enhancing the intracellular uptake of CpG and self DNA and promote DNA-induced IFN-alpha production in a TLR9-dependent manner PMID: 23776172
8. Mapping of key residues in the interaction between human Beta-defensin 3 and CXCR4 reveals key defensin motifs involved in protein binding. PMID: 23659571
9. These results suggest an important role for hBD3 in inducing dendritic cell activation, migration, and polarization. PMID: 22951718
10. Using a large, unique cohort of pediatric CA-SAB, this study found no significant association between DEFB1 genetic variation or DEFB4/DEFB103 gene copy number and susceptibility for Staphylococcus aureus bacteremia PMID: 22384213
11. Human beta-defensin 3 exhibits further functions than antimicrobial peptide activity in cultured bone cells, including stimulation of proliferation and differentiation. PMID: 21520074
12. Data show that high-glucose conditions inhibited the BD3 expression of epidermal keratinocytes. PMID: 21442129
13. hBD-1 might function as a tumor suppressor gene in oral squamous cell carcinoma, while hBD-2 and -3 might be protooncogenes. PMID: 21280982
14. extraplacental membranes can react differentialy to the arrival of E. coli, secreting HBD2 and HBD3 mainly in the choriodecidua region. PMID: 21122132
15. PPARgamma regulates the 1,25D-induced hBD-3 and cathelicidin expression in keratinocytes through the regulation of AP-1 and p38 activity. PMID: 20970965
16. hBD3 represents a novel NF-kappaB-regulated mediator of CCR7 expression and anti-apoptotic pathways. PMID: 21071608
17. Inducibility of HBD3 influences the severity of Gram-positive skin infection in humans in vivo. PMID: 20404083
18. Data show that beta-defensin cluster (DEFB4, DEFB103 and DEFB104) varied between 2 and 9 copies per genome, and high copy numbers (>4) were underrepresented among patients, suggesting that increased copy numbers could protect from CD. PMID: 20483368
19. Human pulmonary cells produce hBD-3 upon L. pneumophila infection via a TLR-JNK-AP-1-dependent pathway which may contribute to an efficient innate immune defense. PMID: 20615218
