Human β-defensin-1
Based on 1 Customer Validation
Human β-defensin-1 (HβD-1) is an antimicrobial peptide and immunomodulator that induces angiogenin secretion from fibroblasts through EGFR, JNK, NF-κB, Src, and p38 signaling pathways, and binds CCR6 to activate G protein signaling, while also inducing ER stress, apoptosis, cell cycle arrest, and autophagy. Human β-defensin-1 can be used in research on hepatocellular carcinoma, influenza A virus infection, male infertility, colon cancer, and bacterial infections caused by antibiotic-resistant strains.

제품 설명
IC50 & Target
IC50: skin-antimicrobial peptide (SAP)[1]
In Vitro
Human β-defensin-1 (HβD-1) (10-20 µg/mL; 3-24 h) enhances angiogenin secretion from normal human dermal fibroblasts in a dose-and time-dependent manner[1].
Human β-defensin-1 (20 μg/mL; 30-180 min) induces phosphorylation of EGFR in normal human dermal fibroblasts[1].
Human β-defensin-1 (20 μg/mL; 6 h) enhances angiopoietin production in normal human dermal fibroblasts through the EGFR pathway[1].
Human β-defensin-1 (20 μg/mL; 30-120 min) induces Src phosphorylation in normal human dermal fibroblasts[1].
Human β-defensin-1 (20 µg/mL) mediates angiogenin secretion in normal human dermal fibroblasts via the Src signaling pathway[1].
Human β-defensin-1 (20 µg/mL) mediates angiogenin secretion by normal human dermal fibroblasts through the NF-κB signaling pathway[1].
Human β-defensin-1 (20 µg/mL; 5-60 min) induces phosphorylation of p38, JNK, and ERK1/2 in normal human dermal fibroblasts[1].
Human β-defensin-1 (20 µg/mL; 6 h)-mediated angiogenin production in normal human dermal fibroblasts requires activation of the p38 and JNK pathways, but not the ERK pathway[1].
Human β-defensin-1 (20 µg/mL; 60 min) induces nuclear translocation of NF-κB in normal human dermal fibroblasts[1].
Human β-defensin-1 (500 ng/mL; 1-3 h) co-incubated with DGC-treated human sperm significantly maintained sperm motility for up to 2 hr and sperm viability for up to 3 hr[3].
Human β-defensin-1 (MOI of 1; 24 h) significantly restricts IAV replication in human HBEpCs, reducing matrix gene copy numbers by 99%[2].
Human β-defensin-1 overexpression (MOI 0.5-1.0; 24 h) upregulated STAT3 protein expression and its phosphorylation at Tyr705 in HBEpCs, both in uninfected and A (H1N1)-infected cells[2].

Cell Line:Normal human dermal fibroblasts
-
Concentration:10, 20 µg/mL
-
Incubation Time:3, 6, 12, 24 h
-
Result:Enhanced the secretion of ANG dose- and time-dependently.
Observed a five-fold increase in ANG levels at 6 h poststimulation.
Observed a 10-fold increase in ANG levels at 12 h.
Significantly induced the production of ANG as early as 3 h.
Had little effect on the mRNA expression of ANG.

-
Concentration:20 µg/mL
-
Incubation Time:3, 6, 24 h
-
Result:Significantly increased the secretion of ANG by ex vivo-cultured fibroblasts.
Observed the hBD-1-mediated stimulatory effect only at 6 h poststimulation.
-
Cell Line:Normal human dermal fibroblasts
-
Concentration:20 μg/mL
-
Incubation Time:30, 60, 120, 180 min
-
Result:Increased the phosphorylation of EGFR between 30 and 120 min after stimulation.
-
Cell Line:Normal human dermal fibroblasts
-
Concentration:20 μg/mL
-
Incubation Time:6 h
-
Result:Suppressed ANG secretion induced by hBD-1 with pretreatment with AG1478, confirming that hBD-1 enhanced ANG production via the EGFR pathway.
-
Cell Line:Normal human dermal fibroblasts
-
Concentration:20 μg/mL
-
Incubation Time:30, 120 min
-
Result:Induced Src phosphorylation.
First observed activation at 30 min poststimulation.
Peaked at 120 min.
-
Cell Line:Normal human dermal fibroblasts
-
Concentration:20 µg/mL
-
Incubation Time:5, 15, 30, 60 min
-
Result:Increased the phosphorylation of p38 at 5 min, and this phosphorylation was still remarkable at 60 min after stimulation.
Enhanced JNK and ERK1/2 phosphorylation, which peaked at 5 min, before decreasing.
-
Cell Line:Normal human dermal fibroblasts
-
Concentration:20 µg/mL
-
Incubation Time:6 h
-
Result:Decreased hBD-1-mediated ANG production markedly with SB203580 (p38 inhibitor) and JNK inhibitor II, while U0126 (ERK inhibitor) had no effect on ANG secretion.
-
Cell Line:Normal human dermal fibroblasts
-
Concentration:20 µg/mL
-
Incubation Time:60 min
-
Result:Increased the levels of NF-κB in the nucleus significantly at 60 min poststimulation.
