Antimicrobial Peptide YD
Antimicrobial Peptide YD is an Antimicrobial peptide. Antimicrobial Peptide YD attenuates the TLR4/MYD88/NF-κB signaling pathway, inhibits ROS production, upregulates the expression of antioxidant enzymes, reduces the levels of inflammation-related factors, and prevents the downregulation of E-cadherin and upregulation of Vimentin. Antimicrobial Peptide YD exhibits activity against Gram-positive bacteria, Gram-negative bacteria, and multidrug-resistant bacteria. Antimicrobial Peptide YD possesses anti-inflammatory, antifibrotic, and antioxidant effects. Antimicrobial Peptide YD can be used in pulmonary fibrosis research.

Biological Activity
|
TLR4 |
Antimicrobial Peptide YD (50-100 μM) exhibits potent anti-inflammatory activity in lung epithelial A549 cells, and inhibits inflammation induced by the cytokine (TNFα) and oxidative stress (H2O2)[1].
Antimicrobial Peptide YD (25-50 μM; 24 h) inhibits the TGF-β1-induced fibrotic response in mouse fibroblast cell line NIH-3T3, and reduces the expression of key fibrotic proteins (α-SMA, MMP2, Col1, FN) and their corresponding mRNAs[1].
Antimicrobial Peptide YD inhibits TGF-β1-induced fibrotic responses and epithelial-mesenchymal transition in pulmonary epithelial A549 cells, reduces the expression of fibrosis markers, and maintains the epithelial cell phenotype[1].
Antimicrobial Peptide YD exhibits poor serum stability in mouse serum, with a half-life of 21.31 min[1].
Antimicrobial Peptide YD (24 h) inhibits TGF-β1-induced type I collagen expression in mouse fibroblast cell line NIH-3T3[1].
