Dysbiosis and Neutrophilic Inflammation

Improper regulation of MMP-9 activity associated with numerous disorders such as COPD, lung cancer, asthma, emphysema, cystic fibrosis, fibrotic lung diseases such as Idiopathic pulmonary fibrosis (IPB) and COVID-19.

Increased MMP-9 Activity
Increased Collagen Breakdown
Increased Ac-PGP Activity
Increased CXCR2 Activity
Increased Neutrophilic Infiltration
Inflammation of the Lungs

resB® decreases MMP-9 levels in Human lung epithelial cells

  • resB®  was found to reverse MMP-9 cascade in in vitro dysbiosis model of lung epithelial cells.
  • resB®  was found to reduce neutrophils, cell count and MPO activity in in vivo model of dysbiosis.
  • resB®  downregulates MMP-9 gene expression in mouse lung tissue.
Illustration showing the effect of dysbiosis and resB on human epithelial cells with reduced MMP-9 levels and decreased neutrophilic inflammation.

resB® downregulates the mRNA expression and levels of MMP-9 protein in E.coli.

Bar graph comparing MMP-9 mRNA levels in E.coli versus E.coli treated with resB blend showing downregulation of MMP-9 expression.

resB® prevents lung tissue damage in in-vivomodel of dysbiosis (Mice)

Histology images of mouse lung tissue comparing control vs. LPS-induced lung inflammation and dysbiosis, with resB® treatment showing reduced alveolar damage, improved lung architecture, and lower mean linear intercept values in an in-vivo lung injury model.

resB® reduces BAL Neutrophils, Cell Count, MPO, CRP, MMP-9 mRNA as well as Protein Levels, in In-vivo model of Lung Dysbiosis (Mice).

Graphs showing the effect of resB treatment in a mouse model of lung dysbiosis, including reductions in BAL cell count, neutrophils, MPO levels, CRP levels, and MMP-9 protein and mRNA expression compared to LPS group.
