SCIENCE

​ClostraBio offers versatile solutions for delivery of bacterial metabolites.
PROBIOTIC SUPPLEMENT​
CLB101™ is a butyrate-producing probiotic found to be in decreased abundance in infants with food allergy 

THERAPEUTIC ASSET​
CLB-004 treats the underlying condition in non-communicable chronic diseases of the gut, by  modulating barrier function and immune response
Non-communicable chronic diseases are associated with impaired barrier function
Due to an altered intestinal microbiome

Decreased dietary fiber

Decreased bacterial diversity

​Decreased short chain fatty acid (SCFA) production​

​Impaired intestinal ​barrier function​
Disruption of tight junctions & mucus film covering the epithelial layer causes increased permeability of the intestinal epithelium & increased uptake of luminal or food antigens, ultimately leading to chronic inflammation.

Modern lifestyle factors, including diets low in dietary fiber, results in a loss of gut microbial diversity linked to decreased levels of key bacterial metabolites and impaired intestinal barrier function​.

Hypothesis: directly deliver bacterial metabolites
Utilize butyrate to correct impaired intestinal barrier function
Picture
​In preclinical models, butyrate-producing bacteria in the Clostridia class protect against intestinal inflammation
​Butyrate induces IL-22, a barrier protective cytokine​
Butyrate supports:​
  • Beneficial bacterial community and a bacteria-induced barrier protective response​
  • Epithelial energy metabolism​
  • Immunomodulation through differentiation of Tregs

Probiotic solution​
Support the gut microbiome by supplementing with CLB101™, a butyrate-producing commensal bacterial strain
