Bacterial Translocation and Host Immune Activation in Chronic Hepatitis C Infection

Open Forum Infectious Diseases
Mi Sun MoonTheo Heller

Abstract

Hepatitis C virus (HCV) infects 71 million individuals, and barriers to treatment remain. Bacterial translocation is a complication of chronic HCV infection, and this study evaluated circulating microbial components including lipopolysaccharide, peptidoglycan, and β-D-glucan in addition to their pattern recognition receptors and degree of hepatic macrophage uptake. The findings suggest that regulation of serum peptidoglycan and β-D-glucan differs from that of lipopolysaccharide. Additionally, macrophage activation in the liver may be better reflected by the degree of macrophage uptake than by circulating levels of microbial markers. These findings allow for a greater understanding of bacterial translocation and host immune activation during HCV infection.

Bacterial Cell Wall Structure

Bacterial cell walls are made of peptidoglycan (also called murein), which is made from polysaccharide chains cross-linked by unusual peptides containing D-amino acids. Here is the latest research on bacterial cell wall structures.
