Anti-Adhesion Effects of Lactobacillus Strains on Caco-2 Cells Against Escherichia Coli and Their Application in Ameliorating the Symptoms of Dextran Sulfate Sodium-Induced Colitis in Mice

Tao Wang et al.

Summary: The study measured the adhesion abilities of four Lactobacillus strains and their anti-adhesion effects on pathogenic bacteria in Caco-2 cells, as well as their role in alleviating UC. The results showed that the tested strains had promising effects in ameliorating UC, and there was no significant correlation between the adhesion abilities of probiotics and their role in improving UC.

Species-Specific Endotoxin Stimulus Determines Toll-Like Receptor 4- and Caspase 11-Mediated Pathway Activation Characteristics

Orna Ernst et al.

Summary: The innate immune system serves as the body's first line of defense against pathogens, with Toll-like receptor 4 (TLR4) and caspase 11 mediating different signaling pathways leading to cell death and inflammation. Variations in the structure of lipopolysaccharide (LPS) from different Gram-negative bacteria may result in specific immune responses, impacting the selection of therapeutic strategies.
