MUC5AC and infection: Moreover, the introduction of mucin-producing cells (LS174T) allows to study the mucin binding capacity (e.g., Limosilactobacillus reuteri) and the glycan degradation (e.g., Ruminococcus gnavus) of commensal species and their effect on preventing pathogens infections, such as enteropathogenic E. coli (EPEC).
