How Do Commensal Microorganisms Interact with Host Tissues?
The interaction between commensal microorganisms and host tissues is highly complex and involves both direct and indirect mechanisms. Direct interactions include the colonization of epithelial surfaces and the modulation of immune responses. Indirectly, commensal microorganisms produce metabolites and antimicrobial peptides that influence the behavior of host cells. Histologically, these interactions can be observed as changes in tissue structure, such as the thickening of the mucus layer in the gastrointestinal tract.
