The intestinal epithelium produces a variety of antimicrobial peptides that play a crucial role in establishing the balance of commensal organisms versus pathogens constituting the healthy host microbiota. Studies have found that, in Crohn's disease, individuals have dysbiosis, a condition in which there is disruption of the normal composition of the host microbiota. It is, therefore, not surprising that several cases of Crohn's disease have been linked to: O Reduced recruitment of neutrophils to the intestinal mucosa O Increased IL-10 secretion by intestinal macrophages O Reduced production of IL-1-3 in response to microbial antigens O Defects in production of antimicrobial peptides in Paneth cells O Reduced number of Th17 cells in the lamina propria

Question
The intestinal epithelium produces a variety of antimicrobial peptides that play a crucial role in establishing the balance of commensal organisms versus
pathogens constituting the healthy host microbiota. Studies have found that, in Crohn's disease, individuals have dysbiosis, a condition in which there is
disruption of the normal composition of the host microbiota. It is, therefore, not surprising that several cases of Crohn's disease have been linked to:
Reduced recruitment of neutrophils to the intestinal mucosa
O Increased IL-10 secretion by intestinal macrophages
O Reduced production of IL-1-3 in response to microbial antigens
O Defects in production of antimicrobial peptides in Paneth cells
O Reduced number of Th17 cells in the lamina propria
