Experimental evolution of resistance to an antimicrobial peptide. Paneth cells are sometimes seen in the colorectal tubules, for example in the ce colonic mucosa of elderly subjects [ 717 ], in patients with ulcerative colitis [ 18 ] and colonic epithelial neoplasia [ 11920 ], although the reasons pwneth Paneth cells appear in the large bowel is still unknown.

pnaeth The carcinogenesis of colorectal cancer has been accepted by a model for a cascade of genetic alterations, named the adenoma-carcinoma sequence. This structure allows defensins to insert into membranes, where they interact with one another to form pores that disrupt membrane function, leading to cell lysis.
