Conversion of progenitors and differentiated cells into goblet cells by conditional deletion: 15959515 [59] REG4: Marker for enteroendocrine cells: 26287467 [60] SOX9: Required for paneth cell differentiation: 17698607; [61] 17681175 [62] SPDEF: PDEF: Regulates terminal differentiation of goblet cells and Paneth cells: 19786015; [63] 19549527 ...
Intestinal stem cells were first identified as such in the 1970s. Cheng and Leblond used autoradiography of phagosomes to track the fate of cells at the base of the crypts, and determined that slender cells interspersed among Paneth cells at the crypt base could give rise to all of the other cell types that constituted the intestinal epithelium ...
Paneth cells are found throughout the small intestine and the appendix at the base of the intestinal glands. [2] There is an increase in Paneth cell numbers towards the end of the small intestine. [3] Like the other epithelial cell lineages in the small intestine, Paneth cells originate at the stem cell region near the bottom of the gland. [4]
Subsets of sensory intestinal epithelial cells synapse with nerves, [9] and are known as neuropod cells. [10] Paneth cells produce antimicrobial peptides such as human alpha-defensin. [11] [12] Microfold cells (commonly referred to as M cells) sample antigens from the lumen and deliver them to the lymphoid tissue associated with the mucosa (MALT).
The nuclei of the cells (located at the outer edges of the cells lining the walls of the crypts) are stained blue-gray with haematoxylin. As seen in panels C and D, crypts are about 75 to about 110 cells long. The average crypt circumference is 23 cells. [8] From the images, an average is shown to be about 1,725 to 2530 cells per colonic crypt.
NOD2 is a receptor produced by Paneth cells to sense bacteria, and mutations to NOD2 can inhibit the antimicrobial activity of Paneth cells. ATG16L1, IRGM , and LRRK2 are proteins involved in selective autophagy , the mechanism by which Paneth cells secrete α-defensins, and mutations to these genes also impair the antimicrobial activity of ...
Intestinal stem cell aging has been studied in Drosophila as a model for understanding the biology of stem cell/niche aging. [4] Using knockdown mutants defective in various genes that function in the DNA damage response in enterocytes, it was shown that deficiency in the DNA damage response accelerates intestinal stem cell aging, thus ...
[5] [6] DEFA5 is expressed in the Paneth cells of the ileum. [7] Defensins are a family of microbicidal and cytotoxic peptides (antimicrobial peptides; AMP) that are involved in host defense, and help to maintain homeostasis of intestinal microbiota. DEFA5 is the main AMP that controls the enteric microbiota composition by selective killing of ...
