  2. Paneth cell - Wikipedia

    en.wikipedia.org/wiki/Paneth_cell

    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]

  3. Intestinal gland - Wikipedia

    en.wikipedia.org/wiki/Intestinal_gland

    During each mitosis, one of the two daughter cells remains in the crypt as a stem cell, while the other differentiates and migrates up the side of the crypt and eventually into the villus. These stem cells can differentiate into either an absorptive (enterocytes) or secretory (Goblet cells, Paneth cells, enteroendocrine cells) lineages. [3]

  4. Gastrointestinal wall - Wikipedia

    en.wikipedia.org/wiki/Gastrointestinal_wall

    Paneth cell: Intestinal glands: Secretion of the bactericidal enzyme lysozyme; phagocytosis G cells: Intestinal glands of duodenum: Secretion of the hormone intestinal gastrin: I cells: Intestinal glands of duodenum: Secretion of the hormone cholecystokinin, which stimulates release of pancreatic juices and bile K cells: Intestinal glands

  5. Intestinal epithelium - Wikipedia

    en.wikipedia.org/wiki/Intestinal_epithelium

    Goblet cells secrete the mucus layer which protects the epithelium from the luminal contents. Enteroendocrine cells secrete various gastrointestinal hormones including secretin, pancreozymin, enteroglucagon among others. Subsets of sensory intestinal epithelial cells synapse with nerves, [9] and are known as neuropod cells. [10] Paneth cells ...

  6. Lysozyme - Wikipedia

    en.wikipedia.org/wiki/Lysozyme

    Due to the unique function of lysozyme in which it can digest the cell wall and causes osmotic shock (burst the cell by suddenly changing solute concentration around the cell and thus the osmotic pressure), lysozyme is commonly used in lab setting to release proteins from bacterium periplasm while the inner membrane remains sealed as vesicles ...

  7. Intestinal mucosal barrier - Wikipedia

    en.wikipedia.org/wiki/Intestinal_mucosal_barrier

    The mucus prevents large particles from contacting the epithelial cell layer while allowing small molecules to pass. The mucus also facilitates passage of the luminal contents along the length of the intestines, protects the epithelial cells from digestive enzymes, and prevents the direct contact of microorganisms with the epithelial layer.

    There are several things I wish I'd known before I went on my first safari in South Africa.. I didn't expect to experience a wide range of weather conditions in the winter months.

  9. Gut-associated lymphoid tissue - Wikipedia

    en.wikipedia.org/wiki/Gut-associated_lymphoid_tissue

    [2] [6] Although in these crypts conventional enterocytes are the dominant type of cells, Paneth cells can also be found. These are located at the bottom of the crypts and release a number of antibacterial substances, among them lysozyme, and are thought to be involved in the control of infections. [citation needed]
