Function of epithelial alarmins
WebMoreover, intestinal epithelial cells (IECs) express MHCI/II, Epithelial cells have indeed an immunologic function: they are thus having the possibility to induce specific antigen immune the first sensors of external damage, producing and secreting responses towards allergenic components, and these cells secrete alarmins IL-25, IL-33 and ... Their main function is the management of calcium storage and shuffling. Although they have various functions, including cell proliferation , differentiation , migration , and energy metabolism , they also act as DAMPs by interacting with their receptors (TLR2, TLR4, RAGE) after they are released from phagocytes . See more Damage-associated molecular patterns (DAMPs) are molecules within cells that are a component of the innate immune response released from damaged or dying cells due to trauma or an infection by a pathogen. … See more DAMPs vary greatly depending on the type of cell (epithelial or mesenchymal) and injured tissue, but they all share the common feature of … See more • Kaczmarek A, Vandenabeele P, Krysko DV (February 2013).
