<prompt> Paneth cells containZincCopperMolybdneumSelenium  <response>: Paneth cells are zinc-containing cells widely distributed in Lieberkuhns crypts of small intestine in many species, but their function has remained obscure. Our previous study showed that a single intravenous injection of diphenylthiocarbazone dithizone, a zinc chelator, forms zinc-dithizonate complexes in the cytoplasm of Paneth cells to ensure rapid and selective killing of the cells.
