A serous demilune or Crescents of Gianuzzi is a cap in the shape of a half-moon (hence the name demilune) on some salivary glands.Serous demilunes are the serous cells at the distal end of mucous tubuloalveolar secretory unit of certain salivary glands.These demilune cells secrete the proteins that contain the enzyme lysozyme, which degrades the cell walls of bacteria. In this way, lysozyme confers antimicrobial activity to mucus.he serous demilune is an artifact from traditional methods of preparing samples. Samples are traditionally preserved and fixed in formaldehyde. When samples were preserved by quick-freezing in liquid nitrogen and then fixed with osmium tetraoxide in acetone, no demilunes are found.
