Une grande partie des granulomes périapicaux est constituée de cellules du système mononucléaire phagocytaire et lymphoïde. Les caractéristiques ultrastructurales des monocytes/macrophages diffèrent selon le type d’activité des cellules (phagocytose ou sécrétion). Une corrélation intime entre les cellules de ces deux systèmes peut être supposée étant donné leurs contacts serrés. Un rôle important dans la résorption osseuse est exercé, probablement par l’intermédiaire de cytokines comme IL-1 beta et TNF.
A large portion of periapical granulomas is composed by cells of the mononuclear-phagocyte and lymphoid system. The ultrastructural features of the monocytes/macrophages differ in relationship to the state of activity of the cells (phagocytosis or secretion). A close correlation between cells of these two systems can be surmised by their tight contacts. An important role in the bone resorption is probably played by cytokines like IL-1 and TNF.
