General Aspects of Gingival Epithelium Biology First, it was thought to provide only a physical barrier to infection and the underlying gingival attachment Epithelial cells play an active role in innate host defense by responding to bacteria in signaling further host reactions, and in integrating innate and acquired immune responses. For example, by increased proliferation, alteration of cell-signaling events, changes in differentiation and cell death, and ultimately, alteration of tissue homeostasis. 12 June 2008 Year 3 Block Head & Neck 14
Cell type of the gingival epithelium Keratinocytes Non keratinocytes cell • Melanocytes, these cells produce melanin, which is a pigment found in the skin, eyes, hair, and gingiva • Langerhans, Langerhans cells have an important role in the immune reaction as antigen-presenting cells for lymphocytes • Merkel cells, They have been identified as tactile perceptors 12 June 2008 Year 3 Block Head & Neck 15
