Abstract

The oral cavity is a septic area colonized by various bacterial species, and the oral mucosa is frequently submitted to microtraumas. Several mechanisms are implicated in the defence of the oral tissue, but little is known concerning the eventual presence and role of gamma/delta T cells at this site. Samples of healthy keratinized oral mucosa were examined with immunochemical techniques using anti-CD3, CD4, CD8, CD22, TcR delta 1, V delta 1 and V delta 2 monoclonal antibodies. Whatever the site examined, gamma/delta T cells represent at most 2% of the T-cell population, a value similar to that found in other tissues. In the connective tissue, under the basement membrane, V delta 2+ gamma/delta T cells are predominant whereas the epithelium mostly contains V delta 1+ gamma/delta T cells. The significance of this preferential V delta 1 intraepithelial presence is discussed.
