Selective death of T cell receptor gamma/delta+ intraepithelial lymphocytes by apoptosis
1Department of Paediatric Gastroenterology, St. Bartholomews Hospital, London, GB.
In mice, the majority of T cells expressing the gamma/delta T cell receptor (TcR) are found at mucosal surfaces, especially the intestinal epithelium. Here we show that in vitro, the majority of TcR gamma/delta+ intraepithelial lymphocytes, but not TcR alpha/beta+ intraepithelial lymphocytes, undergo rapid and selective programmed cell death by apoptosis.
