P. Hoang et al., CYTOKINE PRODUCTION BY HUMAN COLONIC INTRAEPITHELIAL LYMPHOCYTES IN CONTROLS AND ULCERATIVE-COLITIS, Mediators of inflammation, 3(3), 1994, pp. 219-222
USING an ELISA technique, concentrations of gamma-interferon and inter
leukin-2 were assayed in the supernatants of colonic intraepithelial l
ymphocytes cultured with or without phytohaemagglutinin (PHA). Intraep
ithelial lymphocytes produced low concentrations of gamma-interferon a
nd interleukin-2 when stimulated with PHA, but significantly more than
when unstimulated (p < 0.05). There was no difference in production o
f these cytokines by IEL from control or inflammatory bowel disease.
