This study was conducted to investigate the effects of interferon (IFN)-γ on normal colonic lamina propria lymphocyte subsets in humans using organ culture method. Lamina propria lymphocyte subsets in normal colonic biopsy tissues receiving 1×105 u/ml of IFN-γ (IFN-γ-treated group) were investigated in comparison with those cultured in medium only (IFN-γ-non-treated group) for 24 hr. CD8-positive cells and IgG, IgAl and 1gM-containing cells were elevated in the IFN-γ-treated group compared with those in the IFN-γ-non-treated group, which was similar to immunological changes in mucosal lesions of inflammatory bowel disease.
