Type 1 T-helper cell predominance in granulomas of Crohn's disease.
Abstract
The pathogenesis of Crohn's disease (CD) is thought to be associated with production of several cytokines, especially type-1 cytokines. To elucidate the in situ cytokine profiles in CD, cytokine-containing cells were localized by immunohistochemistry, with special attention to noncaseating granulomas. The results were compared with those from studies of ulcerative colitis (UC).
