| Abstrakt: | Abstract: We analyzed the immune response to gliadin in suckling rats and rats hand-fed with an artificial milk formula, an animal model of gluten enteropathy. Animals of both groups were intragastrically given either gliadin or albumin (control animals) or gliadin from birth till day 55. When compared to the controls, spleen lymphocytes from both groups of gliadin-treated rats cultivated in vitro exhibited a significant increase of spontaneous 3H-thymidine incorporation. Moreover, the proliferation of spleen and mesenteric lymph node (MLN) lymhocytes from both groups of gliadin-treated suckling and hand-fed rats was specifically increased by the in vitro gliadin challenge. Spleen B cells from gliadin-treated rats spontaneously produced higher amounts of gliadin-specific antibodies than those from the controls, however, in vitro stimulation by gliadin caused no further increase in antibody production. Apoptotic DNA fragmentation in MLN cells was higher in gliadin-treated rats than in albumin-treated ones, independently of the milk diet during the suckling period. |
