Expression of SIgA positive cells, CD3+T cells, DC's. Immunohistochemical staining of SIgA positive cells and CD3+T cells, and immunofluorescent staining of DCs in the jejunum. a Changes in SIgA positive cells after TGEV infection. b Changes in CD3+T cells. Positive cells were quantified by densitometry analysis, and were calculated in 10 random fields. IOD: Integrated optical density. c Number of SLA-II-DR+SWC3a+DCs. Scale bars: 50 μm. Differences were considered significant at (*) 0.01 < p < 0.05, (**) p < 0.01
