title: Study on IL-4, IL-5 and IL-10 in liver and bone marrow of mice infected with Schistosomiasis Japonica.
abstract: To compare Th2 cytokines levels in livers and bone marrow of mice infected with Schistosomiasis Japonica and understand their implication, ABC immunohistochemical staining technique and multimedia pathologic pictures analysis were used to detect the IL-4, IL-5 and IL-10 derived from livers and bone marrow of infected mice. Results showed that in the livers of infected mice, IL-4, IL-5 and IL-10 were obviously increased over time. The level of IL-4 was increased most among the 3 indicators. In bone marrow of infected mice, however, even though IL-4 was slowly increased over time, it was lower than that of livers in 10th and 12th week. The level of IL-5 was higher than that of livers during 12th weeks. Before 10th weeks IL-10 was elevated. After 12th week IL-10 was decreased and obviously lower than that of livers. It is concluded that in mice infected with Schistosomiasis Japonica, the immune response occurred mainly in the liver. Therefore, in bone marrow, IL-5 showed obvious auto-secretion. It might be related to its biological ability to induce B cell division and eosinophil differentiation.
