Abstract:
:T cell subsets in peripheral blood were phenotyped in 56 patients with different stages of Schistosomiasis japonica, including 17 with acute, 14 with chronic and 25 with advanced infection. The activity of interleukin-1 (IL-1) produced by peripheral blood mononuclear cells (PBMC) induced by lipopolysaccharide (LPS) in vitro was simultaneously detected in these three groups of patients. It was found that the percentages of CD3+ (total T cell), CD4+ (helper/inducer T cell) and CD8+ (suppressor/cytotoxic T cell) T cell and the level of IL-1 were significantly increased in the group of acute Schistosomiasis japonica. In the groups of chronic and advanced Schistosomiasis japonica, the proportion of CD3+ T cell, the ratio of CD3+/CD4+ and the level of IL-1 were remarkably reduced, and the percentage of CD8+ T cell was increased. The rate of CD4+ T cell was obviously decreased in cases patients with advanced Schistosomiasis japonica. The percentage of CD4+ T cell was positively correlated to the level of IL-1 in the three groups of patients. These results indicate that T cell subsets and IL-1 may play an important role in the immunoregulation of Schistosomiasis japonica.
