It is essential to distinguish the role of T lymphocytes on the physiopathology associated to more severe forms of schistosomiasis and on the immunomodulation that evolves in the majority of infected people. In this study, we generatedSchistosoma mansoni-specific T cell lines and clones from patients with the acute and chronic (intestinal and hepatosplenic forms) phases of disease, from former ones, and from uninfected individuals sensitized to parasite soluble antigens.

The cytokine analysis of CD4+T cell clones revealed a Th2/Th0pattern (clones producing IL-4 and IL-5 and clones producing all three cytokines) for those derived from infected patients, while cells from antigen-sensitized donors exhibited an opposite Th1/Th0pattern (clones producing IFN-γ and clones producing all three cytokines). The possible role of these T cell populations on human schistosomiasis mansoni is discussed.

Abstract
It is essential to distinguish the role of T lymphocytes on the physiopathology associated to more severe forms of schistosomiasis and on the immunomodulation that evolves in the majority of infected people. In this study, we generatedSchistosoma mansoni-specific T cell lines and clones from patients with the acute and chronic (intestinal and hepatosplenic forms) phases of disease, from former ones, and from uninfected individuals sensitized to parasite soluble antigens. T cell lines derived from nontreated acute infected donors were capable of producing IL-4 and IL-5, while cells from treated patients secreted IFN-γ. Lines from intestinal chronic and antigen-sensitized donors preferentially produced IFN-γ, while those from hepatosplenic patients secreted all three cytokines. The cytokine analysis of CD4+T cell clones revealed a Th2/Th0pattern (clones producing IL-4 and IL-5 and clones producing all three cytokines) for those derived from infected patients, while cells from antigen-sensitized donors exhibited an opposite Th1/Th0pattern (clones producing IFN-γ and clones producing all three cytokines). The possible role of these T cell populations on human schistosomiasis mansoni is discussed.File | Dimensione | Formato | |
