Background
Immune cells are important for the development of schistosomiasis japonica and are also critical for the treatment of schistosomiasis. The immune cells in the peripheral blood help assess the immune state. The peripheral lymphocytes in schistosomiasis mansoni were well studied, however immune cells in patients with different stages of Schistosomiasis Japonica are not well analyzed. Here we performed a preliminary study to explore characteristics of peripheral lymphocyte subsets in patients with different stages of Schistosomiasis Japonica.
