Abstract:

After infection with Schistosoma japonicum, mature female adult worms lay eggs which deposit in the liver, intestinal wall, and other tissues of the infected mammalian host, which induces predominant Th2 immune responses and causes egg granuloma and fibrosis. It has been reported that neutrophils, macrophages, eosinophils, natural killer cells, B cells (including regulatory B cells), T cells (including Th1, Th2, and Th17 cells), Treg cells, hepatic stellate cells, and hepatocytes are involved in this process. In this paper, we reviewed the cell types involved in the egg granulomatous response of S. japonicum and their possible mechanisms in order to provide a helpful reference for related researchers in this field.

Key words: Schistosoma japonicum, Egg granuloma, Immune response, Pathological mechanism
