Interleukin-9 enhances resistance to the intestinal nematode Trichuris muris.
Upon infection with the cecum-dwelling nematode Trichuris muris, the majority of inbred strains of mice launch a Th2-type immune response and in doing so expel the parasite before patency. In contrast, there are a few mouse strains which develop a nonprotective Th1-type response resulting in a chronic infection and the presence of adult worms. Of the Th2 cytokines known to be associated with th...
متن کاملB cells and antibodies are required for resistance to the parasitic gastrointestinal nematode Trichuris muris.
Previous studies using cell transfers and antibody receptor knockout mice have shown that B cells and antibodies are not essential components of the expulsion mechanism in Trichuris muris infections. Serum transfer experiments have given mixed results regarding the importance of antibodies in this infection model, and the role of B cells in initiating or maintaining T-cell responses has not bee...
متن کاملRapid dendritic cell mobilization to the large intestinal epithelium is associated with resistance to Trichuris muris infection.
The large intestine is a major site of infection and disease, yet little is known about how immunity is initiated within this site and the role of dendritic cells (DCs) in this process. We used the well-established model of Trichuris muris infection to investigate the innate response of colonic DCs in mice that are inherently resistant or susceptible to infection. One day postinfection, there w...
متن کاملSerine Protease(s) Secreted by the Nematode Trichuris muris Degrade the Mucus Barrier
The polymeric mucin component of the intestinal mucus barrier changes during nematode infection to provide not only physical protection but also to directly affect pathogenic nematodes and aid expulsion. Despite this, the direct interaction of the nematodes with the mucins and the mucus barrier has not previously been addressed. We used the well-established Trichuris muris nematode model to inv...
متن کاملArginase-1-expressing macrophages are dispensable for resistance to infection with the gastrointestinal helminth Trichuris muris
Alternatively activated macrophages (AAMs) have key roles in the immune response to a variety of gastrointestinal helminths such as Heligmosomoides bakeri and Nippostrongylus brasiliensis. In addition, AAMs have been implicated in the resolution of infection-induced pathology in Schistosoma mansoni infection. AAMs exert their activity in part via the enzyme arginase-1 (Arg1), which hydrolyses L...
