BACKGROUND Although the efficacy of standard fish oil has been the subject of research in arthritis, the effect of krill oil in this disease has yet to be investigated. The objective of the present study was to evaluate a standardised preparation of krill oil and fish oil in an animal model for arthritis. METHODS Collagen-induced arthritis susceptible(More)
MicroRNA (miRNA) species (miR) regulate mRNA translation and are implicated as mediators of disease pathology via coordinated regulation of molecular effector pathways. Unraveling miR disease-related activities will facilitate future therapeutic interventions. miR-155 recently has been identified with critical immune regulatory functions. Although detected(More)
Expulsion of the gastrointestinal nematode Trichinella spiralis is associated with Th2 responses and intestinal inflammation, which correlate with a marked mast cell (MC) response. To address the role of MC-derived cytokines in the induction of protective responses, WBB6F1-KitW/KitW-v (W/W(v)) mice were reconstituted with wild-type, tumor necrosis factor(More)
Infections with gastrointestinal helminths elicit potent Th2 responses, which ultimately result in their expulsion. However, during expulsion of Trichinella spiralis this Th2 response also induces a severe enteropathy characterized by villus atrophy and crypt hyperplasia. Inducible costimulator (ICOS), a homologue of CD28, interacts with B7-related protein(More)
To study the specific role of transmembrane tumor necrosis factor (tmTNF) in protective and pathological responses against the gastrointestinal helminth Trichinella spiralis, we compared the immune responses of TNF-alpha/lymphotoxin alpha (LTalpha)(-/-) mice expressing noncleavable transgenic tmTNF to those of TNF-alpha/LTalpha(-/-) and wild-type mice. The(More)
T helper type 2 (Th2) responses have been shown to be important in protective responses to gastrointestinal (GI) helminth infections and in the development of the intestinal pathology accompanying expulsion of the parasite. Different inbred mouse strains have been shown to develop different cytokine profiles following infection with GI helminths with(More)
Previous studies demonstrated that neonatal mice up to about a week old are less susceptible than adult mice to infection by intraperitoneal inoculation with mouse-passaged scrapie. In peripherally inoculated adult mice, scrapie replicates in lymphoid tissues such as the spleen before invading the central nervous system. Here, we investigated scrapie(More)
OBJECTIVE In the present study we evaluated the use of four commercially available fluorescent probes to monitor disease activity in murine CIA and its suppression during glucocorticoid therapy. METHODS Arthritis was induced in male DBA/1 mice by immunization with type II collagen in Complete Freund's Adjuvant, followed by a boost of collagen in PBS. Four(More)
The immune expulsion of gastrointestinal nematode parasites is usually associated with T helper type 2 (Th2) responses, but the effector mechanisms directly responsible for parasite loss have not been elucidated. The intestinal inflammatory response accompanying infection with gastrointestinal helminths is thought to be a contributory factor leading to the(More)
