Abstract The inflammasomes induce maturation of pro-interleukin-1β (IL-1β) and pro-IL-18. We investigated roles the NLRP3 inflammasome in pathogenesis ulcerative colitis (UC). After induction oxazolone-induced colitis, a mouse UC model, colonic tissues were assayed for inflammatory mediators. Histological studies performed on inflamed tissue from mice patients. severity murine peaked day 1, accompanied by an increase expression Th2 cytokines including IL-4 IL-13. Oxazolone treatment...

Abstract Rings or arcs of fungus‐stimulated plant growth occur worldwide; these are commonly referred to as “fairy rings”. In 2010, we discovered 2‐azahypoxanthine (AHX), a compound responsible for the fairy‐ring phenomenon caused by fungus; AHX stimulated all plants tested. Herein, reveal isolation and structure determination common metabolite in plants, 2‐aza‐8‐oxohypoxanthine (AOH). is chemically synthesized from 5‐aminoimidazole‐4‐carboxamide (AICA), can be converted into AOH xanthine...

The inflammasome is a large, multiprotein complex that consists of nucleotide-binding oligomerization domain-like receptor (NLR), an apoptosis-associated speck-like protein containing caspase recruitment domain, and pro-caspase-1. Activation the results in cleavage pro-caspase-1 into cleaved caspase-1, which promotes processing pro-interleukin (IL)-1β mature IL-1β. We investigated effects colchicine on non-steroidal anti-inflammatory drug (NSAID)-induced small intestinal injury activation...

High-mobility group box 1 (HMGB1) was initially discovered as a nuclear protein that interacts with DNA chromatin-associated non-histone to stabilize nucleosomes and regulate the transcription of many genes in nucleus. Once leaked or actively secreted into extracellular environment, HMGB1 activates inflammatory pathways by stimulating multiple receptors, including Toll-like receptor (TLR) 2, TLR4, for advanced glycation end products (RAGE), leading tissue injury. Although HMGB1's ability...

Tomato seeds contain steroidal saponins called lycoperosides. However, it currently remains unclear whether lycoperosides exert anti-inflammatory or anti-allergic effects. Therefore, we herein investigated the effects of tomato seed extract (TSE) and lycoperoside H (LH) in Interleukin (IL)-33 transgenic mice. TSE (500 mg/kg) LH (10 was orally administered once a day for 101 days then evaluated mouse behavior, skin symptoms, blood inflammatory cytokines. slightly suppressed scratching while...

Toll-like receptor 2 (TLR2) recognizes conserved molecular patterns associated with both gram-negative and gram-positive bacteria, detects some endogenous ligands. Previous studies demonstrated that in ischemia-reperfusion (I/R) injury of the small intestine, TLR2-dependent signaling exerted preventive effects on damage young mice, but did not have a significant effect neonatal mice. We investigated role TLR2 adult intestine. Wild-type knockout mice at 16 weeks age were subjected to...
