The inflammasomes induce maturation of pro-interleukin-1β (IL-1β) and pro-IL-18. We investigated roles of the NLRP3 inflammasome in the pathogenesis of ulcerative colitis (UC). After induction of oxazolone-induced colitis, a mouse UC model, colonic tissues were assayed for inflammatory mediators. Histological studies were performed on inflamed colonic tissue from mice and UC patients. Histologi...
Previous studies have shown that interleukin-1β (IL-1β) can excite the magnocellular neurosecretory cells (MNCs) of the hypothalamus. However it is not known if IL-1β can have direct IL-1 receptor type 1 (IL-1R1)-mediated effects on MNCs, and little is known about the cellular mechanisms by which IL-1β influences electrical activity in these cells. Here we used patch-clamp recordings to examine...
INTRODUCTION In this study, we tested the ability of small molecule inhibitors of WNT/β-catenin signaling to block interleukin 1β (IL-1β)- and tumor necrosis factor α (TNFα)-induced cartilage degradation. Proinflammatory cytokines such as IL-1β and TNFα are potent inducers of cartilage degradation by upregulating matrix metalloproteinase (MMP) expression and activity. Because WNT/β-catenin sign...
Agaricus blazei Murill (AbM) has been reported to possess immune activity against tumors and infections through stimulation of mononuclear phagocytes. Recently, AbM extract was shown to induce the production of the pro-inflammatory cytokine, interleukin-1β (IL-1β), in human monocytes. IL-1β is a key pro-inflammatory cytokine produced by activated macrophages and monocytes and its secretion is s...
BACKGROUND IL-1β is an essential factor of inflammation initiation, and it also promotes malignant transformation, indicating its tumorigenic property. We aimed to investigate the correlation between IL-1β and miR-144-3p as well as their prognostic values in LUAD and LUSC patients. RESULTS The IL-1β level in both LUAD and LUSC patients was significantly higher than that of healthy donors (P <...
Interleukin-1β (IL-1β) is a well characterized sleep regulatory substance. To study receptor mechanisms for the sleep-promoting effects of IL-1β, sleep patterns were determined in control and IL-1 type I receptor knockout (IL-1RI KO) mice with a B6x129 background after intraperitoneal injections of saline or murine recombinant IL-1β. The IL-1RI KO mice had slightly but significantly less sleep ...
Aconitum kusnezoffii used as an analgesic and anti-inflammatory. It is often not only in Mongolian medicine but also traditional Chinese medicine. However, there are few studies on its impact of inflammatory cytokines. This study explored the effects vitro human colon cancer (Caco-2) cells. Cytotoxicity was assessed by measuring expression IL-1β, IL-6, IL-8, TNF-α enzyme-linked immunosorbent as...
Maternal immune activation (MIA) results in the development of autism in the offspring via hyperactivation of IL-6 signaling. Furthermore, experimental studies showed that the MIA-associated activation of interleukin-1β (IL-1β) concurrently with IL-6 increases the rate and the severity of hippocampal kindling in mice, thus, offering an explanation for autism-epilepsy comorbidity. We examined wh...
BACKGROUND Inflammation and infection are major determinants of disease severity and consequently, the quality of life and outcome for patients with cystic fibrosis (CF). Interleukin-1 beta (IL-1β) is a key inflammatory mediator. Secretion of biologically active IL-1β involves inflammasome-mediated processing. Little is known about the contribution of IL-1β and the inflammasomes in CF inflammat...
background: leishmania is a significant health problem in many parts of the world. tumor necrosis factor (tnf) plays an essential role in leishmania major infections. objective: to study the pro-inflammatory cytokines and antioxidants in four groups of cutaneous leishmaniasis patients. methods: 39 patients were divided into four groups of: 1) active (acute phase of treatment); 2) non-healing (r...
