Objectives. Prehypertension is an early stage of hypertension that is characterized by inflammatory factors. Inflammation also plays an essential role in the development of coronary atherosclerosis (CAS). The present study evaluated the NALP3-inflammasome and its related genes, NLRP3, NOD2, and CARD8, using SNP linkage and gene haplotypes in prehypertensive patients. Methods. A total of 576 pat...

Nucleotide-binding domain (NBD) leucine-rich repeat (LRR)-containing receptors or NLRs are a family of receptors that detect both, molecules associated to pathogens and alarmins, and are located mainly in the cytoplasm. NOD2 belongs to the NLR family and is a dynamic receptor capable of interacting with multiple proteins and modulate immune responses in a stimuli-dependent manner. The experimen...

BACKGROUND Epicutaneous (EC) immunization offers a new method of a needle-free and self-administrable immunization by using a topically applied patch to deliver vaccine. We have previously shown that EC immunization with hapten-conjugated protein antigen TNP-Ig prior to hapten sensitization inhibits Th1-mediated contact hypersensitivity (CHS) in mice. Our further work showed that EC immunizatio...

Risk alleles for complex diseases are widely spread throughout human populations. However, little is known about the geographic distribution and frequencies of risk alleles, which may contribute to differences in disease susceptibility and prevalence among populations. Here, we focus on Crohn's disease (CD) as a model for the evolutionary study of complex disease alleles. Recent genome-wide ass...

NOD2 (nucleotide-binding and oligomerization domain 2) was initially reported as a susceptibility gene for Crohn's disease, with several studies focused on elucidating its molecular mechanism in the progression of Crohn's disease. We now know that NOD2 is an intracellular bacterial sensing receptor, and that MDP-mediated NOD2 activation drives inflammatory signaling. Various mutations in NOD2 h...

AIM To evaluate the inflammatory state in Crohn's disease (CD) patients and correlate it with genetic background and microbial spreading. METHODS By means of flow cytometry, production of tumor necrosis factor-alpha (TNF-α) was measured in peripheral blood monocytes from patients suffering from CD, ulcerative colitis (UC) and in healthy subjects after stimulation of the NOD2 and TLR pathways....

Blau syndrome is a rare autosomal dominant autoinflammatory granulomatous disease caused by the mutation in NOD2 gene and characterized clinical triad of dermatitis, arthritis, uveitis. Since efficacy Janus kinase inhibitors (JAKi) has recently been reported for addition to idiopathic sarcoidosis, we evaluate effect tofacitinib, pan JAKi, on inflammatory pathways associated with syndrome. First...

Mutations in the Nod2 gene are among the strongest genetic risk factors in the pathogenesis of ileal Crohn's disease, but the exact contributions of Nod2 to intestinal mucosal homeostasis are not understood. Here we show that Nod2 plays an essential role in controlling commensal bacterial flora in the intestine. Analysis of intestinal bacteria from the terminal ilea of Nod2-deficient mice showe...

MDP (muramyl dipeptide), a component of peptidoglycan, interacts with NOD2 (nucleotide-binding oligomerization domain 2) stimulating the NOD2-RIP2 (receptor-interacting protein 2) complex to activate signalling pathways important for antibacterial defence. Here we demonstrate that the protein kinase activity of RIP2 has two functions, namely to limit the strength of downstream signalling and to...

Background Nucleotide-binding oligomerization domain-containing protein 2 (NOD2) may play an important role in the outcome of kidney cancer patients. To explore the relationship between NOD2 and the prognosis of kidney cancer patients, a databank-based reanalysis was conducted. Materials and Methods Data related to kidney cancer patients at least with survival information, was obtained mainly...
