The term in ammatory bowel diseases (IBD) refers to a group of idiopathic, chronic intestinal diseases characterized by a di use in ltration of in ammatory cells into the lamina propria of the intestine. The pathogenesis of IBD is unknown. The most common signs described are diarrhoea, vomit, and progressive weight loss. In order to make a de nitive diagnosis, though, the presence of in ammatory cells in ltration must be evident on histopathologic analysis. The therapeutic approach has 2 main goals: decrease the in ammatory response and remove possible antigenic sources, such as food components or intestinal micro ora...

The inflammatory response is probably one of the main destructive events occurring after spinal cord injury (SCI). Its progression depends mostly on the autoimmune response developed against neural constituents. Therefore, modulation or inhibition of this self-reactive reaction could help to reduce tissue destruction. Anterior chamber associated immune deviation (ACAID) is a phenomenon that induces immune-tolerance to antigens injected into the eye´s anterior chamber, provoking the reduction of such immune response...

BACKGROUND: Coronary artery bypass (CAB) surgery triggers systemic inflammatory response syndrome (SIRS) via several mechanisms. Moreover, age is directly correlated with SIRS. We evaluated the effect of age on SIRS and postoperative outcome after CAB surgery. METHODS: We retrospectively reviewed the records of 229 patients who had undergone CAB surgery. The patients were divided into three groups according to age: group 1, < 40 years (n = 61); group 2, 40-75 years (n = 83); and group 3, > 75 years old (n = 85)...

Because of the paucity of information regarding metabolic effects of advanced glycation end products (AGEs) on liver, we evaluated effects of AGEs chronic administration in (1) insulin sensitivity; (2) hepatic expression of genes involved in AGEs, glucose and fat metabolism, oxidative stress and inflammation and; (3) hepatic morphology and glycogen content. Rats received intraperitoneally albumin modified (AlbAGE) or not by advanced glycation for 12 weeks. AlbAGE induced whole-body insulin resistance concomitantly with increased hepatic insulin sensitivity, evidenced by activation of AKT, inactivation of GSK3, increased hepatic glycogen content, and decreased expression of gluconeogenesis genes...

INTRODUCTION: The inflammatory response is closely intertwined with the process of repair. However in some diseases the inflammatory response may be exaggerated and sustained without apparent benefit and even with severe adverse complications. For decades, we have been primarily relying upon Nonsteroidal (NSAID) and Steroidal Anti-Inflammatory agents for management of various inflammatory conditions. However, adverse effects of these drugs are severe which often leads to patient's non-compliance with inadequate relief...

IκBζ, an atypical member of the nuclear IκB family of proteins, is expressed at low levels in most resting cells, but is induced upon stimulation of Toll-like/IL-1 receptors through an IRAK1/IRAK4/NFκB-dependent pathway. Like its homolog Bcl3, IκBζ can regulate the transcription of a set of inflamatory genes through its association with the p50 or p52 subunits of NF-κB. Long studied as a key component of the immune response, IκBζ emerges as an important regulator of inflammation, cell proliferation and survival...

Morbid obesity (MO) is associated with an increase in circulating levels of systemic acute phase proteins such as C-reactive protein (CRP). Toll-like receptor is possible candidate for inflammatory responses which is mainly mediated by NFKB1. The aim of this study was to investigate the relationship between NFKB1 and Toll-like receptor (TLR) 2 polymorphisms and the risk of MO in a Turkish population in the context of CRP serum levels which may contribute to susceptibility to the disease. We analysed the distribution of NFKB1-94 ins/del ATTG rs28362491 and TLR2 Arg753Gln rs5743708 polymorphisms using PCR-RFLP method and CRP serum levels using ELISA method in 213 MO and 200 healthy controls...

Preeclampsia is one of the main causes of maternal and perinatal mortality in the world; however, the pathophysiologic pathways haven't been clearly elucidated. It is thought to result from a breakdown of maternal tolerance to paternal antigens in placenta that start an immune response against the trophoblast inducing a defective placentation and a hipoxic/isquemic environment which in turn triggers a systemic inflamatory response. This review gives an overview of the mechanims involved in maternal tolerance, how these are disrupted in preeclampsia, and how they contribute to the inflamatory response...

Chronic inflammation is a hallmark of neurodegenerative disease and cytotoxic levels of nitric oxide (NO) and pro-inflammatory cytokines can initiate neuronal death pathways. A range of cellular assays were used to assess the anti-inflammatory and neuroprotective action of resveratrol using murine microglial (C8-B4), macrophage (RAW264.7) and neuronal-like (Neuro2a) cell lines. We examined the release of NO by Griess assay and used a Bioplex array to measure a panel of pro- and anti-inflammatory cytokines and chemokines, in response to the inflammatory stimuli lipopolysaccharide (LPS) and interferon-γ (IFN-γ)...

Immune thrombocytopenia (ITP) is an autoimmune disease characterized by thrombocytopenia due to platelet autoantibodies, causing an accelerated clearance of opsonized platelets by phagocytes. The etiology of ITP remains unclear, both genetic and environmental factors may have a role in the disease development. The aim of our study was to investigate a possible association of three single nucleotide polymorphisms (SNP) in the genes for interleukin beta (IL1B-511C/T), tumor necrosis factor beta (TNF+252G/A) and tumor necrosis factor alpha (TNFA-308G/A) with ITP...

Regeneration in the central nervous system (CNS) of adult mammalian after traumatic injury is limited, which often causes permanent functional motor and sensory loss. After spinal cord injury (SCI), the lack of regeneration is mainly attributed to the presence of a hostile microenvironment, glial scarring, and cavitation. Besides, inflammation has also been proved to play a crucial role in secondary degeneration following SCI. The more prominent treatment strategies in experimental models focus mainly on drugs and cell therapies, however, only a few strategies applied in clinical studies and therapies still have only limited effects on the repair of SCI...

Trichinella spiralis muscle larvae excretory-secretory antigens (ES L1) are most likely responsible for the induction of immune response during infection by this parasitic. The antigens bear carbohydrate structures that may contribute to immune system activation resulting in a Th2/anti-inflammatory immune response. We show that T. spiralis glycans affect the expression and the production of IL-4 and IL-10 in vivo. Alteration of carbohydrate structures on ES L1 altered dendritic cell (DC) maturation. Periodate treatment of ES L1 led to the reduction in both ERK and p38 phosphorylation which may be the cause of reduced IL-10 and IL-12p70 production...

Periodontitis is a disease that leads to bone destruction and represents the main cause of tooth loss in adults. The development of aggressive periodontitis has been associated with increased inflammatory response that is induced by the presence of a subgingival biofilm containing Aggregatibacter actinomycetemcomitans. The flavonoid quercetin (1) is widespread in vegetables and fruits and exhibits many biological properties for possible medical and clinical applications such as its anti-inflamatory and antioxidant effects...

Acute Kidney Injury (AKI) in trauma is, in most cases, multifactorial. Factors related to the initial ressuscitation protocol, degree of the systemic inflamatory response to trauma, contrast nephropathy in diagnostic procedures, rhabdomyolysis and abdominal compartment syndrome are some of those factors. Nowadays a uniformization in diagnostic criteria for AKI has been proposed by the Acute Kidney Injury Network (AKIN) and as a result the incidence of AKI and its impact in outcomes in trauma patients also needs to be reconsider...

Dexamethasone (DEX) an anti-inflamatory 9-fluoro-glucocorticoid, activates the cytosolic glucocorticoid receptor (GR) binding to its Ligand Binding Domain (LBD). The GR-ligand complex then translocates to the nucleus and binds to the Glucocorticoid Response Element (GRE) resulting up-regulation of target gene expression of anti-inflamatory proteins. DEX is one of the most effective ligand for GR activation but comply to side effects. Therefore, alternative for DEX - plant metabolites of Calotropis sp and Swertia chirata were screened using docking appraoch...
