Aprepitant is a selective SP/NK-1 receptor antagonist and used in postoperative and chemotherapeutics induced emesis and vomiting. The aim of our study is to show aprepitant may have beneficial effects on gastrointestinal complaints in cancer patients undergoing chemotherapeutics by indomethacin-induced gastric ulcer model. A total of 48 rats were fasted 24 h for ulcer experiment. Aprepitant doses of 5, 10, 20, and 40 mg/kg were evaluated for their antiulcer activity. Omeprazole (20 mg/kg) was used as a positive control group...

BACKGROUND: Anti-tumour necrosis factor-alpha (anti-TNF) antagonists have been the mainstay in the treatment of inflammatory bowel diseases (IBDs) for over 20 years. SUMMARY: This review article aimed to provide an update on recent advances in TNF antagonist therapy for IBDs. Key Messages: Their position in the treatment algorithm has evolved to "rapid step-up therapy" or "top-down therapy" according to disease severity and patients' characteristics...

AIM: Omapatrilat is an antagonist of angiotensin-converting (ACE) and neprilysin-neuropeptidase (NEP) enzymes. The aim of our study is to show that omapatrilat may have beneficial effects as a treatment for polymicrobial sepsis. MAIN METHODS: A cecal ligation and puncture (CLP) sepsis model was used to evaluate 10 and 20 mg/kg doses of omapatrilat in mice (n = 30) fasted for 12 h. The lungs were removed 12 h after CLP, and lung levels of cytokines (tumor necrosis factor-alpha [TNF-α], interleukin-6 [IL-6], NF-κB), iNOS and eNOS mRNA expression, GSH and MDA levels, and ACE and NEP activities were determined...

Toll-like receptor 4 (TLR4) recognizes various endogenous and microbial ligands and is an essential part in the innate immune system. TLR4 signaling initiates transcription factor NF-κB and production of proinflammatory cytokines. TLR4 contributes to the development or progression of various diseases including stroke, neuropathic pain, multiple sclerosis, rheumatoid arthritis and cancer, and better therapeutics are currently sought for these conditions. In this study, a library of 140 000 compounds was virtually screened and a resulting hit-list of 1000 compounds was tested using a cellular reporter system...

Corona Virus Disease 2019 (COVID-19) pandemic is rapidly spreading all over the world. Excessive immune responses trigger life-threatening cytokine release syndrome (CRS) which can result in overproduction of pro-inflammatory cytokines including tumor necrosis factor alpha (TNFα), interleukin-6 (IL-6), and IL-1β with different pro-inflammatory roles. Anecdotal evidence suggests that the modulation of systemic immune responses may have a potential role in the treatment of patients with COVID-19. Given the importance of the issue and the lack of therapeutic treatment or vaccine; anti-cytokine therapy such as IL-6, TNFα and IL-1 antagonists have been suggested for the alleviation of hyper-inflammation status in these patients...

Acute respiratory distress syndrome (ARDS) is a severe condition with high morbidity and mortality and few interventions. The role of sympathetic stress in the pathogenesis of ARDS has attracted recent research attention. Blockade of alpha-2- or alpha2A-adrenoceptor (α2A-AR) has been shown to attenuate lung injury induced by lipopolysaccharide in rats. However, the mechanism is unclear. We confirmed the role of α2A-AR in ARDS using knockout mice and alveolar macrophages following lipopolysaccharide stimulation to assess the underlying mechanisms...

Castleman's disease is a rare lymphoproliferative syndrome involving several anatomical and clinical entities. We report two cases of Castleman's disease in patients with spondyloarthritis (with and without psoriasis) treated with Tumor Necrosis Factor-alpha blockers. During follow-up, imaging examinations, carried out for disease assessment, fortuitously revealed a pelvic mass close to the psoas or an atypical cervical adenopathy. Both lesions were in moderate hypermetabolism on Positron emission tomography-computed tomography...

With a prevalence of up to 20%, eczematous lesions are the most common skin adverse events of tumor necrosis factor alpha inhibitors. Eczematous lesions triggered by more modern biologics such as the IL17A antagonist secukinumab have been rarely reported. Herein, a case of secukinumab-induced pompholyx in a psoriasis patient is presented.

Blau syndrome, or early-onset sarcoidosis, is hereditary juvenile-onset systemic granulomatosis. Clinical symptoms appear before the age of 4 years and mainly affect the skin, joints, and eyes. The symptoms are progressive and cause severe complications, such as joint destruction and blindness. Although tumor necrosis factor alpha (TNFα) antagonists are effective for controlling some of the symptoms of Blau syndrome, there is no specific curative treatment. Heterozygous mutations in nucleotide-binding oligomerization domain 2 (NOD2) were identified as the cause of Blau syndrome onset...

A potential role for leptin in the pathophysiology of bipolar disorder (BD) has been proposed. We recently investigated the effects of the tumor necrosis factor-alpha (TNF-α) antagonist infliximab in individuals with bipolar depression. Leptin is known to interact with the TNF-α system. Herein, we aimed to explore infliximab's effects on leptin and its relationship with brain structure and function. Sixty adults with bipolar depression were enrolled in this randomized, double-blind, 12-week clinical trial of adjunctive infliximab (n = 29) and saline control (n = 31), which were administered intravenously at weeks 0, 2, and 6...

BACKGROUND & AIMS: Unregulated activity of interleukin 22 (IL22) promotes intestinal tumorigenesis in mice. IL22 binds the antagonist IL22 subunit alpha 2 (IL22RA2, also called IL22BP). We studied if alterations in IL22BP contribute to colorectal carcinogenesis in humans and mice. METHODS: We obtained tumor and non-tumor tissues from patients with colorectal cancer (CRC) and measured levels of cytokines by quantitative PCR, flow cytometry, and immunohistochemistry...

Microglia, the resident immune cells in the central nervous system, play a critical role under physiological conditions, but they may be activated and exaggerate the pathological development of Parkinson's disease (PD). Recent reports have suggested that neurokinin 1 receptor (NK1R) is involved in various inflammatory diseases, including PD. However, whether neurokinin 1 (NK1) is involved in the activation of microglial cells remains unclear. In the present study, we found that (1) NK1R is located in microglial cells and upregulated in lipopolysaccharide (LPS)-activated BV2 microglia...

Chronic infantile neurological, cutaneous and articular (CINCA) syndrome is a rare autoinflammatory disease caused by monogenic defects in the NLRP3 gene. Pro-inflammatory cytokines such as interleukin (IL)-1β play a crucial role in the pathogenesis, and IL-1 receptor antagonists have been regarded as the mainstay therapy. Endogenous tumor necrosis factor (TNF)-α was found recently to be involved in the onset of the disease. Here, we report two Chinese children with CINCA syndrome who had elevated serum levels of TNF-α, with one carrying a novel mutation of c...

Subarachnoid hemorrhage (SAH) is a devastating cerebral event caused by an aneurysmal rupture. In addition to neurological injury, SAH has significant effects on cardiac function and the peripheral microcirculation. Since these peripheral complications may exacerbate brain injury, the prevention and management of these peripheral effects are important for improving the overall clinical outcome after SAH. In this investigation, we examined the effects of SAH on cardiac function and vascular reactivity in a well-characterized blood injection model of SAH...

Several studies have shown that 17β-estradiol (E2) exerted beneficial effects on liver disease, and it has a protective impact on brain damage after traumatic brain injury (TBI). TBI-induced liver injury is associated with the activation of TLR4. However, it remains unknown whether E2 can modulate TBI-induced liver injury through TLR4. The objective of this study was to determine the role of TLR4 in hepatoprotective mechanisms of E2 after TBI. Diffuse TBI induced by the Marmarou model in male rats. TAK-242 as a selective antagonist of TLR4 (3mg/kg) and E2 (33...
