TNF alpha antagonists

BACKGROUND: Androgen deprivation therapy (ADT) is the mainstay treatment for advanced prostate cancer. But ADTs with orchiectomy and gonadotropin-releasing hormone (GnRH) agonist are associated with increased risk of cardiovascular diseases, which appears less significant with GnRH antagonist. The difference of follicle-stimulating hormone (FSH) in ADT modalities is hypothesized to be responsible for ADT-associated cardiovascular diseases. METHODS: We administered orchiectomy, GnRH agonist, or GnRH antagonist in male ApoE-/- mice fed with Western diet and manipulated FSH levels by testosterone and FSH supplementation or FSH antibody to investigate the role of FSH elevation on atherosclerosis...

Tumor necrosis factor alpha (TNF- α) inhibitors are widely employed for the management of chronic inflammatory rheumatism. However, their usage carries significant risks, including site and infusion reactions, serious infections, malignancy, heart failure autoimmune and demyelinating disorders. These risks are comprehensively outlined in risk management plans (RMPs) associated with these molecules. RMP provides information on the safety profile of a medicinal product as well as the measures that will be taken to minimize risks; these are known as risk minimization measures...

Rheumatoid arthritis (RA) is an autoimmune disease characterized by aggressive cartilage and bone erosion. This work aimed to evaluate the metabolomic profile of Medicago sativa L. (MS) seeds and explore its therapeutic impact against RA in rats. Arthritis was induced by complete Freund's adjuvant (CFA) and its severity was assessed by the arthritis index. Treatment with MS seeds butanol fraction and interlukin-1 receptor antagonist (IL-1RA) were evaluated through measuring interlukin-1 receptor (IL-1R) type 1 gene expression, interlukin-1 beta (IL-1β), oxidative stress markers, C-reactive protein (CRP), tumor necrosis factor-alpha (TNF-α), prostaglandin E2 (PGE2), caspase-3 (Cas-3), intracellular adhesion molecule-1 (ICAM-1), DNA fragmentation, and chromosomal damage...

ETHNOPHARMACOLOGICAL RELEVANCE: In elderly people, Alzheimer's disease (AD) is the most common form of dementia. It has been shown that traditional Chinese medicine (TCM) based on phytomedicines enhances the therapeutic effects of modern medicine when taken in conjunction with them. Modern medicine N-methyl-D-aspartate receptor (NMDA) antagonist memantine (Mm) are mainly used in the clinical treatment of AD. TCM Cerebralcare Granule® (CG) has long been an effective treatment for headaches, dizziness, and other symptoms...

OBJECTIVE: This study aimed to assess the antinociceptive activity of herbacetin using chemically and thermally induced nociception in a mouse model. MATERIALS AND METHODS: The antinociceptive effects of various herbacetin doses (50, 100, 150, and 200 µg/kg) were assessed in mice using the acetic acid-induced writhing test, hot plate test, and formalin-induced paw-licking assay. The effects were compared to those of mice treated with acetylsalicylic acid or morphine in the presence or absence of naloxone (an opioid receptor antagonist)...

BACKGROUND: In recent years, particulate matter 2.5 (PM2.5) exposure has been considered a key dangerous factor in chronic obstructive pulmonary disease (COPD). The dysfunction of airway smooth muscle cells (ASMCs) facilitates lung inflammation and fibrosis in COPD. Therefore, we explored whether PM2.5 could promote the inflammatory response and fibrosis in ASMCs in vivo and in vitro via the wingless-related integration site 5a (Wnt5a)/c-Jun N-terminal kinase (JNK)/nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) pathway...

Combination therapy with glucocorticoids, cyclophosphamide, and plasmapheresis is recommended as the standard treatment for anti-glomerular basement membrane (anti-GBM) disease, but the prognosis of this disease remains poor. Several immunobiological agents have been administered or are expected to be useful for anti-GBM disease in light of refractory disease or the standard treatments' tolerability. Many data regarding the use of biologic agents for anti-GBM disease have accumulated, verifying the effectiveness and potential of biologic agents as a new treatment option for anti-GBM disease...

BACKGROUND: Many drugs have been explored for their role in improving skin flap survival. 1-deamino-8-D-arginine vasopressin (DDAVP or desmopressin) is a synthesized form of anti-diuretic hormone (ADH) and a selective agonist for vasopressin type-2 receptors (V2 receptors). Desmopressin has been shown to improve endothelial function, induce vasodilation, and reduce inflammation. We aimed to evaluate its efficacy in enhancing flap survival and assess the role of vasopressin receptors in this process...

Tumor necrosis factor-α (TNF-α) antagonists are highly effective in controlling autoimmune diseases. This has led to speculation that they might also be useful in treating inflammatory placental conditions, such as chronic villitis of unknown etiology (VUE). VUE affects 10-15% of term placentas and is associated with recurrent fetal growth restriction (FGR) and pregnancy loss. We aimed to evaluate outcomes in patients with autoimmune diseases with and without anti-TNF-α biologic exposure during gestation...

BACKGROUND: As a chronic inflammatory disease, psoriasis affects not only the skin but also the metabolic profile of the patients. Biologic therapies, including tumor necrosis alpha (TNF-a) inhibitors and interleukin (IL)-12/23 and IL-17 antagonists, have proven effective in the reduction of psoriasis severity; however their impact on the metabolic and chronic inflammatory profiles of the patients remains incompletely elucidated. METHODS: We performed a longitudinal case-control study on 106 psoriasis patients and an equal number of controls without the disease, as well as a prospective study on the patient group with the end point being 6 months of biologic therapy...

BACKGROUND: Our previous research proved that vagus nerve stimulation (VNS) improved the neurological outcome after cardiopulmonary resuscitation (CPR) by activating α7 nicotinic acetylcholine receptor (α7nAChR) in a rat model, but the underlying mechanism of VNS in neuroprotection after CPR remains unclear. METHODS: In vivo , we established a mouse model of cardiac arrest (CA)/CPR to observe the survival rate, and the changes in inflammatory factors and brain tissue after VNS treatment...

Nonalcoholic fatty liver disease (NAFLD) is emerging as an important risk factor for hepatocellular carcinoma (HCC), whose prevalence is rising. Although the mechanisms of progression from NAFLD to HCC are not fully elucidated, tumor necrosis factor-α (TNF-α) and adiponectin, as well as their interplay, which seems to be antagonistic, may contribute to the pathophysiology of NAFLD-associated HCC. TNF-α initially aims to protect against hepatocarcinogenesis, but during the progression of NAFLD, TNF-α is increased, thus probably inducing hepatocarcinogenesis in the long-term, when NAFLD is not resolved...

The communication between the nervous and immune systems plays a crucial role in regulating immune cell function and inflammatory responses. Sympathetic neurons, which innervate the spleen, have been implicated in modulating immune cell activity. The neurotransmitter norepinephrine (NE), released by sympathetic neurons, influences immune cell responses by binding to adrenergic receptors on their surface. The alpha-2 adrenergic receptor (α2AR), expressed predominantly on sympathetic neurons, has received attention due to its autoreceptor function and ability to modulate NE release...

Endometriosis is a chronic inflammatory gynecologic condition among women of reproductive age causing a plethora of symptoms that significantly affect their quality of life and mental health. Recent literature reports mounting evidence for several inflammation-mediated pathways for endometriosis pathogenesis, where elevated levels of proinflammatory factors, such as intercellular adhesion molecule 1, tumor necrosis factor-alpha, and nuclear factor kappa B have been established. Simultaneously, the prevalent clinical use of H1-antihistamines for other pathologies along with active research into its action pathways has led to our current understanding that H1-antihistamines counteract several inflammation mediators, including intercellular adhesion molecule 1, tumor necrosis factor-alpha, and nuclear factor kappa B...

Sepsis-associated encephalopathy (SAE) is the most common complication of sepsis, with increased morbidity and mortality. To date, there has still been no established pharmacological therapy. Memantine, as an NMDA ( N -methyl-d-aspartate) receptor antagonist, exhibited neuroprotective effects against cognitive and emotional dysfunction in many disorders. We performed cecal ligation and puncture (CLP) inducing sepsis as the ideal animal model of SAE. CLP-induced septic mice were given a memantine treatment through intragastric administration...

The study objective was to evaluate the interaction between corticotrophin releasing factor ( CRF ) receptor signaling and prophylactic antibiotic administration on intestinal physiology in newly weaned and transported pigs. Pigs (n = 56; 5.70 ± 1.05 kg) were weaned (20.49 ± 0.64 d), a blood sample was taken, and then pigs were given an intraperitoneal injection of saline ( SAL ; n = 28 pigs) or a CRF receptor antagonist ( CRFA ; n = 28 pigs; 30 μg/kg body weight; Astressin B), and then were transported in a livestock trailer for 12 h and 49 min...

BACKGROUND: There are many adverse reactions in the treatment of allergic rhinitis (AR) mainly with conventional drugs. Leukotriene receptor antagonists, glucocorticoids and nasal antihistamines can all be used as first-line drugs for AR, but the clinical effects of the three drugs are not clear. AIM: To examine the impact of glucocorticoids, antihistamines, and leukotriene receptor antagonists on individuals diagnosed with AR, specifically focusing on their influence on serum inflammatory indexes...

Acute lymphoblastic leukemia (ALL) is the most common childhood cancer. Although its prognosis continually improves with time, a significant proportion of patients still relapse from the disease because of the leukemia's resistance to therapy. Methotrexate (MTX), a folic-acid antagonist, is a chemotherapy agent commonly used against ALL and as an immune-system suppressant for rheumatoid arthritis that presents multiple and complex mechanisms of action and resistance. Previous studies have shown that MTX modulates the nuclear factor kappa B (NF-κB) pathway, an important family of transcription factors involved in inflammation, immunity, cell survival, and proliferation which are frequently hyperactivated in ALL...

BACKGROUND: it has been suggested that chronic low-grade inflammation plays an important role in the pathogenesis of polycystic ovary syndrome (PCOS). According to previous studies, it remains unclear which cytokines influence the development of this syndrome and whether their increase is associated with the presence of excess weight/obesity or is an independent factor. The aim of our research was to determine the parameters of chronic inflammation in women with PCOS in comparison with healthy women in the normal weight and the overweight subgroups...

CXCL14 (C-X-C motif chemokine ligand 14) is an important chemokine involved in infection and immunity and plays an important role in a variety of immune-related diseases. The 446 bp cDNA sequence of the CXCL14 gene in yaks was obtained. Additionally, the prokaryotic expression vector of the CXCL14 protein with a molecular weight of 27 kDa was successfully constructed and expressed. The proliferation activities and migration abilities of spleen macrophages were significantly inhibited after treatment with the CXCL14 protein at different concentrations (1, 10 and 20 μg/mL) ( p < 0...
