Charcot-Marie-Tooth neuropathy (CMT) is a motor and sensory neuropathy comprising a heterogeneous group of inherited diseases. The CMT1A phenotype is predominant in the 70% of CMT patients, with nerve conduction velocity reduction and hypertrophic demyelination. These patients have elevated oxidative stress and chronic inflammation. Currently, there is no effective cure for CMT; herein, we investigated whether melatonin treatment may reduce the inflammatory and oxidative damage in CMT1A patients. Three patients, aged 8-10 years, were treated with melatonin (60 mg at 21:00 h plus 10 mg at 09:00 h), and plasma levels of lipid peroxidation (LPO), nitrites (NOx), IL-1β, IL-2, IL-6, TNF-α, INF-γ, oxidized to reduced glutathione (GSSG/GSH) ratio, and the activities of superoxide dismutase (SOD), glutathione-S transferase (GST), glutathione peroxidase (GPx), and reductase (GRd), were determined in erythrocytes at 3 and 6 months of treatment...

Indigenous Australians experience high rates of cardiovascular disease (CVD). The origins of CVD may commence during pregnancy, yet few serum reference values for CVD biomarkers exist specific to the pregnancy period. The Gomeroi gaaynggal research project is a program that undertakes research and provides some health services to pregnant Indigenous women. Three hundred and ninety-nine non-fasting samples provided by the study participants (206 pregnancies and 175 women) have been used to construct reference intervals for CVD biomarkers during this critical time...

Several studies have indicated that neuroinflammation is indeed associated with neurodegenerative disease pathology. However, failures of recent clinical trials of anti-inflammatory agents in neurodegenerative disorders have emphasized the need to better understand the complexity of the neuroinflammatory process in order to unravel its link with neurodegeneration. Deregulation of Cyclin-dependent kinase 5 (Cdk5) activity by production of its hyperactivator p25 is involved in the formation of tau and amyloid pathology reminiscent of Alzheimer's disease (AD)...

BACKGROUND: Early detection and differentiation diagnosis of a pelvic mass (PM) is crucial in improving the prognosis of patients with epithelial ovarian cancer (EOC). C-C motif chemokine ligand 18 (CCL18) was reported as a chemokine-mediated tumor-related inflammation that can be detected in serum and may correlate with cancer patients' prognosis. OBJECTIVE: We performed this study to investigate the relationship between CCL18 levels and clinical characteristics of EOC patients, and to explore their diagnostic and prognostic values...

Several microbial molecules with pathogen-associated molecular patterns stimulate host innate immune responses. The innate immune system plays a crucial role in activating acquired immune response via cytokine production and antigen presentation. Previous studies have shown that Aureobasidium pullulans-cultured fluid (AP-CF), which contains β-glucan, exhibits adjuvant activity and renders mice resistance to influenza A virus infection; however, the underlying mechanism remains elusive. In this study, we investigated the innate immune response to AP-CF...

Analyses of immunity in pulmonary arterial hypertension (PAH) support the notion that maladaptation of the immune response exists. Altered immunity is an increasingly recognized feature of PAH. Indeed, a delicate balance between immunity and tolerance exists and any disturbance may result in chronic inflammation or autoimmunity. This is suggested by infiltration of various immune cells (e.g. macrophages, T and B lymphocytes) in remodeled pulmonary vessels. In addition, several types of autoantibodies directed against antinuclear antigens, endothelial cells (ECs) and fibroblasts have been found in idiopathic and systemic sclerosis-associated PAH...

The lung is constantly exposed to ambient pollutants such as ambient fine particulate matter (PM2.5), making it one of the most frequent locations of inflammation in the body. Given the establishment of crucial role of inflammation in the pathogenesis of cardiometabolic diseases, pulmonary inflammation is thus widely believed to be an important risk factor for cardiometabolic diseases. However, the causality between them has not yet been well established. To determine if pulmonary inflammation is sufficient to cause adverse cardiometabolic effects, SFTPC-rtTA+/-tetO-cre+/-pROSA-inhibitor κB kinase 2(IKK2)ca+/- (LungIKK2ca) and littermate SFTPC-rtTA+/-tetO-cre-/-pROSA-IKK2ca+/- wildtype (WT) mice were fed with doxycycline diet to induce constitutively active Ikk2 (Ikk2ca) overexpression in the lung and their pulmonary, systemic, adipose, and hypothalamic inflammations, vascular function, and glucose homeostasis were assessed...

Background: The transcriptional regulation of the human AT1R gene in pathophysiologies, like the metabolic syndrome, is poorly understood. The human AT1R gene has polymorphisms in its promoter that can be arranged in two haplotypes. Variants -810T, -713T, -214A, and -153A always occur together (Hap-I) and variants -810A, -713G, -214C, and -153G form Hap-II. We have hypothesized that high fat diet will alter cellular transcriptional milieu and increase hAT1R gene expression in a haplotype-dependent manner...

The relationship among periodontitis, diabetes mellitus and atherosclerotic cardiovascular disease is complex and can be thought of as a Bermuda triangle. A relationship has been demonstrated between periodontitis, a worsening in the condition of the vascular system and an increased total level of inflammatory markers. Patients with severe periodontitis also show raised levels of glycosylated haemoglobin. This means that severe periodontitis can be an early indication of diabetes mellitus. Periodontal treatment generally promotes improved blood sugar regulation in diabetes patients, an improved condition of the vascular system and a decrease in the total levels of inflammation...

C1 esterase inhibitor (C1-INH) can inhibit multiple pathways (complement, contact-kinin, coagulation, and fibrinolysis) that are all implicated in the pathophysiology of asthma. We explored the effect of human plasma-derived C1-INH on allergic lung inflammation in a house dust mite (HDM) induced asthma mouse model by daily administration of C1-INH (15 U) during the challenge phase. NaCl and HDM exposed mice had comparable plasma C1-INH levels, while bronchoalveolar lavage fluid (BALF) levels were increased in HDM exposed mice coinciding with slightly reduced activation of complement (C5a)...

Intestinal helminth antigens are inducers of type 2 responses and can elicit regulatory immune responses, resulting in dampened inflammation. Several platyhelminth proteins with anti-inflammatory activity have been reported. We have identified, cloned and expressed the Taenia solium calreticulin (rTsCRT) and shown that it predominantly induces a type 2 response characterized by IgG1, IL-4 and IL-5 production in mice. Here, we report the rTsCRT anti-inflammatory activity in a well-known experimental colitis murine model...

Brucella canis infection is an important cause of late-term abortion in pregnant bitches. The pathophysiological mechanisms leading to B. canis-induced abortion are unknown, but heavily infected trophoblasts are consistently observed. As trophoblasts responses to other pathogens contribute to placental inflammation leading to abortion, the aim of the present study was to characterize the cytokine response of canine trophoblasts to B. canis infection. To achieve this, trophoblasts isolated from term placenta of healthy female dogs were infected with B...

PURPOSE: Acute pulmonary embolism (PE), frequently seen in the emergency department (ED), is a leading cause of cardiovascular morbidity and mortality. The delta neutrophil index (DNI) reflects the fraction of circulating immature granulocytes as a component of the systemic inflammatory response syndrome criteria. The pathogenesis of acute PE is significantly associated with inflammation. The aim of the study was to investigate the clinical usefulness of the DNI as a marker of severity in patients with acute PE admitted to the ED...

BACKGROUND: Cell-assisted lipotransfer (CAL) is a process in which fat grafting is supplemented with autologous adipose-derived stromal cells (ASCs). Since the efficacy of the technique was demonstrated, studies have focused on the mechanism by which CAL enhances the rate of graft survival. However, the microenvironmental changes in donor and recipient tissue associated with CAL remain unclear. METHODS: We introduced an animal model of CAL using two different transgenic reporter mice...

PURPOSE OF REVIEW: Severe asthma is a heterogeneous disease that can be classified into phenotypes and endotypes based upon clinical or biological characteristics. Interleukin (IL)-4 and IL-13 play a key role in type 2 (T2) asthma. This article reviews the signaling pathway of IL-4 and IL-13 and highlights its targeted therapy in severe asthma. RECENT FINDINGS: Several clinical trials of biologics targeting the IL-4/IL-13 pathway have recently been completed. In patients with severe, uncontrolled asthma, targeting IL-13 alone with biologics including lebrikizumab and tralokinumab has not shown consistent reduction in asthma exacerbations...

PURPOSE OF REVIEW: To provide an updated perspective of how nutritional screening and assessment in older persons should be performed and reasonably implemented in the near future. RECENT FINDINGS: Although nutritional screening and assessment should be fast and easy procedures, there is increasing evidence that more time should be dedicated to them. This is probably an answer to the claim to a medicine being more preventive than curative. Increasing interest is currently given to healthy aging and nutritional status is more likely to be addressed for its implications on functional status and disability...
