Rheumatoid arthritis (RA) patients have sleep problems, and inflammation influences sleep. We demonstrated that sleep quality improves during intensified treatment with methotrexate (MTX) or etanercept (ETA). Since the hypothalamic-pituitary-adrenal (HPA) axis is involved in sleep regulation, this study investigated the interrelation between sleep parameters, inflammation as objectified by C-reactive protein (CRP), and serum cortisol and adrenocorticotropic hormone (ACTH) levels. Thirty-one eligible patients (disease activity score, DAS28CRP ≥3...

Upregulation of interleukin 15 (IL-15) contributes directly i.a. to the development of inflammatory and autoimmune diseases. Selective blockade of IL-15 aimed to treat rheumatoid arthritis, psoriasis and other IL-15-related disorders has been recognized as an efficient therapeutic method. The aim of the study was to identify small molecules which would interact with IL-15 or its receptor IL-15Rα and inhibit the cytokine's activity. Based on the crystal structure of IL-15Rα·IL-15, we created pharmacophore models to screen the ZINC database of chemical compounds for potential IL-15 and IL-15Rα inhibitors...

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is characterised by airflow obstruction due to an abnormal inflammatory response of the lungs to noxious particles or gases, for example, cigarette smoke. The pattern of care for people with moderate to very severe COPD often involves regular lengthy hospital admissions, which result in high healthcare costs and an undesirable effect on quality of life. Research over the past decade has focused on innovative methods for developing enabling and assistive technologies that facilitate patient self-management...

Lifestyle factors, such as food choices and exposure to chemicals, can alter DNA methylation and lead to changes in gene activity. Two such exposures with pharmacologically active components are coffee and tea consumption. Both coffee and tea has been suggested to play an important role in modulating disease-risk in humans by suppressing tumour progression, decreasing inflammation and influencing estrogen metabolism. These mechanisms may be mediated by changes in DNA methylation.To investigate if DNA methylation in blood is associated with coffee and tea consumption we performed a genome-wide DNA methylation study for coffee and tea consumption in four European cohorts (N = 3,096)...

Sherman A James
John Cassel's 1976 paper "The Contribution of the Social Environment to Host Resistance" (Am J Epidemiol. 1976;104(2):107-123) is widely regarded as a classic in epidemiology. He makes the compelling argument that the quality of a person's social relationships, that is, the degree to which her relationships are more stressful than supportive (or vice versa) influences her susceptibility to disease independent of genetic endowment, diet, physical activity, etc. Cassel's provocative thesis was anchored in a cogent synthesis of findings from animal experiments and observational studies on diverse human populations...

Background: Large cell neuroendocrine carcinoma of the lung (LCNEC) is a rare disease with poor prognosis and limited treatment options. Neuroendocrine tumors frequently show overactivation of the mTOR pathway. Based on the good activity of the mTOR inhibitor everolimus in different types of neuroendocrine tumors and the results of a previous phase I trial we evaluated the efficacy and safety of everolimus in combination with carboplatin and paclitaxel as upfront treatment for patients with advanced LCNEC...

Chronic idiopathic neutropenia (CIN) is an acquired disorder of granulopoiesis characterized by female predominance and mostly uncomplicated course. Crucial to CIN pathophysiology is the presence of activated T lymphocytes with myelosuppressive properties in both peripheral blood (PB) and bone marrow (BM). We systematically profiled the T cell receptor beta chain (TRB) gene repertoire in CD8(+) cells of 34 CIN patients through subcloning/Sanger sequencing analysis of TRBV-TRBD-TRBJ gene rearrangements. Remarkable repertoire skewing and oligoclonality were observed, along with shared clonotypes between different patients, alluding to antigen selection...

The Pti1 kinase was identified from a reverse genetic screen as contributing to pattern-triggered immunity (PTI) against Pseudomonas syringae pv. tomato (Pst). This was unexpected because Pti1 was originally identified as an interactor of the Pto kinase and was implicated in effector-triggered immunity. The tomato genome has two Pti1 genes, referred to as Pti1a and Pti1b. A hairpin-Pti1 (hpPti1) construct was developed and used to generate two independent stable transgenic tomato lines, which had reduced transcript abundance of both genes...

Chemical inhibition of epigenetic regulatory proteins BrdT and Brd4 is emerging as a promising therapeutic strategy in contraception, cancer, and heart disease. We report an easily synthesized dihydropyridopyrmidine pan-BET inhibitor scaffold, which was uncovered via a virtual screen followed by testing in a fluorescence anisotropy assay. Dihydropyridpyimidine 3 was subjected to further characterization and is highly selective for the BET family of bromodomains. Structure-activity relationship data and ligand deconstruction highlight the importance of the substitution of the uracil moiety for potency and selectivity...
