In sickness and in health: pivotal role of vitamin D.

Biochem Med (Zagreb) 2020 Jun;30(2):020501

Department of Clinical Chemistry, Sestre milosrdnice University Hospital Center, Zagreb, Croatia.

Within the last several years, frequency of vitamin D testing has multiplied substantially all over the world, since it has been shown to have an important role in many diseases and conditions. Even though liquid chromatography - tandem mass spectrometry (LC-MS/MS) has been identified as "gold standard" method for vitamin D measurement, most laboratories still use immunochemistry methods. Besides analytical problems (hydrophobicity, low circulating concentrations, ability to bind to lipids, albumins and vitamin D binding protein, presence of multiple vitamin D metabolites and variable ratios of 25(OH)D and 25(OH)D in the blood), vitamin D shows great preanalytical variability, since its concentration is drastically influenced by seasonal changes, exposure to sun, type of clothes or sun block creams.

Etienne Pays

FEBS J 2020 Jun 12. Epub 2020 Jun 12.

Laboratory of Molecular Parasitology, IBMM, Université Libre de Bruxelles, Gosselies, Belgium.

The discovery that apolipoprotein L1 (APOL1) is the trypanolytic factor of human serum raised interest about the function of APOLs, especially following the unexpected finding that in addition to their protective action against sleeping sickness, APOL1 C-terminal variants also cause kidney disease. Based on the analysis of the structure and trypanolytic activity of APOL1, it was proposed that APOLs could function as ion channels of intracellular membranes and be involved in mechanisms triggering programmed cell death. In this review, the recent finding that APOL1 and APOL3 inversely control the synthesis of phosphatidylinositol-4-phosphate (PI(4)P) by the Golgi PI(4)-kinase IIIB (PI4KB) is commented. Read More

Preclinical evidence on the role of glucagon-like peptide-1 receptor (GLP-1r) agonists in the brain led to an increased interest in repurposing these compounds as a therapy for central nervous system (CNS) disorders and associated comorbidities. We aimed to investigate the neuroprotective effects of acute treatment with exendin (EX)-4, a GLP-1r agonist, in an animal model of inflammation. We evaluated the effect of different doses of EX-4 on inflammatory, neurotrophic, and oxidative stress parameters in the hippocampus and serum of lipopolysaccharide (LPS)-injected animals. Read More

Front Behav Neurosci 2020 5;14:10. Epub 2020 Feb 5.

Department of Evolutionary Biology and Environmental Studies, University of Zurich, Zurich, Switzerland.

Social interactions are critically important for survival and impact overall-health, but also impose costs on animals, such as exposure to contagious agents. The immune system can play a critical role in modulating social behavior when animals are sick, as has been demonstrated within the context of "sickness behaviors." Can immune molecules affect or be affected by social interactions even when animals are not sick, therefore serving a role in mediating pathogen exposure? We tested whether markers of immune function in both the blood and the brain are associated with gregariousness, quantified as number of animals interacted with per day. Read More

Beta-lactam allergy in the paediatric population.

Paediatr Child Health 2020 Feb 6;25(1):62-63. Epub 2020 Feb 6.

Canadian Paediatric Society, Allergy Section, Ottawa, Ontario.

Beta-lactam allergy is commonly diagnosed in paediatric patients, but over 90% of individuals reporting this allergy are able to tolerate the medications prescribed after evaluation by an allergist. Beta-lactam allergy labels are associated with negative clinical and administrative outcomes, including use of less desirable alternative antibiotics, longer hospitalizations, increasing antibiotic-resistant infections, and greater medical costs. Also, children with true IgE-mediated allergy to penicillin medications are often advised to avoid all beta-lactam antibiotics, including cephalosporins, which is likely unnecessary in greater than 97% of those reporting penicillin allergies.

Antibodies have provided invaluable treatment options for many diseases, with immunotherapy revolutionising the treatment of several inflammatory disorders including inflammatory bowel disease (IBD). Accumulating evidence suggests that IBD results from an inappropriate response to intestinal microbes and environmental factors in genetically susceptible individuals, with overactivity of the pro-inflammatory pathways. On a pathophysiological level, IBD is a complex disease with intestinal fibrosis, stenosis and an increased incidence of cancer observed in those whose disease is inadequately controlled over time.

Human antibodies neutralizing diphtheria toxin in vitro and in vivo.

Sci Rep 2020 01 17;10(1):571. Epub 2020 Jan 17.

Technische Universität Braunschweig, Institute for Biochemistry, Biotechnology and Bioinformatics, Department of Biotechnology, Braunschweig, Germany.

Diphtheria is an infectious disease caused by Corynebacterium diphtheriae. The bacterium primarily infects the throat and upper airways and the produced diphtheria toxin (DT), which binds to the elongation factor 2 and blocks protein synthesis, can spread through the bloodstream and affect organs, such as the heart and kidneys. For more than 125 years, the therapy against diphtheria has been based on polyclonal horse sera directed against DT (diphtheria antitoxin; DAT). Read More

Prenatal LPS induces sickness behaviour and decreases maternal and predatory behaviours after an LPS challenge.

Int J Neurosci 2020 Jan 9:1-13. Epub 2020 Jan 9.

Graduate Program in Environmental and Experimental Pathology, Graduate Program in Dentistry, Paulista University, São Paulo, SP, Brazil.

The influence of a challenge dose of lipopolysaccharide (LPS) on the behavioural selection between maternal (MB) and predatory behaviours (PB) of female rats prenatally treated with the same endotoxin or saline solution (F1 generation) were studied. Thus, in adult age, these female rats were mated and, at lactation days 5 or 6, the following groups were formed: (1) LPS + LPS group-female rats prenatally treated with LPS and received an LPS challenge dose; (2) S + LPS group-female rats prenatally treated with saline solution and received a challenge LPS dose (3) S + S group-females rats prenatally treated with saline which received a saline injection. MB, PB to cockroaches, exploratory behaviour, periaqueductal grey (PAG) expression of the astrocytic biomarker glial fibrillary acidic protein (GFAP), and corticosterone and TNF-alpha serum levels were evaluated.

Neuroinflammation induced by lipopolysaccharide leads to memory impairment and alterations in hippocampal leptin signaling.

Behav Brain Res 2020 Feb 14;379:112360. Epub 2019 Nov 14.

Departamento de Bioquímica, Instituto de Ciências Básicas da Saúde, Universidade Federal do Rio Grande do Sul, Porto Alegre, Brazil. Electronic address:

Peripheral inflammation promotes immune-to-brain communication, mediated by cytokines that affect brain activity. Lipopolysaccharide (LPS) has been widely used to mimic systemic inflammation, and the adipokine leptin, released in this condition, modulates hypothalamic leptin receptors (ObR), contributing to sickness behavior. In this study, we used the intracerebroventricular (ICV) route for LPS administration in an attempt to evaluate an acute and direct of this pathogen-associated molecular pattern on leptin-mediated signaling in the hippocampus, where ObR has been implicated in modulating cognitive response.
