Streptococcus suis is a major pig pathogen as well as an emerging zoonotic pathogen. In a previous study (Zaccaria et al. Plos One DOI: 10.1371/journal.pone.0099394) we identified the natural pheromone-induced competence system of S. suis. To identify the mechanisms enabling competence, gene expression analysis of bacteria induced or not for competence, and in presence or absence of exogenous ...

The aim of this study was to investigate the effects of three Lactobacillus plantarum strains on in-vivo small intestinal barrier function and gene transcription in human subjects. The strains were selected for their differential effects on TLR signalling and tight junction protein rearrangement, which may lead to beneficial effects in a stressed human gut mucosa. Ten healthy volunteers partic ...

Mice have their lowest (basal) metabolic rate when housed at thermoneutrality, which starts above 29 degrees C. Although they eat less, and thus reduce their energy intake, their energy balance remains positive leading to an increased adiposity, especially when fed a high fat diet. However, almost all metabolic mouse studies are performed at standard room temperatures ranging between 20 and 22 ...

Metabolic dysfunction of white adipose tissue (WAT) is considered to be underlying the comorbidities in obesity, including insulin resistance and tissue inflammation. Moreover, due to the expansion of WAT, local tissue hypoxia has been reported. Whether local tissue hypoxia underlies the metabolic de-arrangements and is the first step in initiation inflammation is questioned here. Desferrioxam ...

ANGPTL4 regulates plasma triglyceride levels by inhibiting lipoprotein lipase. Inactivation of ANGPTL4 decreases plasma triglycerides and reduces risk of coronary artery disease. Unfortunately, targeting ANGPTL4 for the therapeutic management of dyslipidemia and atherosclerosis is hampered by the observation that mice and monkeys in which ANGPTL4 is inactivated exhibit lipid accumulation in me ...

Obesity induces macrophages to drive inflammation in adipose tissue, a crucial step towards the development of type 2 diabetes. The tricarboxylic acid (TCA) cycle intermediate succinate is released from cells under metabolic stress and has recently emerged as a metabolic signal induced by proinflammatory stimuli. We therefore investigated whether succinate receptor 1 (SUCNR1) could play a role ...

1. The decline of managed honeybees and the rapid expansion of mass-flowering crops increase the risk of pollination limitation in crops and raise questions about novel management approaches for wild pollinators in agroecosystems. Adding artificial nesting sites, such as trap nests, can promote cavity-nesting bees in agroecosystems, but effectiveness could be limited by the availability of flo ...

We investigated the global phylogeography of the brown rat (Rattus norvegicus) to understand routes of range expansion and population structure.
