These bioactive molecules play important roles in several physiological pathways including stress and pain response, appetite, and lifespan. Recently, we reported the crystal structure of human NAPE-PLD and discovered specific binding sites for the bile acid deoxycholic acid. In this study, we demonstrate that in the presence of this secondary bile acid, the stiffness of the protein measured by elastic neutron scattering increases, and NAPE-PLD is ∼7 times faster to catalyze the hydrolysis of the more unsaturated substrate N-arachidonyl-phosphatidylethanolamine, compared with N-palmitoyl- phosphatidylethanolamine. Chenodeoxycholic acid and glyco- or tauro-dihydroxy conjugates can also bind to NAPE-PLD and drive its activation. The only natural monohydroxy bile acid, lithocholic acid, shows an affinity of ∼20 μM and acts instead as a ≈ μ fi reversible inhibitor (IC50 68 M). -

Abstract: G-protein-coupled receptors (GPCRs) comprise a large protein superfamily divided into six classes, rhodopsin-like (A), secretin receptor family (B), metabotropic glutamate (C), fungal mating pheromone receptors (D), cyclic AMP receptors (E) and frizzled (F). Until recently, GPCRs signaling was thought to emanate exclusively from the plasma membrane as a response to extracellular stimuli but several studies have challenged this view demonstrating that GPCRs can be present in intracellular localizations, including in the nuclei. A renewed interest in GPCR receptors’ superfamily emerged and intensive research occurred over recent decades, particularly regarding class A GPCRs, but some class B and C have also been explored. Nuclear GPCRs proved to be functional and capable of triggering identical and/or distinct signaling pathways associated with their counterparts on the cell surface bringing new insights into the relevance of nuclear GPCRs and highlighting the Citation: Gonçalves-Monteiro, S.; nucleus as an autonomous signaling organelle (triggered by GPCRs). -

The effects of these endogenous modulators on pre- and post-synaptic processes are discussed. The contribution of purines to the processes of quantal and non- quantal secretion of acetylcholine into the synaptic cleft, as well as the influence of the postsynaptic effects of ATP and adenosine on the functioning of cholinergic receptors, are evaluated. As usual, the P2-receptor-mediated influence is minimal under physiological conditions, but it becomes very important in some pathophysiological situations such as hypothermia, stress, or ischemia. There are some data demonstrating the same in neuromuscular transmission. It is suggested that the role of endogenous purines is primarily to provide a safety factor for the efficiency of cholinergic neuromuscular transmission. -

Vitamin D Receptor Promotes Healthy Microbial Metabolites
www.nature.com/scientificreports OPEN Vitamin D receptor promotes healthy microbial metabolites and microbiome Ishita Chatterjee1, Rong Lu1, Yongguo Zhang1, Jilei Zhang1, Yang Dai 2, Yinglin Xia1 ✉ & Jun Sun 1 ✉ Microbiota derived metabolites act as chemical messengers that elicit a profound impact on host physiology. Vitamin D receptor (VDR) is a key genetic factor for shaping the host microbiome. However, it remains unclear how microbial metabolites are altered in the absence of VDR. We investigated metabolites from mice with tissue-specifc deletion of VDR in intestinal epithelial cells or myeloid cells. Conditional VDR deletion severely changed metabolites specifcally produced from carbohydrate, protein, lipid, and bile acid metabolism. Eighty-four out of 765 biochemicals were signifcantly altered due to the Vdr status, and 530 signifcant changes were due to the high-fat diet intervention. The impact of diet was more prominent due to loss of VDR as indicated by the diferences in metabolites generated from energy expenditure, tri-carboxylic acid cycle, tocopherol, polyamine metabolism, and bile acids. The efect of HFD was more pronounced in female mice after VDR deletion. Interestingly, the expression levels of farnesoid X receptor in liver and intestine were signifcantly increased after intestinal epithelial VDR deletion and were further increased by the high-fat diet. Our study highlights the gender diferences, tissue specifcity, and potential gut-liver-microbiome axis mediated by VDR that might trigger downstream metabolic disorders. Metabolites are the language between microbiome and host1. To understand how host factors modulate the microbiome and consequently alter molecular and physiological processes, we need to understand the metabo- lome — the collection of interacting metabolites from the microbiome and host. -

University of Vermont, USA Abstract The two DUOX enzymes were originally identified as participating in the production of hydrogen peroxide as a pre-requisite for thyroid hormone biosynthesis in the thyroid gland [6]. NOX enzymes function to catalyse the reduction of molecular oxygen to superoxide and various other reactive oxygen species (ROS). They are subunits of the NADPH oxidase complex.
