Although immunization with MHC class II-restricted ApoB peptides has been shown to be atheroprotective, the mechanism is unclear. Here, we investigated CD4(+) T cell populations in immunized atherosclerotic mice. Peptides (16-mers) from mouse ApoB, the core protein of low-density lipoprotein (LDL), were screened for binding to I-A(b) by computer prediction and confirmed by radiolabeled peptide competition. Three new peptides, P101 (FGKQGFFPDSVNKALY, 5.5 nM IC50), P102 (TLYALSHAVNSYFDVD, 6.8 nM), and P103 (LYYKEDKTSLSASAAS, 95 nM) were tested in an atherosclerosis model (Apoe(-/-) mice on western diet)...

PineXol, extracted from Korean red pine bark, has beneficial effects, such as antioxidant, anti3 inflammatory, and anti-lipogenic activities in vitro. We tested the hypothesis that PineXol supplementation could have anti-obesity effects on mice fed a high-fat diet (HFD). Four-week old male C57BL/6 mice were fed normal chow (18% kcal from fat) or HFD (60% kcal from fat). HFD-fed animals were also subjected to PineXol treatment at a dose of 10 or 50 mg/kg body weight (BW) (PX10 or PX50, respectively) body weight...

We compared 2 novel loop-mediated isothermal amplification (LAMP) assays that target either the 16S ribosomal RNA ( rrs) gene or the gene encoding a 32-kDa leptospiral lipoprotein ( lipL32) in order to assess the effect of the target on the accuracy of the LAMP assays. The most sensitive assay was the rrs assay with a limit of detection (LOD) of 1.2 × 10(1) genome equivalents per reaction. The novel lipL32 assay showed an LOD of 1.2 × 10(2) genome equivalents per reaction. Both assays showed adequate specificity when tested against a collection of bacteria commonly found in voided canine urine...

Colonization of the endometrium by pathogenic bacteria, ascending from the lower female reproductive tract (FRT), is associated with many gynecologic and obstetric health complications. To study these host-microbe interactions in vitro, we developed a human three-dimensional (3-D) endometrial epithelial cell (EEC) model using the HEC-1A cell line and rotating wall vessel (RWV) bioreactor technology. Our model, composed of 3-D EEC aggregates, recapitulates several functional/structural characteristics of human endometrial epithelial tissue including cell differentiation, junctional complexes/desmosomes, microvilli, membrane-associated mucins and Toll-like receptors (TLRs)...

We developed a regulatable gene expression system for Vibrio vulnificus, which contains a lacIq-pTrc cassette. Monomeric red fluorescence protein (mRFP) was used as a reporter to test this system. The results showed that this system tightly controlled the expression of mRFP without leaky expression and was suitable for the controlled expression of genes encoding recombinant proteins in V. vulnificus. To demonstrate the utility of this system, a dominant negative form of V. vulnificus VVMO6_RS04990, a homolog of Escherichia coli LolD that is essential in lipoprotein transport and membrane biogenesis, was inducibly expressed...

Ghrelin, a multifunctional gut-brain hormone, is involved in the regulation of gastric functions in mammals. This study aimed to determine whether ghrelin modulates digestive enzymes in goldfish (Carassius auratus). Immunofluorescence microscopy found colocalization of ghrelin, GHS-R1a and the digestive enzymes sucrase-isomaltase, aminopeptidase A, trypsin and lipoprotein lipase in intestinal and hepatopancreatic cells. In vitro ghrelin treatment in intestinal and hepatopancreas explant culture led to a concentration- and time-dependent modulation (mainly stimulatory) of most of the digestive enzymes tested...

BACKGROUND: Oxidized low-density lipoprotein (ox-LDL) is the most common inflammatory factor that mediates the activation and apoptosis of macrophages. Cyclophilin A (CyPA) is expressed following oxidative stress, hypoxia, and infection. However, the role of CyPA in the activation and apoptosis of macrophages is unclear. The aims of the study were to determine whether CyPA mediates the ox-LDL-induced activation and apoptosis in RAW264.7 cells and to analyze potential mechanisms. METHODS AND RESULTS: Through Western blot and ELISA test, the expression of CyPA induced by ox-LDL is time-dependent in RAW264...

High-fat (HF) diets typically promote diet-induced obesity (DIO) and metabolic dysfunction (i.e., insulin resistance, hypertriglyceridemia, and hepatic steatosis). Dysfunction of triacylglycerol (TAG) metabolism may contribute to the development of hepatic steatosis, via increased de novo lipogenesis or repackaging of circulating nonesterified fatty acids (NEFAs). Hepatic TAG production (HTP) rate can be assessed through injecting mice with nonionic detergents that inhibit tissue lipoprotein lipase. Potential confounding effects of detergent-based HTP tests (HTPTs) used in longitudinal studies-including the impact on food intake, energy balance, and weight gain-have not been reported...

REVIEW
David D Waters, S Matthijs Boekholdt
Since 2014, guidelines for the management of lipid disorders to reduce cardiovascular (CV) events have been updated in the United States, the United Kingdom, Europe, and Canada. Some of these guidelines are almost entirely evidence-based whereas others are a mix of evidence and expert opinion. Guidelines differ on such simple questions as to whether blood samples should be fasting or nonfasting, and whether low-density lipoprotein cholesterol (LDL-C) or another lipid parameter should be the primary focus of treatment...
