Atherosclerosis is a complex disease process in which genetic, lipid, cellular, and immunological factors combine to determine the location, severity, and timing of lesion development and clinical events. It has been demonstrated, however, that inflammation governed atherosclerosis during the course of development of atherosclerosis. It has also been demonstrated to be effective to decrease the cardiovascular events and improve the prognosis of atherosclerotic diseases by regulating inflammatory reaction (e.g., statins). However, endogenous mechanisms of limiting inflammation in atherosclerosis are still unclear. Recent studies showed that lipoxidase/leukotrienes (LOX/LTs) pathway played important role in the ignition and development of atherosclerosis, whereas resolvins (E-series resolvins and D-series resolvins) and protectins [protectin D1 (PD1) and neuroprotectin D1 (NPD1)], endogenous lipid-derived mediators, inhibited inflammation through pro-resolution and counter-modulating immune inflammation reaction in atherosclerosis. Hence, we hypothesize that increased endogenous lipid mediators mentioned above play a vital role in anti-atherosclerosis and plaque stabilization through pro-resolution and anti-inflammation by LOX/LTs pathway. In addition, we predict that the endogenous lipid mediators may be a new target for treatment of atherosclerotic diseases.

Background: Vitamin D (VD) deficiency and insulin resistance (IR) increase the risk of non-alcoholic fatty liver disease (NAFLD), but few studies have explored the potential mechanisms by which IR mediates the association between VD and the pathogenesis of NAFLD at the genetic level using publicly available databases.
Methods: This is a cross-sectional study, and we utilized the National Health and Nutrition Examination Survey (NHANES) dataset, as well as data from GSE200765 obtained from the Gene Expression Omnibus (GEO) website. A total of 723 individuals who had completed liver ultrasound examination and the detection of VD levels were included in the final analysis.
Lysophosphatidylinositol (LPI) is an endogenous signaling molecule for the GPR55 receptor. Previous studies have shown that arachidonoyl-lysophosphatidylinositol (LPI-20:4) produced an increase in the inflammatory mediators NLPR3 (inflammasome - 3 marker) and IL-1b in neurons from both rat dorsal root ganglion (DRG) and hippocampal cultures. Because LPI is comprised of a family of lipid structures that vary in fatty acyl composition, the current work examined neuroinflammatory responses to various LPI structures in DRG and hippocampal cultures as assessed by high content fluorescent imaging.

Sterol transport proteins mediate intracellular sterol transport, organelle contact sites, and lipid metabolism. Despite their importance, the similarities in their sterol-binding domains have made the identification of selective modulators difficult. Herein we report a combination of different compound library synthesis strategies to prepare a cholic acid-inspired compound collection for the identification of potent and selective inhibitors of sterol transport proteins.

Chronic kidney disease (CKD) is by far the most prevalent disease in the world and is now a major global public health problem because of the increase in diabetes, hypertension and obesity. Traditional biomarkers of kidney function lack sensitivity and specificity for early detection and monitoring of CKD progression, necessitating more sensitive biomarkers for early diagnostic intervention. Dyslipidemia is a hallmark of CKD.
