Metabolic diseases such as obesity are characterized by a subclinical inflammatory state that contributes to the development of insulin resistance and atherosclerosis. Recent reports also indicate that (i) there are alterations of the intestinal microbiota in metabolic diseases and (ii) absorption of endogenous endotoxins (namely lipopolysaccharides, LPS) can occur, particularly during the digestion...
Endothelial insulin resistance is tightly associated with diabetic cardiovascular complication, and it is well known that inflammation plays an important role in the development of insulin resistance. Luteolin, a flavonoid abundant in some medical and eatable plants, is a potent inhibitor of inflammation. It is also reported that luteolin exhibited some chemoprotection capability to the endothelial...
Uncontrolled or sustained inflammation is the underlying cause of or actively contributes to the progression of many chronic pathologies such as atherosclerosis, arthritis, or neuroinflammatory diseases. Matricellular proteins of the CCN family (CYR61/CTGF/NOV) have emerged as localized multitasking signal integrators. These structurally conserved secreted proteins specifically interact with and signal...
Legume lectins, despite high sequence homology, express diverse biological activities that vary in potency and efficacy. In studies reported here, the mannose-specific lectin from Cymbosema roseum (CRLI), which binds N-glycoproteins, shows both pro-inflammatory effects when administered by local injection and anti-inflammatory effects when by systemic injection. Protein sequencing was obtained by...
Lectins are glycan-binding receptors that recognize glycan epitopes on foreign pathogens and in the host systems. They can be involved in functions that include innate immunity, development, immune regulation and homeostasis. Several lectins have been purified and characterized from fish species. In this work, using cation-exchange chromatography, a galactose-specific lectin belonging to the family...
