glycolipid/inflammation

The cell wall of mycobacteria is characterised by glycolipids composed of different classes of mycolic acids (MAs; alpha-, keto-, and methoxy-) and sugars (trehalose, glucose, and arabinose). Studies using mutant Mtb strains have shown that the structure of MAs influences the inflammatory potential

Structural studies of the major glycolipids produced by two Lactobacillus johnsonii (LJ) strains, LJ 151 isolated from intestinal tract of healthy mice and LJ 142 isolated from mice with experimentally induced inflammatory bowel disease (IBD), were performed. Two major glycolipids, GL1 and GL2, were

The involvement of the phenolic glycolipid from Mycobacterium leprae in cell-mediated immunity has been investigated in this study. The phenolic glycolipid itself does not appear to stimulate cell-mediated immunity directly, as shown by its failure to elicit a classical delayed-type hypersensitivity

Neuroinflammation is an early event during diabetic retinopathy (DR) that impacts the dynamics of microglia polarization. Gliosis is a hallmark of DR and we have reported the beneficial effects of 1R-DSO-ONJ, a member of the sp2-iminosugar glycolipid (sp2-IGL) family, in targeting microglia and

Glycolipid mimetics consisting of a bicyclic polyhydroxypiperidine-cyclic carbamate core and a pseudoanomeric hydrophobic tail, termed sp²-iminosugar glycolipids (sp²-IGLs), target microglia during neuroinflammatory processes. Here we have synthesized and investigated new

Immunomodulatory glycolipids, among which α-galactosylceramide (KRN7000) is an iconic example, have shown strong therapeutic potential in a variety of conditions ranging from cancer and infection to autoimmune or neurodegenerative diseases. A main difficulty for those channels is that they often

Mycobacterium bovis (BCG) was submitted to lipid extraction involving gentle and drastic procedures. Neutral lipids, glycolipids as well as phospholipids were detected in the diethyl ether extract, whereas the chloroform and chloroform-methanol extracts contained mainly phospholipids. Arabinose

Valpha14-expressing NKT (invNKT) cells are a population of non-conventional T lymphocytes (TL) that bridge mammalian innate and adaptive immunity. Their role in infectious diseases and inflammatory processes is still largely ununderstood. A previous report has shown that an acute granulomatous-like

We previously showed that formation of pulmonary granulomas in mice in response to a mycobacterial glycolipid, trehalose 6,6'-dimycolate (TDM) is due to the action of TNF-α and not of IFN-γ. However, the mechanisms of formation and maintenance of pulmonary granulomas are not yet clear. The purpose

Anemarrhena asphodeloides bunge is a traditional Chinese medicine and timosaponin BII is one of the most abundant and widely studied active ingredients in anemarrhena asphodeloides bunge. Related studies have shown that timosaponin BII has potential value for development and utilization. The

Lanceolitols A1-A7 (1-7) and B1-B7 (9-15), two series of new myo-inositol-derived glycolipid analogues, in which a sugar moiety is replaced by a fatty acid esterified myo-inositol moiety, were isolated from the leaves of Solanum lanceolatum. Their structures were elucidated on the basis of

Inhibition of phagosome maturation is an important hallmark of mycobacterial pathogenesis. A variety of genomic, transcriptomic and proteomic approaches have been used to pin down the molecule responsible for this pathogenic principle. We in this study characterize a glycolipid of Mycobacterium

1. The inflammatory properties of a glycolipid fraction isolated from human recovered Mycobacterium leprae were investigated. The inflammatory reaction induced in mouse lung by the inoculation of the glycolipid fraction adsorbed to charcoal particles was characterized by a large influx of

[Purpose] To investigate the effects of combined aerobic and resistance training on glycolipid metabolism and inflammation levels in type 2 diabetes mellitus patients. [Subjects and Methods] Forty-two diabetes patients were randomized to the conventional therapy group (n = 20) or intensive therapy

Since glycolipid biosynthesis is potentially involved in immunological and inflammatory responses, we tested the effect of a novel inhibitor of intracellular glycolipid biosynthesis N-(5-adamantane-1-yl-methoxy-pentyl)-deoxynojirimycin (AMP-DNM) in two hapten-induced colitis models: trinitrobenzene
