Description

A more complete and holistic view on host–microbe interactions is needed to understand the physiological and cellular barriers that affect the efficacy of drug treatments and allow the discovery and development of new therapeutics. Here, we developed a multimodal imaging approach combining histopathology with mass spectrometry imaging (MSI) and same section imaging mass cytometry (IMC) to study the effects of Salmonella Typhimurium infection in the liver of a mouse model using the S. Typhimurium strains SL3261 and SL1344. This approach enables correlation of tissue morphology and specific cell phenotypes with molecular images of tissue metabolism. IMC revealed a marked increase in immune cell markers and localization in immune aggregates in infected tissues. A correlative computational method (network analysis) was deployed to find metabolic features associated with infection and revealed metabolic clusters of acetyl carnitines, as well as phosphatidylcholine and phosphatidylethanolamine plasmalogen species, which could be associated with pro-inflammatory immune cell types. By developing an IMC marker for the detection of Salmonella LPS, we were further able to identify and characterize those cell types which contained S. Typhimurium. [dataset] Nicole Strittmatter.

Description


DHAP(18:0) is the octadecanoyl derivative of Dihydroxyacetone phosphate. It is also known as an alkyl-DHAP. This compound is formed by octadecanoic acid reacting with DHAP. Alkyl-DHAPs are intermediates in the synthesis of ether phospholipids. The initial steps of ether phospholipid biosynthesis take place in peroxisomes. Alkyl-dihydroxyacetonephosphate synthase is the peroxisomal enzyme that actually introduces the ether linkage. Levels of Alkyl-DHAP have been found to be strongly reduced in human fibroblasts derived from Zellweger syndrome and rhizomelic chondrodysplasia punctata patients. Four other enzymes are known to be involved in the metabolism of acyl-DHAP and alkyl-DHAP. These include: acyl-DHAP/alkyl-DHAP oxidoreductase, DHAP acyltransferase, alkyl-DHAP phosphohydrolase, and a dinitrofluorobenzene-insensitive acyl-DHAP acylhydrolase. Dihydroxyacetone phosphate (DHAP) is a biochemical compound primarily involved in the glycolysis metabolic pathway. DHAP is also the product of the dehydrogenation of L-glycerol-3-phosphate which is part of the entry of glycerol (sourced from triglycerides) into the glycolytic pathway. Conversely, reduction of glycolysis-derived DHAP to L-glycerol-3-phosphate provides adipose cells with the activated glycerol backbone they require to synthesize new triglycerides. Both reactions are catalyzed by the enzyme glycerol 3-phosphate dehydrogenase with NAD+/NADH as cofactor. DHAP may be referred to as glycerone phosphate in older texts. 1-Octadecyl-glycerone-3-phosphate is an intermediate in Ether lipid metabolism. DHAP(18:0) or 1-Octadecanoyl-glycerone-3-phosphate is the precursor to 1-Octadecyl-glycerone-3-phosphate DHAP(18:0e) which is generated via alkylglycerone phosphate synthase (EC: 2.5.1.26). Ether lipids are lipids in which one or more of the carbon atoms on glycerol is bonded to an alkyl chain via an ether linkage, as opposed to the usual ester linkage. Ether lipids are called plasmalogens (1-O-1-alkenyl-2-acylglycerophospholipids) if these are glycerol-containing phospholipids with an unsaturated O-(1-alkenyl) (vinyl ether) group at the first position on the glycerol chain. Plasmalogens as well as some 1-O-alkyl lipids are ubiquitous and sometimes major parts of the cell membranes in mammals and anaerobic bacteria. In archaea, ether lipids are the major polar lipids in the cell envelope and their abundance is one of the major characteristics that separate this group of prokaryotes from the bacteria. In these cells, diphytanylglycerolipids or bipolar macrocyclic tetraethers can form covalently linked bilayers. [HMDB] DHAP(18:0) is the octadecanoyl derivative of dihydroxyacetone phosphate.
