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


Phytanic acid (or 3,7,11,15-tetramethylhexadecanoic acid) is a 20-carbon branched-chain fatty acid that humans can obtain through the consumption of dairy products, ruminant animal fats, and certain fish. It is primarily formed by bacterial degradation of chlorophyll in the intestinal tract of ruminants. Unlike most fatty acids, phytanic acid cannot be metabolized by beta-oxidation (because of a methyl group in the beta position). Instead, it undergoes alpha-oxidation in the peroxisome, where it is converted into pristanic acid by the removal of one carbon. Pristanic acid can undergo several rounds of beta-oxidation in the peroxisome to form medium-chain fatty acids that can be converted into carbon dioxide and water in mitochondria. Refsum disease, an autosomal recessive neurological disorder caused by mutations in the PHYH gene, is characterized by having impaired alpha-oxidation activity. Individuals with Refsum disease accumulate large stores of phytanic acid in their blood and tissues. This frequently leads to peripheral polyneuropathy, cerebellar ataxia, retinitis pigmentosa, anosmia, and hearing loss. Therefore, chronically high levels of phytanic acid can be neurotoxic. Phytanic acids neurotoxicity appears to lie in its ability to initiate astrocyte/neural cell death by activating the mitochondrial route of apoptosis. In particular, phytanic acid can induce the substantial generation of reactive oxygen species in isolated mitochondria as well as in intact cells. It also induces the release of cytochrome c from mitochondria. A 20-carbon branched chain fatty acid, Phytanic acid is present in animal (primarily herbivores or omnivores) tissues where it may be derived from the chlorophyll in consumed plant material. Phytanic acid derives from the corresponding alcohol, phytol, and is ultimately oxidized into pristanic acid. In phytanic acid storage disease (Refsum disease) this lipid may comprise as much as 30\\% of the total fatty acids in plasma. These high levels in Refsum disease (a neurological disorder) are due to a phytanic acid alpha-hydroxylase deficiency.; A 20-carbon branched chain fatty acid. In phytanic acid storage disease (Refsum disease) this lipid may comprise as much as 30\\% of the total fatty acids of the plasma. This is due to a phytanic acid alpha-hydroxylase deficiency. [HMDB]
