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.

Aspartylglycosamine, also known as n4-(beta-N-acetyl-D-glucosaminyl)-L-asparagine or 1-beta-aspartyl-N-acetyl-D-glucosaminylamine, is a member of the class of compounds known as glycosylamines. Glycosylamines are compounds consisting of an amine with a beta-N-glycosidic bond to a carbohydrate, thus forming a cyclic hemiaminal ether bond (alpha-amino ether). Aspartylglycosamine is soluble (in water) and a moderately acidic compound (based on its pKa). Aspartylglycosamine can be found primarily in urine, as well as in human spleen tissue. Within the cell, aspartylglycosamine is primarily located in the cytoplasm. Moreover, aspartylglycosamine is found to be associated with aspartylglucosaminuria, which is an inborn error of metabolism. Large amount of aspartylglycosamine appears in patients with aspartylglycosaminuria corresponding to decreased activity of aspartylglycosamine amido hydrolase. Large amount of aspartylglycosamine appears in patients with aspartylglycosaminuria, which is a metabolic disorder associated with decreased activity of aspartylglycosamine amido hydrolase. [HMDB]
