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.

2-Amino-4-oxo-6-(1,2,3-trihydroxypropyl)-diquinoid-7,8-dihydroxypterin is a pterin derivative. Pterin is a heterocyclic compound composed of a pyrazine ring and a pyrimidine ring with Several tautomers; the pyrimidine ring has a carbonyl oxygen and an amino group. As a group, pterins are compounds that are derivatives of 2-amino-4-oxopteridine, with additional functional groups attached to the pyrazine ring. Pterins were first discovered in the pigments of butterfly wings and perform many roles in coloration in the biological world. Pterins also function as cofactors in enzyme catalysis (Wikipedia). Some pterin derivatives (biopterin, 6-formylpterin, 6-carboxypterin) accumulate in the skin of patients affected by vitiligo, a depigmentation disorder, where the protection against UV radiation fails due to the lack of melanin. Pterins participate in biologically important photosensitization processes; for example, pterins act as sensitizers in photochemical reactions that induce DNA damage4,5 and are able to generate singlet molecular oxygen6 and other reactive oxygen species (PMID: 19199487). 2-Amino-4-oxo-6-(1,2,3-trihydroxypropyl)-diquinoid-7,8-dihydroxypterin is a pterin derivative.
