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.

Isovalerylcarnitine is the phenotypic abnormality in isovaleric acidemia (OMIM 243500) resulting from an accumulation of isovaleric acid, which is toxic to the central nervous system. Isovaleric acidemia is an autosomal recessive inborn error of leucine metabolism caused by a deficiency of the mitochondrial enzyme isovaleryl-CoA dehydrogenase (EC 1.3.99.10) resulting in the accumulation of derivatives of isovaleryl-CoA. It was the first organic acidemia recognized in humans and can cause significant morbidity and mortality. Early diagnosis and treatment with a protein restricted diet and supplementation with carnitine and glycine are effective in promoting normal development in severely affected individuals. An alternative pathway through glycine-N-acylase (EC 2.3.1.13) allows detoxification by producing isovalerylglycine, which is excreted. Thus, isovalerylcarnitine and isovalerylglycine are the hallmarks of this disorder in plasma and urine, respectively, and are elevated regardless of a patients metabolic condition (PMID: 16602101). Moreover, isovalerylcarnitine is found to be associated with celiac disease and very long-chain acyl-CoA dehydrogenase deficiency (VLCAD), which are also inborn errors of metabolism.

(PMID: 16602101) [HMDB] Isovalerylcarnitine is a product of the catabolism of L-leucine. Isovalerylcarnitine is also a selective and reversible calpain activator that induces apoptosis[1][2][3].
