1. Metabolomic Reprogramming of C57BL/6-Macrophages during Early Infection with L. amazonensis
Maricruz Mamani-Huanca, Sandra Marcia Muxel, Stephanie Maia Acuña, Lucile Maria Floeter-Winter, Coral Barbas, Ángeles López-Gonzálvez Int J Mol Sci. 2021 Jun 26;22(13):6883. doi: 10.3390/ijms22136883.
Leishmania survival inside macrophages depends on factors that lead to the immune response evasion during the infection. In this context, the metabolic scenario of the host cell-parasite relationship can be crucial to understanding how this parasite can survive inside host cells due to the host's metabolic pathways reprogramming. In this work, we aimed to analyze metabolic networks of bone marrow-derived macrophages from C57BL/6 mice infected with Leishmania amazonensis wild type (La-WT) or arginase knocked out (La-arg-), using the untargeted Capillary Electrophoresis-Mass Spectrometry (CE-MS) approach to assess metabolomic profile. Macrophages showed specific changes in metabolite abundance upon Leishmania infection, as well as in the absence of parasite-arginase. The absence of L. amazonensis-arginase promoted the regulation of both host and parasite urea cycle, glycine and serine metabolism, ammonia recycling, metabolism of arginine, proline, aspartate, glutamate, spermidine, spermine, methylhistidine, and glutathione metabolism. The increased L-arginine, L-citrulline, L-glutamine, oxidized glutathione, S-adenosylmethionine, N-acetylspermidine, trypanothione disulfide, and trypanothione levels were observed in La-WT-infected C57BL/6-macrophage compared to uninfected. The absence of parasite arginase increased L-arginine, argininic acid, and citrulline levels and reduced ornithine, putrescine, S-adenosylmethionine, glutamic acid, proline, N-glutamyl-alanine, glutamyl-arginine, trypanothione disulfide, and trypanothione when compared to La-WT infected macrophage. Moreover, the absence of parasite arginase leads to an increase in NO production levels and a higher infectivity rate at 4 h of infection. The data presented here show a host-dependent regulation of metabolomic profiles of C57BL/6 macrophages compared to the previously observed BALB/c macrophages infected with L. amazonensis, an important fact due to the dual and contrasting macrophage phenotypes of those mice. In addition, the Leishmania-arginase showed interference with the urea cycle, glycine, and glutathione metabolism during host-pathogen interactions.
2. Associations of altered hepatic gene expression in American lifestyle-induced obesity syndrome diet-fed mice with metabolic changes during NAFLD development and progression

Non-alcoholic fatty liver disease (NAFLD) pathogenesis remains poorly understood due to the complex metabolic and inflammatory changes in the liver. This study aimed to elucidate hepatic events related to inflammation and lipid metabolism and their linkage with metabolic alterations during NAFLD in American lifestyle-induced obesity syndrome (ALIOS) diet-fed mice. 48 JaxC57BL/6J male mice were fed with ALIOS diet (n=24) or control chow diet (n=24) for 8, 12, and 16 weeks. At the end of each timepoint, 8 mice were sacrificed where plasma and liver were collected. Hepatic fat accumulation was followed using magnetic resonance imaging and confirmed with histology. Further, targeted gene expression and non-targeted metabolomics analysis were conducted. Our results showed higher hepatic steatosis, body weight, energy consumption, and liver mass in ALIOS diet-fed mice compared to control mice. ALIOS diet altered expression of genes related to inflammation (Tnfa and IL-6) and lipid metabolism (Cd36, Fasn, Scd1, Cpt1a, and Ppara). Metabolomics analysis indicated decrease of lipids containing polyunsaturated fatty acids such as LPE(20:5) and LPC(20:5) with increase of other lipid species such as LPI(16:0) and LPC(16:2) and peptides such as alanyl-phenylalanine and glutamyl-arginine. We further observed novel correlations between different metabolites including sphingolipid, lysophospholipids, peptides, and bile acid with inflammation, lipid uptake and synthesis. Together with the reduction of antioxidant metabolites and gut microbiota-derived metabolites contribute to NAFLD development and progression. The combination of non-targeted metabolomics with gene expression in future studies can further identify key metabolic routes during NAFLD which could be the targets of potential novel therapeutics.
3. The memory enhancing effect of the APP-derived tripeptide Ac-rER is mediated through CRMP2
Radmila Mileusnic, Steven P R Rose J Neurochem. 2011 Aug;118(4):616-25. doi: 10.1111/j.1471-4159.2011.07193.x. Epub 2011 Feb 24.
The diasteromeric (D/L) form of the acetylated tripeptide rER (NH2-D-arg-L-glu-D-arg-COOH), derived from the external domain of amyloid precursor protein, protects against amyloid-β induced memory loss for a passive avoidance task in young chicks and enhances retention for a weak version of the task when injected peripherally up to 12 h prior to training. The tripeptide readily crosses the blood-brain barrier, binds to receptor sites in the brain and is without adverse effects on general behaviour. The mechanisms of its action are unknown, as are its target molecules/pathways. Here, we report the binding partners for Ac-rER are collapsin response mediator protein 2 (CRMP2), syntaxin binding protein 1 and heat shock protein 70. Behavioural studies of the effects of Ac-rER on memory retention confirmed that the effect of Ac-rER is mediated via CRMP2, as anti-CRMP2 antibodies if injected intracranially 30 min pre-training, induced amnesia for the passive avoidance task. However, Ac-rER, if injected prior to the anti-CRMP2, rescues the memory deficits induced by anti-CRMP2 antibodies. As CRMP2 is placed at the junction of many different cellular processes during brain development and in adult neuronal plasticity as well as being implicated in Alzheimer's disease, this strengthens the claim that Ac-rER may be a potential therapeutic agent in Alzheimer's disease, although its precise mode of action remains to be elucidated.
