Laboratory of Metabolism of Bioactive Lipids

Laboratory of Metabolism of Bioactive Lipids Metabolism of bioactive lipids

The Laboratory focuses on the analysis of lipid mediators (eicosanoids, docosanoids, endocannabinoids) using the UPLC-MS/MS method, in particular to identify the source of production of various mediators and their effect on metabolism and immune cells (i.e. adipocytes vs. macrophages). Currently, the lab is exploring new anti-diabetic lipids, fatty acid esters of hydroxy fatty acids and lipid-related metabolic pathways using stable isotopes.

We are always interested to hear from prospective candidates. Please submit a short personal statement detailing your research interests and qualifications, and a CV by email.

The Österreichische Gesellschaft für Molekulare Biowissenschaften und Biotechnologie (ÖGMBT) organizes virtual meeting BIOMOLECULES IN / FOR THE 21st CENTURY and series of Life Science Tuesdays online events / virtual meeting rooms. The first Tuesday, October 6, 2020 is focused on LIPIDS & METABOLISM and an overview of our FAHFA research will be presented.

OPEN PhD positions:

Targeted analysis of metabolic pathways - fluxomics by LC-MS/MS
New metabolic pathways involved in synthesis of anti-diabetic lipids

Branched fatty acid esters of hydroxy fatty acids (FAHFA)

White adipose tissue (WAT) is a complex endocrine organ and its low-grade inflammation in obesity contributes to the development of metabolic disorders. In 2014, a class of WAT-born lipid mediators - fatty acid esters of hydroxy fatty acids (FAHFA) was discovered. FAHFAs are endogenous lipids with anti-inflammatory and anti-diabetic properties, including the enhancement of glucose tolerance, and insulin and glucagon-like peptide 1 (GLP-1) secretion while reducing inflammatory responses [1-5].

Chemoinformatics resources

We run local instances of several services focused on Metabolomics, Lipidomics, Statistical analysis and Chemometrics. As the hardware resources are limited, these tools are available only within campus LAN. More

Omega-3 polyunsaturated fatty acids

Naturally occurring long-chain omega-3 PUFA, namely eicosapentaenoic acid (EPA; 20:5 ω-3), docosapentaenoic acid (DPA; 22:5 ω-3), and docosahexaenoic acid (DHA; 22:6 ω-3) exert multiple biological effects... More
