Signal Transduction and Metabolism

Group Leader: Esteban N. Gurzov, PhD.


The Signal Transduction and Metabolism laboratory focuses on the dysfunctional pathways in metabolic diseases. Great efforts have been made to understand how different cell types respond to the extracellular stimuli that control signalling pathways in the context of metabolic disorders such as obesity and diabetes, but the molecular mechanisms by which these pathologies occur remain poorly understood.


Group Leader, Dr Esteban Gurzov

Dr Esteban Gurzov has dedicated his scientific career to investigate the pathogenic mechanisms of obesity and diabetes and the discovery of novel therapeutics. After his productive postdoctoral period in Belgium, he moved to Australia to continue his training in molecular pathways of metabolic disorders. In 2017, he received a tenured Associate Researcher/Chercheur Qualifié position from the FRS-FNRS to head the Signal Transduction and Metabolism laboratory.

Research Interests: Molecular mechanisms of metabolic diseases

The focus of our research is to understand the signalling pathways responsible for the development of metabolic diseases. We study mechanisms of insulin-producing β-cell dysfunction and death in the pancreas and metabolic disorders in the liver, muscle and white adipocyte tissue. The strength of the laboratory is the combined use of molecular biology, animal models of diabetes and human samples. In addition, we are testing new molecules that can be used in pre-clinical studies to measure β-cell mass for the early diagnosis of the disease. This work is carried out at the ULB Center for Diabetes Research, which provides an ideal environment, with a strong focus on type 1 diabetes, as well as obesity and type 2 diabetes. A close collaboration exists between our Laboratory, the Laboratory of Experimental Gastroenterology and the Endocrine Division/Diabetes Unit of the Erasme Hospital (located in the same campus). This provides opportunities for interactions between researchers and clinicians and promotes translational research. We aim to make a difference to the millions of sufferers of metabolic diseases by providing insights into ways that the pathology can be detected and treated.
