Engel's lab

Research Laboratory

We are an interdisciplinary Research Laboratory based in the Ben Gurion University of the Negev, Beer-Sheva, Israel. In collaboration with other laboratories at the BGU and from outside, we investigate novel concepts that underlie the complexities of neurodegenerative diseases.

Our Current Focus


Aerobic metabolism as driving force of CNS evolution and its susceptibility to neurodegenerative diseases

Despite different phenotypic manifestations, there are similarities in the molecular basis of major neurodegenerative diseases (NDs). CNS has evolved to be robust against the hazard of reactive oxygen species (ROS), a common perturbation aerobic organisms are confronted with. The trade-off of robustness is system’s fragility against rare and unexpected perturbations. Identifying the points of CNS fragility is key for understanding etiology of NDs. We postulated that the 'primate differential redoxome' (PDR), an assembly of proteins that contain cysteine residues (redox switches) present only in the primate orthologues of mammals, is likely to associate with an added level of regulatory functionalities, which enhanced CNS robustness against ROS and facilitated evolution. The PDR contains multiple deterministic and susceptibility factors of major NDs, which cluster to form coordinated redox networks regulating various cellular processes.
We employ a variety of experimental approaches, including cysteine redox proteomics and bioinformatics tools to corroborate the involvement of the PDR in the pathogenesis of major ND, such as Alzheimer’s, Parkinson’s and Huntington's diseases The goal is to identify the major points of CNS fragility, which is key for the development of mechanism-based therapeutics.

Targeting the pathogenic epitope of misfolded SOD1 to treat/prevent ALS

Amyotrophic lateral sclerosis (ALS) – is a neurodegenerative disease characterized by a gradual degeneration and death of motor neurons (MNs). A prominent ALS pathogenic protein is a ubiquitous enzyme superoxide dismutase 1 (SOD1), which is responsible for a significant fraction of familial and probably some sporadic cases. In ALS, SOD1 undergoes a noxious structural transformation, so-called misfolding, as a result of mutation or environmental stress, such as oxidative stress, rendering SOD1 neurotoxic. We have identified a pathogenic epitope exposed in misfolded SOD1, which appears to contribute to SOD1 neurotoxicity in ALS. Our strategy is to target this pathogenic SOD1 epitope, using a wide variety of pharmacological tools, in order to develop novel mechanism-based therapeutics to treat/prevent ALS.
