Labs

 Popko Lab

Dr. Popko lab aims to uncover fundamental aspects of myelinating glial cell development and the myelination process, as well as the detailed function of the myelin sheath.

The Popko laboratory has a long-standing interest in the myelin sheath. Myelin is the multilayered membrane structure that surrounds most axons of the central and peripheral nervous systems. This extension of the myelinating glial cells’ plasma membrane promotes the very rapid nerve conduction velocities that are required in higher vertebrates, and it provides critical trophic support to the axons. Myelin is produced by Schwann cells in the peripheral nervous system and by oligodendrocytes in the central nervous system.

Our research interests include studies designed to uncover fundamental aspects of myelinating glial cell development, the myelination process, as well as the detailed function of the myelin sheath. We also devote considerable effort to gaining a better understanding of the neurological disorders that disrupt the myelination process during development and the maintenance of the myelin sheath in adults. In addition, we are particularly interested in developing therapeutic approaches to protect the myelinating cells from cytotoxic insult and to enhance the remyelination of demyelinated axons.

 Elbaz Lab

Dr. Elbaz’s lab investigates the mechanisms that regulate myelin-forming cell development and function.

Research Description

Myelin is a multilayer lipid membrane structure that ensheaths and insulates axons, allowing for the efficient propagation of action potentials along axons. Myelin abnormalities are part of a wide range of neurological disorders, including Multiple Sclerosis, leukodystrophies and neurodegenerative disorders. Our efforts to understand the molecular control of myelin formation are crucial in order to intervene, and enhance, myelin formation, remyelination, and recovery.

Our research is dedicated to investigating the mechanisms that regulate myelin-forming cell development and function. Myelin is a multilayer lipid membrane structure that ensheaths and insulates axons, allowing for the efficient propagation of action potentials along axons. Myelin is formed by oligodendrocytes in the central nervous system (CNS), and by Schwann cells in the peripheral nervous system (PNS).

In the CNS, our research is focused on the transcriptional control of oligodendrocyte differentiation and CNS myelin formation. The transcriptional network that controls oligodendrocyte differentiation contains only a handful of transcription factors, many of which have been characterized in considerable detail by us and by others. Nevertheless, our understanding of this transcriptional network is still lacking. Our studies aim to fill this void and fully characterize this transcriptional network. Our main transcription factors of interest are zinc finger protein 24 (Zfp24) and Sp7. Our previous research has identified Zfp24 and Sp7 as transcription factors that are essential for CNS myelination. We are now looking at the upstream effectors and downstream targets of Zfp24, and we are characterizing the role of Sp7 in oligodendrocyte lineage cells. In order to study Zfp24 and Sp7, we are developing novel mice models that allow us to either ablate or activate these transcription factors in oligodendrocyte lineage cells. 

In the PNS, our research is focused on understanding the mechanisms involved in PNS injury, recovery, and remyelination. PNS injury is a critical health concern. Understanding the mechanisms that control the response of Schwann cells to PNS injury is necessary to lay the foundation for future therapies. In our first project, we are focused on the role of the WNT signaling pathway in remyelination of the PNS. In our second PNS project, we are characterizing the effect of PNS demyelination on the sensory neurons.
