Research

Research summary

Synapse development involves the adhesion of axons and dendrites and the recruitment of presynaptic vesicle release machinery in axons and neurotransmitter receptor machinery in dendrites. Trans-synaptic adhesion proteins, known as synapse organizers, coordinate these processes. These proteins play critical roles in synapse formation, maintenance, and synaptic plasticity. Mutations in genes encoding these proteins can disrupt synaptic function, increasing the risk for disorders like autism and schizophrenia. Dr. Siddiqui's research aims to:

  1. Understand the molecular mechanisms of synapse development and function.
  2. Investigate the mechanisms behind long-lasting changes in synaptic properties (plasticity).
  3. Explore how synapses are specified and organized in the mammalian brain.
  4. Discover regulatory mechanisms of synaptic function.

The Siddiqui lab's research will enhance our understanding of neuronal circuit formation and function, potentially leading to novel therapeutics targeting synapse organizers.

Biography

Brief bio

Dr. Tabrez Siddiqui is an associate professor at the University of Manitoba, where he is appointed in the Department of Physiology and Pathophysiology. He trained as a biophysicist and biochemist at the Max Planck Institute for Biophysical Chemistry in Germany. His postdoctoral work at the University of British Columbia focused on neuronal synapse development, contributing significantly to understanding glutamatergic synapses. In 2014, he joined the University of Manitoba. His research focuses on synaptic adhesion and scaffolding molecules. His lab employs various methods, including protein chemistry, glycobiology, molecular genetics, and animal behavior studies.
