Redox regulation plays a central role in signal transduction processes operating in the brain. Aberrant redox signaling is a hallmark of several neurodegenerative diseases such as Alzheimer’s disease, Huntington’s disease, Parkinson’s disease, Amyotrophic Lateral Sclerosis and various Ataxias. It...
Research in my laboratory is focused on understanding the molecular mechanisms of multi-subunit assemblies involved in synaptic communication. We are particularly interested in elucidating the structural thermodynamics that govern subunit assembly, ligand binding, and allosteric control of neurotransmitter receptors....
We are interested in the structure and function of the Golgi complex, a ubiquitous eukaryotic organelle that plays a central role in post-translational processing and sorting of newly synthesized proteins and lipids in the secretory pathway. The Golgi complex...
My laboratory has taken a multidisciplinary approach to understand the cellular and molecular mechanisms of different types of somatosensations including pain and itch, which are initiated and mediated by primary sensory neurons in dorsal root ganglia (DRG). We identified...
Our laboratory’s research focuses on understanding (1) how cells measure levels of available nutrients and (2) how cells adapt to changes in nutrient supply to control metabolic homeostasis. Our studies have primarily centered on changes in cholesterol and oxygen...
Neurotransmitter receptors mediate signal transduction at the postsynaptic membrane of synaptic connections between neurons in the nervous system. We have been studying the molecular mechanisms in the regulation of neurotransmitter receptor function. Recently we have focused on glutamate receptors,...
Mechanisms of gradient sensing and chemotaxis are conserved in mammalian leukocytes and Dictyostelium amoebae. Both cells use G protein linked signaling pathways. PH domains specific for PtdIns(3,4)P2 and PtdIns(3,4,5)P3 bind to the membrane at the leading edge of the...
Research Focus Our research focuses on “synthetic cell biology” to dissect and reconstitute intricate signaling networks. In particular, we investigate positive-feedback mechanisms underlying the initiation of neutrophil chemotaxis (known as a symmetry breaking process), as well as spatio-temporally dynamic...
Our research is focused on understanding how neuronal connectivity is established during development. Our work investigates the function of extrinsic guidance cues and their receptors on axonal guidance, dendritic morphology, and synapse formation and function. For several years we...
