The Laboratory of Richard L. Huganir is interested in the mechanisms that regulate synaptic transmission and synaptic plasticity. Our general approach is to study molecular and cellular mechanisms that regulate neurotransmitter receptors and synapse function. We are currently focusing our efforts on the mechanisms that underlie the regulation of the glutamate receptors, the major excitatory neurotransmitter receptors in the brain.
Michael Wolfgang Laboratory
The Wolfgang Laboratory is interested in understanding the metabolic properties of neurons and glia at a mechanistic level in situ. Some of the most interesting, enigmatic and understudied cells in metabolic biochemistry are those of the nervous system. Defects in these pathways can lead to devastating neurological disease. Conversely, altering the metabolic properties of the nervous system can have surprisingly beneficial effects on the progression of some diseases. However, the mechanisms of these interactions are largely unknown.
We use biochemical and molecular genetic techniques to study the molecular mechanisms that the nervous system uses to sense and respond to metabolic cues. We seek to understand the neurometabolic regulation of behavior and physiology in obesity, diabetes and neurological disease.
Current areas of study include deconstructing neurometabolic pathways to understand the biochemistry of the nervous system and how these metabolic pathways impact animal beh...avior and physiology, metabolic heterogeneity and the evolution of metabolic adaptation. view more
The Mikhail Pletnikov Laboratory is interested in the neurobiology of neurodevelopmental diseases such as schizophrenia and autism. The major focus of our laboratory is to evaluate how adverse environmental factors and vulnerable genes interact to affect brain and behavior development. We address these experimental questions by using methods of cell and molecular biology, neuroimmunology, neurochemistry, psychopharmacology and developmental psychobiology. The current projects in our laboratory are: (1) Genetic risk factors in neuron-astrocyte interaction during neurodevelopment, (2) Gene-environment interplay in the pathogenesis of psychiatric conditions, and (3) The neuroimmune interactions in abnormal neurodevelopment
The Robinson Lab studies the way in which mechanical stress guide and direct the behavior of cells, including when they are part of tissues, organs and organ systems.
Research in the Nathaniel Comfort Lab looks at the history of biology. Areas of particular interest include heredity and health in 20th century America, genetics, molecular biology, biomedicine, the history of recent science, oral history and interviewing.
Nicholas Zachos Lab
Researchers in the Nicholas Zachos Lab work to understand variations in protein trafficking that occur during pathophysiological conditions that cause ion and water transport that result in diarrhea. We recently identified a clathrin-independent endocytic pathway responsible for elevated intracellular calcium-mediated inhibition of NHE3 activity in intestinal epithelial cells. We use advanced imaging techniques, including confocal and multi-photon microscopy, to characterize protein trafficking of intestinal transporters. We also perform functional assays using fluorescent probes (ratiometric and non-ratiometric) to measure ion transport in cell culture models, intact intestinal tissues and human small intestinal enteroids.
The O’Rourke Lab uses an integrated approach to study the biophysics and physiology of cardiac cells in normal and diseased states.
Research in our lab has incorporated mitochondrial energetics, Ca2+ dynamics, and electrophysiology to provide tools for studying how defective function of one component of the cell can lead to catastrophic effects on whole cell and whole organ function. By understanding the links between Ca2+, electrical excitability and energy production, we hope to understand the cellular basis of cardiac arrhythmias, ischemia-reperfusion injury, and sudden death.
We use state-of-the-art techniques, including single-channel and whole-cell patch clamp, microfluorimetry, conventional and two-photon fluorescence imaging, and molecular biology to study the structure and function of single proteins to the intact muscle. Experimental results are compared with simulations of computational models in order to understand the findings in the context of the system as a whole....
Ongoing studies in our lab are focused on identifying the specific molecular targets modified by oxidative or ischemic stress and how they affect mitochondrial and whole heart function.
The motivation for all of the work is to understand
• how the molecular details of the heart cell work together to maintain function and
• how the synchronization of the parts can go wrong
Rational strategies can then be devised to correct dysfunction during the progression of disease through a comprehensive understanding of basic mechanisms.

The Pedersen Laboratory is interested in cell energetics and the relationship of cell energetics to molecular medicine and disease. Both mitochondrial and glycolytic processes are being studied at the tissue, cell, and molecular level. Also, the relationship of these processes to cancer and heart disease, the two major causes of death in the U.S., is being studied with the objective of discovering and developing new therapies.
Specific projects in the laboratory that are currently under investigation include: 1) The structure, mechanism, and regulation of the mitochondrial ATP synthase/ATPase complex; 2) The molecular basis of cancer's most common phenotype, i.e., an elevated glucose metabolism; and 3) The regulation of heart function under normal and ischemic conditions as it relates to the mitochondrial ATP synthase/ATPase complex.
Our team consists of chemists, biologists and clinicians who work together in a highly collaborative environment.
Research in the Rong Li Lab aims to better understand the fundamental laws that regulate the behavior and interactions of cellular systems. Our team is currently examining how cells consolidate their damaged proteins and prevent them from spreading freely — work aimed at understanding how to better treat diseases such as Alzheimer’s and ALS. We are also applying insights gained through basic research to better understand diseases such as cancer and polycystic kidney disease.
The Sesaki Lab is interested in the molecular mechanisms and physiological roles of mitochondrial fusion. Mitochondria are highly dynamic and control their morphology by a balance of fusion and fission. The regulation of membrane fusion and fission generates a striking diversity of mitochondrial shapes, ranging from numerous small spheres in hepatocytes to long branched tubules in myotubes. In addition to shape and number, mitochondrial fusion is critical for normal organelle function.
