  • Carolyn Machamer, Ph.D.

    The Machamer Lab is interested in the structure and function of the Golgi complex, an ubiquitous eukaryotic organelle that plays a central role in post-translational processing and sorting of newly synthesized proteins and lipids in the secretory pathway. One goal of our research is to understand the role of this structure in Golgi function by targeting and function of resident Golgi proteins. The other research interest in the lab is the assembly mechanism of coronaviruses, enveloped viruses that bud into Golgi compartments. We are addressing how coronaviruses target their envelope proteins to Golgi membranes, and how they interact with each other at the virus assembly site. We are also exploring how coronaviruses are exocytosed after they bud into the Golgi lumen. Our long-term goal is to understand the advantages of intracellular assembly for coronaviruses.

  • Haughey Lab: Neurodegenerative and Neuroinfectious Disease

    Dr. Haughey directs a disease-oriented research program that address questions in basic neurobiology, and clinical neurology. The primary research interests of the laboratory are:

    1. To identify biomarkers markers for neurodegenerative diseases including HIV-Associated Neurocognitive Disorders, Multiple Sclerosis, and Alzheimer’s disease. In these studies, blood and cerebral spinal fluid samples obtained from ongoing clinical studies are analyzed for metabolic profiles through a variety of biochemical, mass spectrometry and bioinformatic techniques. These biomarkers can then be used in the diagnosis of disease, as prognostic indicators to predict disease trajectory, or as surrogate markers to track the effectiveness of disease modifying interventions.
    2. To better understand how the lipid components of neuronal, and glial membranes interact with proteins to regulate signal transduction associated with differentiation, motility, inflammatory signaling, survival, and neuronal excitab...ility.
    3. To understand how extracellular vesicles (exosomes) released from brain resident cells regulate neuronal excitability, neural network activity, and peripheral immune responses to central nervous system damage and infections.
    4. To develop small molecule therapeutics that regulate lipid metabolism as a neuroprotective and restorative strategy for neurodegenerative conditions.

  • Kalina Hristova Lab

    The Kalina Hristova Lab investigates the structure and assembly of biological membranes. Our team conducts research on the structural and thermodynamic principles that enable membrane protein folding and signal transduction across biological membranes. Part of our work has involved developing new tools to study the structure of thermally disordered fluid membranes and the energetics of biomolecular interactions in biological membranes. Through our studies, we have established a better understanding of the physical principles behind complex biological processes and the mechanisms of disease development in humans.

  • William B. Guggino Lab

    Work in the William B. Guggino Lab focuses on the structure of the cystic fibrosis transmembrane conductance regulator (CFTR) and water channels; the molecular structure of transport proteins in epithelial cell membranes; and gene therapies to treat cystic fibrosis (CF) patients. We are also working to identify CF’s specific defect in chloride channel regulation. One recent study showed that insulin-like growth factor 1 (IGF-1) enhances the protein expression of CFTR.
