Background: We study the cellular and molecular mechanisms underlying neurodegenerative diseases, such as Parkinson’s disease (PD). Specifically, we are interested in understanding how the immune cells of the brain (microglia) are altered in PD and how those changes lead to neuronal death. My lab uses in vitro models of a genetic variant of PD to understand the role of inflammation and phagocytosis in the process of neurodegeneration. We use cellular, molecular, microscopy, and quantitative techniques to investigate the different environmental factors that can contribute to brain inflammation and neuronal distress. At some point, the combination of genetic and environmental insults reach a tipping point, leading to extensive phagocytosis and neurotoxicity of neurons in PD.
Brain-derived neurotrophic factor is a protein that is essential for neuronal health. This protein binds to trkB, a receptor found in the plasma membrane of neurons. These two proteins, and the intracellular signaling, are disrupted in many neurodegenerative diseases, including PD. Therefore, my lab also investigates how these proteins get disrupted in PD and their relevance to neuroinflammation. If we can understand how these proteins are disrupted in PD, we can identify potential therapeutic target in for neurodegenerative diseases.
