    Lysosomes are degradative organelles, whose function is critical for protecting long-lived cells such as neurons from the build up of misfolded proteins and damaged organelles. Altered lysosome function is associated with numerous neurodegenerative diseases such as Alzheimer's disease (AD), Parkinson's disease and hereditary spastic paraplegia (HSP). However, the molecular mechanisms underlying their involvement are not known. My previous work investigating the cell biology of amyloid plaques in AD led to the discovery of an unexpected heterogeneity of neuronal lysosomes: unlike lysosomes in neuronal cell bodies, those in neurites are deficient in luminal proteases and thus lack degradative capacity. Furthermore, I found that perturbing transport (and maturation) of the axonal pool specifically exacerbated Alzheimer's plaque pathology.

    My lab will now focus on understanding how these distinct lysosomal pools form, interact and function in the different parts of the neuron and how their dysfunction causes and/or exacerbates neurodegenerative diseases. Using a multidisciplinary approach (imaging, proteomics and CRISPR-Cas9 mediated perturbation in both primary mouse neurons and IPSC-derived neurons), the lab will identify the defining molecular composition of these distinct lysosomal populations, factors that uniquely (or differentially) regulate them and the molecular basis for their differential responses to stresses. We will also interrogate mechanisms underlying lysosome dysfunction in hereditary spastic paraplegia and Alzheimer’s Disease.
