About the Project

Several viruses require interaction with lysosomal proteins or autophagosomes in order to either facilitate infection of the host cell or ensure maturation and release. Lysosomal dysfunction most often manifests in organisms as either neurodegeneration or neurological decline that is almost always associated with impaired autophagy and clearance of damaged cellular organelles. Perhaps it is therefore unsurprising that consequences of viral infection often include prolonged hallmarks of neurological impairment that is sustained after the infection has been cleared. These include; the recent discovery that 1 in 3 Covid-19 patients manifest with neurological symptoms, HIV is associated with dementia, chicken pox in adults can subsequently cause long term peripheral nerve pain, polio virus impairs motor neuron function and cytomegalovirus is the most common viral cause of developmental neurological impairment. In all cases these viruses induce lysosomal or autophagosome-lysosome impairment, but the mechanisms underlying these cellular changes remain unclear.

The first aim of this project is to utilise our expertise in lysosomal cell biology to explore and identify lysosomal targets that underpin viral entry/egress and that induce cellular dysfunction in human iPSC derived neuronal models. The second aim is to identify viral effectors of lysosomal dysfunction and determine their impact on iPSC neuron function post-infection. The final aim is to utilise high throughput screening approaches to identify and develop small molecule candidates to restore cellular function in iPSC neurons post virus infection.
