Project Outline
Background:
Lysosomal dysfunction is a shared, early hallmark of many neurodegenerative diseases. This project integrates experimental and computational approaches to model lysosomal spatial dynamics in Amyotrophic Lateral Sclerosis (ALS) as a model for neurodegeneration. It aims to uncover important lysosomal morphological fingerprints & predict impairments driving disease pathology.
Aims & Objectives:
A. Experimental characterisation of lysosomal dynamics in neurons.
-Establish a quantitative baseline for lysosomal dynamics in healthy cells.
-Observe & quantify changes in lysosomal dynamics due to ALS-gene mutations.
B. Develop a predictive mathematical model of lysosomal functioning.
-Build a computational model of lysosomal dynamics using quantitative experimental data.
-Use the model to predict contributions to lysosomal dysfunction.
-Generate testable hypotheses to guide future experiments.
C. Model and validate lysosomal-relevant interventions for neurodegeneration.
-Use the model to predict the effects of perturbations or genetic mutations on lysosomal function.
-Experimentally validate important model predictions through targeted in vitro assays.
Key Terms: Neurodegeneration; ageing; lysosomal dynamics; cell & molecular biology; CRISPR; microscopy; bioimage analysis; mathematics; in silico simulation; computational modelling; supervised machine learning.
Methodology: The project combines experimental biology with computational modelling. Using a suite of techniques, important aspects of lysosomal function will be assessed & quantified in neuronal-like cells with key ALS-gene mutations and patient iPSC lines. Quantitative data from these experiments will be used to build a mathematical model of lysosomal function to help predict contribution to pathology and support in silico simulation of lysosomal-relevant interactions & interventions. The most significant model predictions will be experimentally validated.
