MRes - Brain Fog: How does Urban particulate Matter Pollution Impact on Brain Development?
Supervisors: Imelda McGonnell and Dr Claire Thornton
Department: Comparative Biomedical Sciences
Project Details:

Air pollution is the largest environmental cause of disease and premature death worldwide. Urban particulate matter (UPM) is of particular concern: levels have increased rapidly since the early 1990’s and, vulnerable individuals such as pregnant women and infants are the most likely to be affected through continued exposure to UPM. Early-life exposure to UPM is correlated with a wide range of neurodevelopmental impairments and life-long neuronal deficits although the precise mechanisms are not known. A better understanding of the interaction between UPM and brain development would support both preventative measures and therapeutic interventions in early life.
We have created a zebrafish embryo and larvae model of UPM exposure during brain development and have developed a combination of imaging and novel computation machine learning analysis tools to measure impact on the developing brain. We also have RNA seq data showing changes in expression of genes and pathways associated with a number of significant neurodevelopmental disorders.
This project will test the hypothesis that exposure to UPM during development results in abnormal brain architecture and altered gene expression in pathways that control this process. We also hypothesise that pharmacological manipulation of these pathways will result in reversal of the phenotype.
This project will involve a combination of imaging, computational analysis, molecular biology and bioinformatic skills and will be of interest to students with a developmental biology, neuroscience or broad biological sciences background.
