SRY: A risk factor for Parkinson’s disease in males?

SRY: A risk factor for Parkinson’s disease in males? is a Research Project for the Brain and Gender Research Group, under the Centre for Endocrinology and Metabolism.

Project Leaders

lab-picParkinson’s disease (PD) is a debilitating neurodegenerative disorder, triggered by the death of dopamine neurons in the brain region known as the substantia nigra. Whilst the mechanisms underlying dopamine cell loss in PD, it is clear that males are more susceptible to PD than females.

We have identified that the Y-chromosome gene, SRY, directs a novel genetic mechanism of dopamine cell death in males (Czech et al., 2014). Understanding when and how SRY increases the vulnerability of male dopamine neurons to injury will help explain why males are more susceptible to the PD and to identify SRY as a novel target for neuroprotective therapy in male PD patients.

Approaches include neurosurgery, behavioural neuroscience, neuroanatomy and cellular and molecular biology.
