Research Overview

Spinal Muscular Atrophy

Systemic involvement in neurodegeneration, especially of the cardiovascular system

Effects of Hypoxia and ischaemia on the nervous system

Current Research

Spinal muscular Atrophy (SMA) is a childhood form of Motor Neurone Disease. It is caused by a defect in a gene which 1:35 of us carry. When two carriers come together there is a 1:4 chance of producing an affected child. SMA is the second most common genetic cause of infant death, affecting between 1:6-10,000 live births Worldwide. The most severely affected children will never sit unaided and will die before their second birthday. The disease is characterised by a loss of motor neurones and resultant muscle weakness and inability to carry out co-ordinated motor tasks including breathing. The genetic defect is well-characterised and attempts to replace or reduce the severe depletion of the key Survival of Motor Neurone (SMN) protein are ongoing. However, even when protein levels in motor neurones are increased and improvements in motor parameters are reported, survival is not increased. 

There is an increasing appreciation that this is not a classical motor neurone disease, but rather a systemic disease in which motor neurones are either most vulnerable or that defects in them are most clinically relevant. 

Our research has pioneered significant pre and early symptomatic defects in the cardiovascular system, where the heart, blood vessels and circulating cells are all defective in SMA. We are now particularly interested to determine how this impacts on SMA disease development and progression. This is particularly relevant in the new post- therapeutic landscape, as these were designed to target neuronal defects.

We are currently exploring the extent to which the non-neuronal pathologies described in animal models are also seen in human post-mortem material and are using cellular models to determine the vulnerabilities of SMA cells to hypoxic environments. These will help us to understand and develop novel combinatorial therapies to treat the entirety of SMA pathology in patients. 

Most recently, we are exploring similar non-motor pathologies in ALS/ MNDs.
