Crest Gold Award for SITraN Summer Student

SITraN Summer student Nemah Mabger, pictured, received the British Science Association's CREST Gold award (CREativity in Science and Technology) for her placement in the SITraN RNA research laboratory. The year 12 student from Tapton School in Sheffield was awarded a Nuffield scholarship to investigate TDP-43 proteinopathy in motor Nemah Magber.jpgneuron-like inducible cell models of motor neuron disease (MND) at SITraN under the supervision of Dr Guillaume Hautbergue and Jennifer Dodd for four weeks over the summer holidays. Supported by her teacher Dr Nick Harris, formerly a researcher at the University of Sheffield, Nemah is hoping to go on to study Medicine after completing her biology A-levels.

The Crest awards are granted by the British Science Association: "The Gold Awards allow the most able students to conduct real research. They are longer-term projects that require around 70 hours’ work, and are typically completed by 16-to-19-year-olds. By working towards a CREST Gold Award, students will develop and deliver largely self-directed projects. The aim is for students’ work to contribute something new to the scientific or technological community or to a particular field of study.  They are supported by an industry or higher education mentor, who can offer guidance and advice, and are required to prepare a final report and present the outcomes of their project to their CREST assessor."

Good neighbours turn bad: Helper cells in the brain could hold the clue to Motor Neuron Disease

A new study on motor neuron disease (MND) puts star-shaped helper cells in the brain, called astrocytes, in the spotlight. Researchers at the Sheffield Institute for Translational Neuroscience (SITraN) have revealed the full extent of astrocyte behaviour in a mouse model of MND from pre-symptomatic to late stages of the disease. Their findings suggest that astrocytes progressively lose the ability to support motor neurons as MND progresses which leads to the death of these specialised nerve cells that control our movements.

Co-lead of the study, Dr Janine Kirby, Senior Lecturer in Neurogenetics at the University of Sheffield, said:  “Overall, our data suggest that astrocytes react to disease by engaging damage limitation strategies including clearing debris and waste from the motor neurons and redistributing components such as cholesterol, which is crucial for nerve cell function. However, as the disease progresses, astrocytes lose their supportive functions and the ability to control their external environment which ultimately leads to the death of the motor neurons.”Astrocytes (red) and neurons (green) websize jpeg.jpg

Astrocytes are key players in the progression of MND and other neurodegenerative diseases such as Alzheimer’s disease. They have many important supportive functions and are critical for the proper functioning and survival of nerve cells. In order to provide the first detailed map of astrocyte behaviour throughout the disease course, researcher and study co-author Dr David Baker investigated differences in gene expression in astrocytes in a well-characterised mouse model of MND which carries the SOD1G93A mutation. The team confirmed their findings with further enzymatic essays and in vitro experiments.

One of the senior researchers of this study, Marie Curie Research Fellow Dr Laura Ferraiuolo and the team at SITraN have previously shown that astrocytes at the pre-symptomatic stage are known to lose some supportive functions to motor neurons seen in the decreased provision of growth factors as well as lactate needed to generate energy. The new data show that as the disease progresses and symptoms occur, SOD1 astrocytes transition into an activated state. The reactive astrocytes show an altered stress and immune responseAstrocyte schematic.png compared to their healthy counterparts. Waste processing and recycling is increased through the activation of lysosomal and phagocytic pathways, most likely to protect nerve cells from the accumulation of cell debris which can cause inflammation and lead to cell death (apoptosis). The late stage shows additional changes in cholesterol production and distribution which is also critical for neuron survival.

Clinician Scientist in Neurology and MND specialist Professor Dame Pam Shaw, Director of SITraN and co-lead of this study, said:  “Taken together, SOD1G93A astrocytes are characterized by a loss of supportive function towards motor neurons, as well as acquiring toxic properties during the disease course, and these factors in the neighbourhood of motor neurons compromise the health and survival of the nerve cells.  The next step will be to determine whether astrocyte behaviour can be modulated or even restored, and whether this is a means by which to slow down disease progression in MND.”

SITraN researchers join £1.3 million research collaboration to tackle devastating childhood disease Spinal Muscular Atrophy

UKSMARC-Logo-CMYK-for-website-page-2-599x243.jpgScientists from the Sheffield Institute for Translational Neuroscience have joined a £1.3 million research initiative to find effective treatments for Spinal Muscular Atrophy (SMA), the leading genetic cause of death in babies and toddlers. The new UK research consortium, led and funded by the SMA Trust, is the first of its kind to investigate the childhood form of Motor Neuron Disease (MND).

SMA is a debilitating disease caused by a faulty gene that affects nerve cells needed to control the muscles we use for moving, swallowing and breathing. One in 40 people are a carrier for the disease and in the most severe cases, approximately half of those affected, children rarely live beyond two years. The consortium, announced today (Tuesday 29 September 2015) during the first ever UK SMA Awareness Week, consists of world-class research and clinical experts based at the University of Sheffield’s Institute for Translational Neuroscience (SITraN) as well as Oxford, Edinburgh and London universities.

The main aims of the project are to further develop existing drug targets and identify new neuroprotective therapies to maintain function throughout the lives of people living with SMA and to identify improved ways of delivering treatments in order to maximise benefit throughout the body.

Professor Mimoun Azzouz

Professor Mimoun Azzouz who leads an extensive research programme on SMA at SITraN said: "This is a great initiative for SMA research in the UK. Significant progress has been made in the field, however the creation of this consortium will bring together excellent SMA experts to further our understanding of the disease and accelerate therapy development."

The SMA Trust has spent nearly £3 million since it was founded and now funds 75 per cent of all UK charity funded research into the condition.  It also helped create SMA Europe, an umbrella organisation that funds research projects all over Europe and the US, as well as promoting knowledge-sharing, collaboration and representation of a united ‘patient voice’ to pharmaceutical companies and regulatory authorities involved in clinical trials.

Joanna Mitchell, CEO of The SMA Trust said: “These are exciting times in SMA research and for the new UK research consortium. Recent years have seen rapid advances, with several companies now actively pursuing clinical trials for potential treatments. Whilst a cure for SMA remains the ultimate goal, we also recognise that, for the time being, ‘success’ is equally likely to come in the form of combinations of treatments that improve the quality of life of people living with SMA.”

The potential therapies for SMA currently in clinical trials are mainly concerned with increasing the amount of a crucial protein called Survival Motor Neuron (SMN), which is depleted in various degrees in people who have SMA. This offers great promise for treating SMA if such therapies can be delivered before motor neuron loss is established. However, it is believed that the principal effect of the SMN protein on the neuromuscular system occurs early in development, meaning that increasing the levels of SMN after development has occurred may not result in a substantial benefit on motor function for the majority of people living with SMA. This becomes an increasingly important issue as due to advances in therapies which increase SMN levels, more people will be living into adulthood with SMA in the future.

The Consortium, led by Professor Kevin Talbot at Oxford University, will seek to address this problem by looking more closely at the specific mechanisms of neuromuscular failure in the disease and investigating whether influencing other ‘non-SMN’ pathways will identify potential therapies which will benefit all individuals living with SMA by maintaining and enhancing the function of surviving motor neurons.

Listen to Prof Mimoun Azzouz talking about the new UK SMA research consortium on BBC Radio Sheffield live on 29th September with Howard Pressmann. The interview starts at 01:36:50.
