Dementia & Neurodegeneration

Dementia & Neurodegeneration

The group members are engaged in investigating a wide spectrum of conditions and diseases (Alzheimer’s disease, Parkinson’s disease, Huntington’s disease, Frontotemporal dementia), with the focus on both neurones and glia, using diverse, but complementary approaches (imaging, molecular and cell biology techniques, electrophysiology, microbiological techniques).

Key Achievements

Group members regularly publish in peer-reviewed journals (please, see the link to UCLan’s repository (CLOK) below.

Dr Shalini Kanagasingam and Dr Sim Singhrao from the School of Dentistry were awarded an initial Oral and Dental Research Trust, Oral Health Innovation-ODRT OHI- (PreViser) Award of £4,907.00 in May 2018 and a follow up award of £5000 in April 2019 to study the Role of periodontal/endodontic pathogens in the development of the sporadic form of Alzheimer’s disease.

Dr Shalini Kanagasingam from the School of Dentistry was awarded the TC White ‘Young Researcher Award’ of £10,000 in June 2019 from the Royal College of Physicians and Surgeons of Glasgow. She will use the grant to further her work with Dr Sim Singhrao into the importance of endo-perio lesions in the development of tau-neurofibrillary tangles in Alzheimer’s Disease.

Activities of the Team

Prof. StJohn Crean has an extensive experience in Alzheimer’s disease research, particularly in relation to the role of oral bacteria.

Prof. Colin Davidson has an interest in neurodegeneration and has published in the fields of pre-clinical stroke research and drug abuse where methamphetamine has been shown to be neurotoxic, especially to the dopamine system. He uses fast cyclic voltammetry to measure neurotransmitters in brain tissue and rodent behavioural models to test novel therapeutics.

Dr. Sim K. Singhrao main interest lies in firmly establishing periodontal pathogens being a risk factor for the development of Alzheimer’s disease. The ultimate aim is to suggest a programme of health through scientific evidence by changing lifestyles and preventing hundreds of unnecessary sporadic dementia cases arising every year.

Dr Singhrao has been invited to share her subject knowledge by giving a platform presentation at the International Conference and Public Debate on Chronic Inflammatory Diseases, specifically ALZHEIMER’S DISEASE. It will be held at the Regent Convention centre on the 10-13th October, 2018, Switzerland.  The title of her presentation is ‘Prevention/delay onset of Alzheimer’s disease from an oral health/healthy living perspective’ and Sim will specifically be speaking about the role of gum disease causing bacteria as a risk for developing Alzheimer’s disease. The conference will also focus on Lime disease which can also leads to dementia and other neurological, psychiatric and chronic inflammatory disorders following chronic infections. The action plan is to face the challenge of behaviour in the demented and putative treatments/prevention/disease management, in the context of modifiable risk factors, during early life. The conference speakers include international scientists working on the infection model of Alzheimer’s disease in the presence of European Union politicians.

Dr Jane Alder has developed a novel human three-dimensional in vitro blood brain barrier (BBB) model from primary cells with realistic architecture and dynamic flow for the study of BBB dysfunction associated with neurodegenerative pathogenesis.

Dr Anthony Ashton’s group has characterized in depth the fact that synaptic vesicles can undergo both full fusion and kiss-and-run exocytosis and that vesicles can switch between these modes dependent upon the stimulation conditions and the precise pool of vesicles undergoing release. The switch is controlled by calcium levels and protein phosphorylation and we have established that two proteins – dynamin 1 and non-muscle myosin 2 – can regulate the kiss-and-run mode by closing the fusion pore. These results have been presented at several international meetings and is currently being submitted for publication. The relationships between these changes and Alzheimer’s disease (this has been referred to sometimes as type 4 diabetes) are being investigated. Current research on these modes have indicated that cAMP and PKA can also regulate these and the relationship between this and the role of calcium is being sought.

The group have been able to biochemically distinguish between the readily releasable and reserve pool/recycling pool of synaptic vesicles and this will enable the investigation of such pools in various models of disease including various neurodegenerative diseases and autism. Recently, they have investigated the silent pool (also called the reluctant or resting pool) of vesicles. These vesicles don’t normally contribute to release but certain conditions can induce these vesicles to undergo exocytosis. The Ashton group have been investigating the properties of silent pool of vesicles including whether specific calcium channels can regulate their release and whether certain protein kinases regulate their properties. The relationship between this pool and the phosphorylation state of synapsin 1 is being determined. Finally, an exciting project involves studying the role of alpha-synuclein in regulating this pool and the other pools of vesicles and whether this is regulated by phosphorylation of this protein. This is particularly exciting as aberrant phosphorylation of alpha-synuclein has been suggested to play a role in Parkinson’s disease as has aggregation of this protein. This research is important as the normal role of alpha-synuclein has not been fully elucidated.

Dr Chris Smith’s experience of in vivo microdialysis can be applied to disparate conditions from glioma to Alzheimer’s disease where the neurochemistry of the brain can be monitored in situ in the living organism as the disease progresses. In addition the technique can be used to determine the effect pharmacological agents would have on the release of neurotransmitters. A powerful aspect of in vivo pharmacology is combining microdialysis with behavioural studies to correlate the brain neurochemistry with behaviour, an ambition that is currently being worked towards as viral vectors currently being developed to induce mutations in neuronal signalling mechanisms will ultimately be applied to the freely moving organism.

Dr Donna Daly’s research aims to understand how the sensory nerves innervating the visceral organs such as the bowel and bladder detect normal mechanical and chemical stimuli, and how these signals are altered in neurodegenerative conditions such as ageing. She is also interested in the peripheral mechanisms of pain sensation and how this is also altered with natural ageing or due to disease.

Dr Jamal Nasir has a long standing interest in the genetics of neurodegenerative and neurodevelopmental disorders, including Huntington’s disease (HD). Jamal described the first published knock out mouse model for HD (Nasir et al., Cell. 1993).  More recently, he and his team have been exploring the genetics of neurodevelopmental disorders through investigating consanguineous populations and have undertaken functional studies of the relevant genes and their roles in various processes in the cell through external collaborations.  Dr Nasir has also been investigated the dopamine signalling pathway at the molecular level and identified novel dopamine receptor interacting proteins (DRIPs).  Finally, in collaboration with researchers at UCL, Dr Nasir is undertaking genomics and proteomics studies of stroke and various other conditions, including ALS, schizophrenia and Parkinson’s disease.

Dr Inmaculada Gonzalez: Neurotransmitter receptor insertion and removal to and from synapsis underlie many forms of experience-dependent plasticity including learning and memory. Understanding the processes that controls the surface expression, maintenance and dynamics of neurotransmitter receptors is key to establish the cellular and molecular basis of the excitatory transmission and synaptic plasticity in memory, cognition and normal brain function.

Dr Craig Bertram is engaged in the Parkinson’s disease research (specifically the pathogenetic mechanisms underlying the L-DOPA-induced dyskinesia), as well as the disturbance of glutamatergic signalling in dementia models (e.g frontotemporal dementia, FTD).
