Journal ArticleDOI
D2 dopamine receptor gene (DRD2) Taq1 A polymorphism: reduced dopamine D2 receptor binding in the human striatum associated with the A1 allele.
John R. Thompson,N Thomas,Andrew B. Singleton,M.A. Piggott,S. Lloyd,Elaine K. Perry,Christopher Morris,Robert H. Perry,I. N. Ferrier,J.A. Court +9 more
TL;DR: A genetic predisposition to lower D2 receptor expression may increase susceptibility to neuroleptic medication or clinical symptoms that are associated with diseases involving dopaminergic pathology.
Journal ArticleDOI
Striatal dopaminergic markers in dementia with Lewy bodies, Alzheimer's and Parkinson's diseases: rostrocaudal distribution.
M.A. Piggott,Elizabeth F. Marshall,N Thomas,S. Lloyd,J.A. Court,Evelyn Jaros,David J. Burn,Mary Johnson,Robert H. Perry,Ian G. McKeith,Clive Ballard,Elaine K. Perry +11 more
TL;DR: Investigation of dopaminergic activities along the rostrocaudal striatal axis from a post-mortem series indicated compensatory increased turnover in Parkinson's disease, which was absent in DLB despite the loss of substantia nigra neurons, dopamine and uptake sites.
Journal ArticleDOI
Neuronal nicotinic receptors in dementia with Lewy bodies and schizophrenia: alpha-bungarotoxin and nicotine binding in the thalamus.
Jennifer A. Court,Dean Spurden,S. Lloyd,Ian G. McKeith,Clive Ballard,Nigel J. Cairns,Robert Kerwin,Robert H. Perry,Elaine K. Perry +8 more
TL;DR: It is concluded that widespread abnormalities of thalamic nicotine are not implicated in schizophrenia or DLB, but that reticular αBGT binding may be involved to a lesser and greater extent in the pathophysiology or psychopathology of both disorders.
Journal ArticleDOI
Nicotine binding in human striatum: elevation in schizophrenia and reductions in dementia with Lewy bodies, Parkinson’s disease and Alzheimer’s disease and in relation to neuroleptic medication
J.A. Court,M.A. Piggott,S. Lloyd,N. Cookson,Clive Ballard,Ian G. McKeith,Robert H. Perry,Elaine K. Perry +7 more
TL;DR: The changes observed in [3H]nicotine binding are likely to reflect the presence of these receptors on multiple sites within the striatum, which may be differentially modulated in the different diseases.
Journal ArticleDOI
Nicotinic and muscarinic cholinergic receptor binding in the human hippocampal formation during development and aging.
J.A. Court,S. Lloyd,Mary Ann Johnson,Martin Griffiths,Nigel J. M. Birdsall,M.A. Piggott,Arthur E. Oakley,Paul G. Ince,Elaine K. Perry,Robert H. Perry +9 more
TL;DR: Findings implicate mechanisms controlling the expression of nicotinic receptors to a greater extent than muscarinic receptors in postnatal development and aging in the human hippocampus.
