Anthony David Smith FMedSci (born 16 September 1938) is a British biochemist and pharmacologist. Smith has spent his entire academic career in the University of Oxford.[1][2] His research focuses on biochemical changes with disease and prevention. This includes co-founding the Oxford Project to Investigate Memory and Ageing (OPTIMA[3]). He is one of the leaders of international research to find ways to prevent dementia.[4] He is also known for his work on the anatomical neuropharmacology of the basal ganglia.

Early life and education

[edit]

Smith was born in Kunming, China (missionary parents) and educated in Kingswood School, Bath. After 2 years as a technician at the MRC Radiobiological Research Unit, Harwell he became an undergraduate at Christ Church, University of Oxford where he graduated with a first-class honours degree in Biochemistry in 1963. He then joined the Department of Pharmacology[5] in Oxford and gained a D.Phil. in 1966. His doctoral research investigated the secretion of chemicals from the adrenal gland.[6]

Research and career

[edit]

After serving as Royal Society Stothert Research Fellow (1967–70), Smith was appointed University Lecturer in Pharmacology and Student (Fellow) of Christ Church in 1971. He was awarded the Gaddum Memorial Prize in 1978 for his discoveries on the release of noradrenaline through exocytosis.[7] In 1979 Smith introduced an antenatal acetylcholinesterase test for spina bifida in early pregnancy which has been used around the world.[8]

In 1984, David Smith was elected the fourth Statutory Chair of Pharmacology in the University of Oxford, and Head of Department until 2005.[9] In the same year, he was elected a Fellow of Lady Margaret Hall in Oxford where he remains an Emeritus Fellow.

David Smith co-founded the International Brain Research Organization's journal Neuroscience[10] and he served as Chief Editor from 1976 to 2001.

In 1985 Smith was appointed Founding Director of the MRC Anatomical Neuropharmacology Unit, Oxford which was associated with the Department of Pharmacology with associate director, Peter Somogyi FRS.[11]

In 1987 David Smith negotiated an agreement with E.R. Squibb & Sons Inc., which led to the donation of £20 million to the University of Oxford for a new building for the Department of Pharmacology and funding for research into brain diseases.[12]

In 1988 Smith co-founded the Oxford Project to Investigate Memory and Ageing (OPTIMA[13]), a longitudinal clinico-pathological study on more than 1,000 people to identify modifiable risk factors contributing to dementia, which continued until 2015.[14]

In 1998, OPTIMA discovered that elevated homocysteine and low levels of B vitamins are important risk factors for the development of Alzheimer's and vascular dementia.[15] This finding led to the VITACOG clinical trial to investigate whether lowering plasma homocysteine concentrations through high doses of supplementary B vitamins (folic acid, vitamins B6 and B12) over two years could slow the rate of losing brain tissue in elderly subjects with mild cognitive impairment, a precursor of dementia.[16] The results showed that the accelerated rate of brain atrophy in elderly with mild cognitive impairment can be significantly reduced in over half of cases through treatment with homocysteine-lowering B vitamins in subjects with a good omega-3 fatty acids status. In the same subjects, cognitive decline was slowed.

In 2000, Smith was appointed Deputy-Head (Vice-Dean) for 5 years to the newly established Medical Sciences Division[17] in the University of Oxford. In the same year he was elected Fellow of the Academy of Medical Sciences UK.[18]

From 1997 to 2002 Smith was the first Chair of the Scientific Advisory Board of Alzheimer's Research UK. In 2006, Alzheimer's Research UK appointed David Smith as their first Honorary Research Fellow. The David Smith Lectures in Anatomical Neuropharmacology[19] were established in 2008 as part of the 25th anniversary of the MRC Anatomical Neuropharmacology Unit.[20] A portrait of David Smith by Beth Marsden[21] (2005) hangs in the entrance lobby of the Department of Pharmacology.
