'''Colin Louis Masters''' {{small|MD}} {{post-nominals|country=AUS|FAA|AO}} (born 5 Feb 1947 in Perth, Western Australia) is an Australian neuropathologist who researches Alzheimer's disease and other neurodegenerative disorders. He is laureate professor of pathology at the University of Melbourne.<ref name="UM">{{cite web | title=Prof Colin Masters | website=The University of Melbourne | url=https://www.findanexpert.unimelb.edu.au/display/person13704 | access-date=29 September 2018}}</ref><ref name="Trove">{{cite web | title=Masters, Colin L.

==Career== Masters studied medicine at the University of Western Australia.<ref name="EOAS"/> He opted for an extra year of pre-medical studies in 1967, which he spent doing neuropathology research,<ref name="SW">{{cite web| title=Colin Masters Interview - Special Topic of Alzheimer's Disease| website=ScienceWatch.com| date=25 May 2011| url=http://archive.sciencewatch.com/ana/st/alz2/11maySTAlz2Mast/| access-date=1 October 2018}}</ref> and graduated M.B. B.S. in 1970. He completed his M.D. in medical neuropathology in 1977 after research fellowships at the University of Western Australia and Massachusetts General Hospital. After positions as visiting scientist at the National Institute of Neurological Disorders and Stroke and Humboldt fellow at Heidelberg University, he returned to Western Australia and Royal Perth Hospital in 1981 as a clinician-scientist. In 1989 he relocated to the University of Melbourne where he spent the rest of his career as consultant pathologist and professor of pathology, becoming laureate professor in 2002 and serving for six years as associate dean of research at the medical and dental school.<ref name="EOAS">{{cite web| title=Biographical entry - Encyclopedia of Australian Science| website=Masters, Colin Louis| url=http://www.eoas.info/biogs/P003963b.htm| first=Rosanne| last=Walker| date=26 March 2007| access-date=30 September 2018}}</ref>

==Scientific achievements== Masters and his erstwhile colleague from Heidelberg Konrad Beyreuther were the first to characterize the amyloid protein that forms the cerebral plaques observed in Alzheimer's disease (AD) and Down's Syndrome (DS, also known as trisomy 21).<ref name="pmid3159021">{{cite journal|vauthors=Masters CL, Simms G, Weinman NA, Multhaup G, McDonald BL, Beyreuther K| title=Amyloid plaque core protein in Alzheimer disease and Down syndrome| journal=Proc Natl Acad Sci U S A| year= 1985| volume=82| issue=12| pages=4245–9| pmid=3159021| pmc=397973| doi=10.1073/pnas.82.12.4245| doi-access=free}}</ref> Known as amyloid beta (Aβ), this peptide is derived from amyloid precursor protein (APP), which was subsequently mapped to the region of chromosome 21 that is altered in DS.<ref name="Tanzi">{{cite journal |vauthors=Tanzi RE, Bertram L| title=Twenty Years of the Alzheimer's Disease Amyloid Hypothesis: A Genetic Perspective | journal=Cell | publisher=Elsevier BV | volume=120 | issue=4 | year=2005 | issn=0092-8674 | doi=10.1016/j.cell.2005.02.008 | pages=545–555 | pmid=15734686| doi-access=free }}</ref> The notion that Aβ causes AD, called the amyloid hypothesis, gained force from genetic studies that traced familial forms of the disease to variations in the APP gene.<ref name="APPvar">{{cite journal | author=Goate A|display-authors=et al| title=Segregation of a missense mutation in the amyloid precursor protein gene with familial Alzheimer's disease | journal=Nature | publisher=Springer Nature | volume=349 | issue=6311 | year=1991 | issn=0028-0836 | doi=10.1038/349704a0 | pages=704–706 | pmid=1671712|s2cid=4336069}}</ref> Masters became a prominent proponent of the amyloid hypothesis, developing strategies for anti-Alzheimer's treatments that suppress the beta secretase and gamma secretase enzymes that cleave APP to form Aβ, or modify the interactions between metal ions and Aβ that are important for its toxic effects. Despite two decades of intensive research, however, these approaches have not yielded useful drugs.<ref name="Makin">{{cite journal | author=Makin S| title=The amyloid hypothesis on trial | journal=Nature | publisher=Springer Nature | volume=559 | issue=7715 | year=2018 | issn=0028-0836 | doi=10.1038/d41586-018-05719-4 | pages=S4–S7| pmid=30046080 | doi-access=free }}</ref>
