Bart De Strooper is a Belgian molecular biologist and professor at KU Leuven and VIB, and at University College London. He was the founding director of the UK Dementia Research Institute.
His research concerns secretases: enzymes that cut the amyloid precursor protein (APP), producing the amyloid peptides that build up in the brain in Alzheimer’s disease.
In 1998 he showed in Nature that the protein presenilin is needed for this cleavage, a key discovery for understanding inherited Alzheimer’s.
He describes Alzheimer’s as a disease with a long ‘cellular phase’, in which brain cells such as microglia react for years before symptoms appear.
In 2018 he shared the Brain Prize, one of the most important awards in brain research, with John Hardy, Christian Haass and Michel Goedert.
For longevity, his work lays the biological groundwork for new treatments of one of the major diseases of ageing.
Takeaway: dementia develops over many years, so look after your blood pressure, exercise and social contacts from midlife onwards.
