The potential of steroid hormones as protective factors following ischaemic stroke.
Cerebral ischaemic stroke, in the UK, is the 3rd leading cause of mortality, 1st leading cause of morbidity and estimated to cost the NHS £2.8 bn per annum in direct costs. There is a real need for basic research to identify potential neuroprotective strategies in order to determine whether clinical investigation is warranted. Steroid hormones, such as oestrogens and progesterone, have been shown to have neuroprotective properties following stroke and my research focuses on investigating the mechanisms of progesterone neuroprotection and assessing the translational potential of progesterone treatment.
In addition, steroid hormones are believed to have an influence on cognitive functioning. My research is aimed at investigating how oestrogens affect cognitive functions over the normal life span and during cognitive disorders including dementia of the Alzheimer's type.
Investigating inflammatory mediators of ischaemic damage to identify potential therapeutic targets.
Inflammation is key contributor to the damage that occurs following ischaemic stroke and the identification of the key mediators of this inflammatory response will help identify potential therapeutic targets. My lab investigates, in collaboration with stroke clinicians at the University of Nottingham, the molecular mechanisms that mediate the breakdown of the blood-brain barrier in order to identify potential treatment strategies. In addition, I am pursuing an interest in the role of prostaglandins following ischaemic stroke in collaboration with Dr Grubb (Department of Cell Physiology & Pharmacology).
