Neuroprotection in Rodent Stroke Models

Programme(s) to which this project applies:

☒ MPhil/PhD ☑ MRes[Med] ☒ URIS

Objective and Significance:

The overall objective is to define the neuroprotective mechanisms ofneuropeptide Y-Yl receptor inhibition or melatonin in in vivo or in vitro rodent stroke models.

The results may broaden our understanding of the pathophysiological mechanisms of ischaemic brain damage and lead to novel treatments of stroke in patients.

Research Plan and Methodology:

Studies will be performed in adult rats or mice. Endovascular middle cerebral artery occlusion (MCAO) will be used as the in vivo stroke model. Oxygen-glucose deprivation (OGD) will be used as the in vitro stroke model. Nitric oxide may be measured in some experiments. In addition to neuropeptide Y, its receptor analogs, or melatonin, other chemicals will be used to modulate the levels of some established mediators of ischemic damage such as nitric oxide, calcium, and glutamate. Results will indicate whether neuroprotection from neuropeptide Y-Y1 receptor inhibition or melatonin is mediated via any of the established mediators of ischemic damage.
