Alzheimer‘s disease (AD), which is defined by memory deficits and cognitive impairment, is the most common form of dementia in the elderly with more than 26 million people worldwide living with the disease. AD is characterized, among other pathological features by the accumulation of beta-amyloid peptides (A? peptides) in the brain. A? peptides are thought to contribute to synaptic dysfunction and neuro-inflammation in the brain and play a significant role in the blood brain barrier (BBB) dysfunction during the course of AD. At present, there are not proper human in vitro blood brain barrier models, which mimic physiological human conditions, and the effects of each A? fragment on the individual BBB cells as well as BBB integrity remains unknown.
<p>The main aim of this pilot project is to improve a novel human in vitro dynamic BBB model to examine the differential effects of specific Aβ peptide fragments (e.g., Aβ 1-40 and Aβ25-35) in both static and dynamic conditions. We will focus on the effect of each fragment over each cell type implicated in the BBB formation and transport. This will help us to design further experiments to study the role of BBB implication in AD in a more realistic way, which could lead to the development of new therapies for this devastating disease. The student will get training on cell culture, microfluidic system, immunohistochemistry, Western Blotting, and other relevant techniques. The student will participate to weekly lab meeting and journal club to share their work with the group. The student will have advantage in working in a multidisciplinary environment and gain experience in presentation and publication of research work.</p> <h3>References</h3> <p>Pflanzner T, Kuhlmann CR, Pietrzik CU.
