Engineering the blood-brain-barrier

Lead Research Organisation: University of Glasgow
Department Name: School of Engineering

Abstract

Blood-brain-barrier (BBB) dysfunction is associated with key neurodegenerative diseases affecting our aging population, including Alzheimer's and Parkinson's disease. The BBB consists of specialised endothelial cells (ECs) that are separated by a thin basal lamina from a layer of associated pericytes and astrocytes. Astrocyte secrete cytokines and growth factors that increase the tightness of the endothelial layer.
This project will engineer a novel, simple yet robust in vitro model of the BBB that reproduces the main features of the physiological unit by substituting astrocytes/pericytes by a bioengineered membrane that presents growth factors very efficiently. This would facilitate screening for novel BBB treatments by pharma as well as the investigation of disease mechanisms.
The project is highly multidisciplinary and involves 3D printing, surface functionalisation with proteins and cell biology at the interface with materials.

Description We have shown that endothelial cells grown on our labs coated membranes generate the proteins we would associate with endothelial cells found in the blood brain barrier. We can quantify that this is achieved better using the coatings, and then do some further experiments to see what growth factors might make even better barriers. This can hopefully eventually be used to model diseases or disruption of the blood brain barrier, and as an initial test of whether drugs targeting the brain may be able to pass through the blood brain barrier.
Exploitation Route Our model has already been sent to two collaborators, one which works on the devastating brain cancer glioblastoma, whose treatment is vastly hindered by the blood brain barrier, as well as a group workingnn on the epithelial barrier in the lungs, which we think our base model of the insert + membrane + coatings should help improve. We are also always looking for further collaborators.

The findings from the project have also aided similar vascular-related projects within the lab.
It is the hope that the outcome of this lab will be a functional, simple and easy to use model of the blood brin barrier which others can use to test the potential of new drugs to enter the brain in the early stages of drug development, to model disease (as well as using patient-specific cells to more accurately capture what might be occuring within their anatomy) and generally be used to understand the molecular complexity within the blood brain barrier.

The hope that this project will lead to a useful paper which in turn can better help the blood brain barrier community as whole, as this simple model may make entry-level blood brain barrier research more achielable

Description Podcast: CeMi Serious Sciene 
Form Of Engagement Activity A broadcast e.g. TV/radio/film/podcast (other than news/press)
Part Of Official Scheme? No
Geographic Reach International
Primary Audience Public/other audiences
Results and Impact Formed a lab podcast named CeMi Serious Science with colleague and fellow PhD student Stylianos Orestis Sarrigiannidis, in which we interview people in STEM about their work and life in a way that should be engaging for someone without a background in scicence.

For this activity, Styli and I's role is asfollows: reaching out to poential guests for the podcast, researching guests and writing questions, performing and recording the interview, and editing the podcast episode for release.

CeMi Serious Science is released on PodBean, Stitcher, Apple Podcasts and Spotify, where on average each episode gets 200-300 listens (although listenership is increasing).

We also engage with the public through the podcast Instagram, Twitter and Reddit account, answering questions and asking if the public havbe any questions for our up and coming guests.
