Understanding parasite-brain microvascular interactions with engineered 3D blood-brain barrier models

Area of Science:

• Neuroscience
• Microbiology
• Biomedical Engineering

Background:

• Microbial interactions with the blood-brain barrier (BBB) are pathogenic and poorly understood.
• Parasite interactions with brain microvasculature are complex and difficult to study with traditional models.
• Existing animal models and 2D in vitro cultures have limitations in recapitulating BBB complexity.

Purpose of the Study:

• To review design considerations and methodologies for engineering 3D blood-brain barrier models.
• To highlight the advantages and limitations of current engineered BBB models.
• To propose applications of these models for studying parasite interactions with the BBB.

Main Methods:

• Review of engineering strategies for creating 3D microvessel models.
• Analysis of BBB properties, physiology, and function in engineered models.
• Discussion of compatibility with advanced imaging and molecular biology techniques.

Main Results:

• Engineered 3D BBB models mimic brain microvasculature architecture and BBB properties.
• These models offer enhanced control over experimental parameters.
• They provide a more accurate platform for studying complex biological interactions.

Conclusions:

• 3D engineered BBB models represent a significant advancement over traditional research methods.
• These models are suitable for investigating mechanisms of BBB disruption by parasites.
• Further development and application of these models are crucial for understanding neuro-infectious diseases.
