Aislamiento de los capilares cerebrales del cerebro humano fresco tejido

Overview

This study introduces a preclinical model using isolated brain capillaries from human brain tissue to investigate blood-brain barrier (BBB) function under both normal and pathological conditions. An optimized protocol for isolating these capillaries is detailed, enabling insights into BBB dysfunction and related signaling pathways.

Key Study Components

Area of Science

• Neuroscience
• Blood-Brain Barrier Research
• Cellular Biology

Background

• Blood-brain barrier integrity is critical for central nervous system function.
