简介:
Overview
This protocol provides a fast and reliable method to quantitatively measure phagocytosis of Aspergillus fumigatus conidia by human primary phagocytes using flow cytometry. It allows for the discrimination of phagocytosis from mere adhesion to leukocytes.
Key Study Components
Area of Science
- Microbiology
- Immunology
- Flow Cytometry
Background
- Phagocytosis is a critical immune response mechanism.
- Aspergillus fumigatus is a significant pathogen in immunocompromised individuals.
- Traditional methods may not effectively distinguish between phagocytosis and adhesion.
