Abstract:
This chapter describes the preparation of respiratory tract tissue from both mice and rats for the isolation of respiratory tract dendritic cells (RTDC). The methods describe in detail the preparation of cells from the respiratory tract tissue of the main conducting airways (representing mucosal populations) and peripheral lung (representing predominantly interstitial populations) in both rodent species. Our research in this area has found that these anatomical sites differ in their composition of antigen-presenting cell (APC) types including RTDC, and that phenotypic and functional differences exist in RTDC isolated from these sites. We predominantly use a flow cytometry-based approach to identify and sort RTDC as this is the most accurate way of isolating RTDC subsets in an environment where many typical dendritic cell surface markers are shared by other APC populations.
Insights
This study details methods for isolating respiratory tract dendritic cells (RTDC) from mice and rats. Different lung regions yield distinct RTDC populations, requiring precise isolation techniques for accurate analysis.
Area of Science:
- Immunology
- Cell Biology
- Respiratory Medicine
Background:
- Respiratory tract dendritic cells (RTDC) are crucial immune sentinels.
- Distinct anatomical locations within the respiratory tract harbor unique immune cell compositions.
- Understanding RTDC heterogeneity is vital for respiratory health research.
Purpose of the Study:
- To describe detailed methods for isolating RTDC from specific respiratory tract regions in rodents.
- To highlight anatomical and functional differences in RTDC from conducting airways versus peripheral lung.
- To establish a reliable method for studying RTDC subsets.
Main Methods:
- Tissue preparation from rodent respiratory tracts (conducting airways and peripheral lung).
- Cell isolation techniques optimized for mucosal and interstitial populations.
- Flow cytometry for accurate identification and sorting of RTDC subsets, overcoming shared marker issues with other antigen-presenting cells (APC).
Main Results:
- Established protocols for isolating RTDC from distinct anatomical sites in mice and rats.
- Demonstrated that conducting airways and peripheral lung harbor different types and subsets of RTDC.
- Confirmed phenotypic and functional variations in RTDC based on their anatomical origin.
Conclusions:
- Specific protocols are necessary for isolating RTDC from different respiratory tract compartments.
- Anatomical location significantly influences RTDC phenotype and function.
- Flow cytometry is essential for precise RTDC subset identification in complex respiratory tissues.
