OMIP-087: Thirty-two parameter mass cytometry panel to assess human CD4 and CD8 T cell activation, memory subsets,...

Area of Science:

• Immunology
• Cell Biology
• Biotechnology

Background:

• Accurate characterization of immune cells, particularly T cells, is crucial for understanding and managing diseases like infections, cancer, and autoimmunity.
• Existing methods may require significant sample volumes or lack the multiplexing capability to comprehensively analyze diverse immune subsets.
• There is a need for standardized, high-resolution panels for immune cell profiling in peripheral blood mononuclear cells (PBMCs).

Purpose of the Study:

• To develop and validate a highly reproducible 32-marker mass cytometry panel for comprehensive immune cell analysis.
• To enable detailed characterization of CD4 and CD8 T cell subsets, including memory, activation, cell cycling, and survival markers.
• To facilitate the classification of major CD4 T helper subsets within human PBMCs.

Main Methods:

• Development of a 32-color mass cytometry panel optimized for human PBMCs.
• Standardization and optimization protocols for high-throughput, reproducible immune profiling.
• Identification and gating strategies for canonical immune lineages, CD4 T cell subsets, and CD8 T cell memory populations.

Main Results:

• A highly reproducible 32-marker mass cytometry panel was successfully established.
• The panel allows for the measurement of all canonical immune lineages.
• Six distinct T cell memory subsets, activation, cell cycling, and survival markers were identified, alongside major CD4 T helper subsets.

Conclusions:

• This mass cytometry panel provides a robust and reproducible method for detailed immune cell analysis, particularly for CD4 and CD8 T cells.
• The panel's ability to characterize multiple immune parameters with limited sample input is valuable for clinical research.
• It enables comprehensive monitoring of immune responses in infectious diseases, cancer, and autoimmune conditions.
