Area of Science:

  • Immunology
  • Cellular Signaling

Background:

  • T-cell receptor (TCR) stimulation initiates distinct intracellular phosphorylation patterns.
  • These patterns are crucial for understanding cellular signaling pathways and responses to perturbations.
  • Characterizing these dynamic changes over time is essential in immunology research.

Purpose of the Study:

  • To develop an efficient method for analyzing T-cell signaling.
  • To enable the simultaneous assessment of multiple sample conditions within a single experiment.
  • To optimize resource utilization in phospho-staining and flow cytometry protocols.

Main Methods:

  • A novel barcoding strategy using two fluorescent dyes was implemented.
  • This method allows for the consolidation of up to 24 distinct sample conditions.
  • The protocol integrates phospho-staining with flow cytometry analysis.

Main Results:

  • The developed method enables efficient sample barcoding and consolidation.
  • Significant savings in time and reagents were achieved compared to traditional methods.
  • The protocol facilitates detailed analysis of TCR-induced phosphorylation patterns.

Conclusions:

  • This optimized protocol streamlines the study of T-cell signaling pathways.
  • The barcoding approach enhances throughput and reduces experimental costs.
  • This method is valuable for characterizing signaling dynamics and pathway perturbations in T lymphocytes.
