• Isolation and Preparation of Cells
  
  • Treg and T Cell Isolation: Using cutting-edge techniques like cell sorting and fluorescence-activated cell sorting (FACS), we isolate highly pure populations of Tregs and T cells from peripheral blood or tissue samples.
  • Cell Viability Assessment: Cell viability is assessed using trypan blue exclusion or flow cytometry with viability dyes to ensure the integrity and functionality of the isolated cells.
  • Endothelial Cell Culture: We culture primary endothelial cells or cell lines under optimal conditions to form a confluent monolayer, closely mimicking the in vivo endothelial barrier.
• Transendothelial Migration Assay Design
  
  • Labeling and Tracking: Tregs and T cells are labeled with distinct fluorescent dyes to facilitate precise tracking during migration assays.
  • Coculture System: We set up a transwell system where T cells are placed in the upper chamber and allowed to migrate through the endothelial layer to the lower chamber, with or without Tregs.
  • Chemotactic Gradient: A chemokine gradient is established to drive T cell migration, providing a physiologically relevant stimulus.
  • Addition of Tregs: To study the effect of Tregs, they are added to the coculture system in varying ratios. This setup allows us to observe and quantify the influence of Tregs on the migration of effector T cells across the endothelial barrier.
• Assessment of Migration
  
  • Live-Cell Imaging: Utilizing real-time imaging technologies, we monitor the migration process, capturing detailed data on T cell movement across the endothelial barrier.
  • Quantification of Migrated Cells: After migration, we quantify the number of T cells that have successfully transmigrated to the lower chamber using flow cytometry or fluorescence microscopy.
  • Functional Analysis: We assess the impact of Tregs on T cell migration by comparing migration rates and patterns in the presence and absence of Tregs.
• Data Analysis and Reporting
  
  • Advanced Data Analysis: Employing sophisticated software, we analyze migration dynamics, including speed, directionality, and transmigration efficiency.
  • Comprehensive Reporting: Our detailed reports include high-resolution images, graphical representations of migration data, and thorough statistical analysis, providing clear and actionable insights.

Applications

• Investigate how Tregs influence T cell infiltration into tumors, aiding the development of immunotherapies that modulate Treg activity to enhance anti-tumor responses.
• Understand the mechanisms by which Tregs control T cell migration in autoimmune conditions, providing insights for developing treatments that restore immune balance.
