Immune Monitoring by Flow Cytometry

With the ability to detect and quantify multiple markers, flow cytometry is a powerful and widely used method for analyzing immune cells.From classifying and counting different cell types to more technically-challenging approaches like receptor occupancy and phospho-flow, Precision’s immune monitoring-specific flow cytometry services are performed on either research-grade 18 color instruments or on CLIA-certified flow cytometers. We couple these capabilities with an extensive global sample processing and logistics network, and specialty labs sites on multiple continents to support immune monitoring needs of studies anywhere in the world.

Scientific poster: Development and technical validation of tetramer staining for use as a biomarker for assessing gluten-specific T cells in clinical studies

Presented at the 18th International Celiac Disease Symposium • 4–7 September 2019 • Paris, France

Gluten-challenge in subjects with celiac disease results in a transient upregulation of gliadin-specific CD4+ T cells in the blood. Despite the increase, these cells are quite rare requiring a selective and sensitive assay for detection.

We have developed a 12-colour tetramer flow assay to enable detection and immunophenotyping of the gliadin α-I/α-II CD4+ T cells in the blood.

Conclusions

This gliadin α-I/α-II DQ2 tetramer flow cytometric assay was developed and validated to be sensitive and selective. Technical validation of the assay was successfully met and the assay performs within the precision parameters.

This assay will enable characterization of the gliadin α-I/α-II CD4+ T cells in the blood for celiac patients, providing a more comprehensive evaluation of response to new therapies and may reduce invasive biopsy-based measurements.
