ImmuneWatch DETECT finds the specificity of T cell receptor clusters in a new Science Advances paper

In less than one year since its release, ImmuneWatch DETECT has reached a significant milestone by being featured in a new research paper: T cell receptor–centric perspective to multimodal single-cell data analysis published in Science Advances earning its first official citation.

In this study, researchers used ImmuneWatch DETECT to explore the antigen-specificity of a prevalent TCR cluster across 99 of 149 samples. These clones, identified across diverse HLA types, were a mystery until ImmuneWatch DETECT predicted their specificity for riboflavin antigens presented on MR1. This insight revealed the cluster as MAIT cells, a finding later confirmed by exploring MAIT-specific markers in the gene expression data.

Why This Matters

The study highlights a shift toward a “TCR-first” approach for analysing single-cell sequencing data, which has traditionally underutilised TCR insights. By curating an atlas of 500,000 T cells spanning diseases such as melanoma, head and neck cancer, and blood cancer, the researchers addressed challenges in cell annotation, treatment-related dynamics, and public TCR clusters.

ImmuneWatch DETECT was instrumental for some of these findings, demonstrating its value as a tool for decoding TCR specificity and enabling actionable discoveries in immune research.
