T-cell receptor sequences correlate with and predict gene expression levels in T cells.


ABSTRACT: T cells exhibit high heterogeneity in both their gene expression profiles and antigen specificities. We analyzed fifteen single-cell immune profiling datasets to systematically investigate the association between T-cell receptor (TCR) sequences and the gene expression profiles of T cells. Our findings reveal that T cells sharing identical or similar TCR sequences tend to have highly similar gene expression profiles. Additionally, we developed a foundational model that leverages TCR information to predict gene expression levels in T cells.

T cells exhibit high heterogeneity in both their gene expression profiles and antigen specificities, but the precise relationship between these two features remains largely unknown. Utilizing a large-scale single-cell immune-profiling dataset that includes both T cell receptor (TCR) sequences and gene expression profiles of individual cells, we systematically investigated how the transcriptional profiles of T cells are linked to their TCR sequence similarity. We observed that T cells sharing the  ...[more]
