Although various pro- and anti-inflammatory T cell subsets have been observed in murine and human atherosclerosis, principal issues of T cell immunity remain unanswered: Is atherosclerosis progression critically affected by aberrant T cell responses? Are tolerance checkpoints compromised during atherosclerosis progression? Answers to these questions will determine if we are at the cusp of developing T cell-dependent therapeutic strategies. Rapid advances in single cell RNA sequencing (scRNA-seq) and single cell α/β T cell receptor (TCR) (scTCR) sequencing allows to address these issues in unprecedented ways. The majority of T cells recognize peptide antigen-MHC complexes presented by antigen-presenting cells which, in turn, trigger activation and proliferation (clonal expansion) of cognate TCR-carrying T cells. Thus, clonal expansion and their corresponding transcriptome are two similarly important sides of T cell immunity and both will-as hypothesized-affect the outcome of atherosclerosis. Here, we combined scRNA-seq and scTCR-seq in single cells. Moreover, we provide single T cell transcriptomes and TCR maps of three important tissues involved in atherosclerosis This approach is anticipated to address principal questions concerning atherosclerosis autoimmunity that are likely to pave the long sought way to T cell-dependent therapeutic approaches.
