Low T cell diversity is associated with poor outcome in bladder cancer: a comprehensive longitudinal analysis of the T cell receptor repertoire

Asbjørn Kjær, Nanna Kristjánsdóttir, Randi Istrup Juul…·Lars Dyrskjøt

This study shows that low T cell receptor diversity in bladder cancer patients is linked to poor outcomes and identifies TCR diversity as a potential biomarker for treatment.
