Although the maximum mutations were observed in the NS5 region that correlated with both TRDV and TRGV, one mutation, in particular T10407C, was positively and significantly correlated with both TRDV and TRGV in the severe patients only. |

Abstract
|
Despite recognizing the immune response's role in dengue progression, the intricate dynamics of T cell receptor (TCR) variations across DENV infection severities remain elusive. This study addresses this gap by analyzing in-house generated RNA-seq data from 112 dengue patients with varying disease severities. Our findings reveal that severe dengue patients exhibit pronounced clinical manifestations including leukopenia, thrombocytopenia, and elevated lymphocyte levels, Intriguingly, these patients also showed increased diversity in gamma and delta TCR chains, unique TRGV and TRBV segment usage, and extended delta-CDR3 sequences, suggesting specialized inflammatory functions. Furthermore, mutations in the NS5 and 3'UTR regions of the dengue genome correlated with increased TRDV and TRGV chains, indicating a significant role for these mutations in the prevalence of specific TCR chains during severe infections. Overall, the study highlights the complex role of TCR repertoire in dengue pathogenesis, enhancing our understanding of TCR dynamics for future infectious diseases.
