Analysis of Vβ-Segment Diversity of T-Cell Receptor in Residents of the Techa Riverside Villages Chronically Exposed to Radiation in the Long-Term Period

The study revealed a statistically significant increase in the number of Vβ3 and Vβ5.2 T-cell receptor segments in exposed individuals relative to the comparison group (p = 0.03 and p = 0.003, respectively). It was also shown that the distribution of the Vβ-segments of the T-cell receptor is uneven in both study groups. However, there was no significant difference between the repertoires of the T-cell receptor of the studied groups in the Gini-TCR index (p = 0.14).
