TCRdb(2.0): A comprehensive T-cell receptor sequences database

The unique features of TCRdb include:

  • Comprehensive and reliable sequences for TCR repertoire in different samples generated by a strict and uniform pipeline of TCRdb;
  • Powerful search function, allowing users to identify their interested TCR sequences in different conditions;
  • Categorized sample metadata, enabling comparison of TCRs in different sample types;
  • Interactive data visualization charts, describing the TCR repertoire in TCR diversity, length distribution and V-J gene utilization.

Newly Update

  • A substantial increase in data volume, with the number of TCR samples growing from 8,265 to 19,701 and the number of TCR sequences expanding from 277 million to about 700 million
  • Construction of the largest TCR reference in healthy samples, which contains 1,888 samples labeled as healthy controls from 40 published studies.
  • New search function, supporting batch search.
  • Redesigned download function
