Conclusion

The TCR3d database has significantly expanded its content and features, enhancing its utility for immunology and structural biology research.

Supporting Evidence

  • The TCR3d database has grown by over 50% in available TCR–peptide–MHC complex structures since its original release.
  • New tools for calculating TCR engagement angles and center of mass positions have been added to the TCR3d web interface.
  • 253 affinity values for TCR–peptide–MHC complexes are now available, facilitating TCR design and affinity prediction methods.

Takeaway

TCR3d is like a big library that helps scientists understand how T cells recognize germs and can help design new medicines and vaccines.

Methodology

The database was updated with new tables for TCR mimic antibody complexes, TCR-CD3 complexes, and binding affinity data, along with tools for calculating docking geometries.
