In this work, chicken HPAIV H5N1 epitope-specific TCRalphabeta (ch-TCRalphabeta) was isolated and its structure was determined. The Calpha domain of ch-TCRalphabeta does not exhibit the typical structure of human TCRalphabeta, and the DE loop extends outward, resulting in close proximity between the Calpha domain of ch-TCRalphabeta and CD3epsilondelta/gamma. The FG loop of the Cbeta domain of ch-TCRalphabeta is shorter. The changes in the C domains of ch-TCRalphabeta and the difference in chicken CD3epsilondelta/gamma confirm that the complexes formed by TCRalphabeta and CD3epsilondelta/gamma differ from those in humans. In the chicken complex, a positively charged cleft is formed between the two CDR3 loops that might accommodate the acidic side chains of the chicken pMHC-I-bound HPAIV epitope intermediate portion oriented toward ch-TCRalphabeta. This is the first reported structure of chicken TCRalphabeta, and it provides a structural model of the ancestral TCR system in the immune synapses between T cells and antigen-presenting cells in lower vertebrates.
