WebApr 13, 2024 · The advent of immunotherapy has made an indelible mark on the field of cancer therapy, especially the application of immune checkpoint inhibitors in clinical practice. Although immunotherapy has proven its efficacy and safety in some tumors, many patients still have innate or acquired resistance to immunotherapy. The emergence of this … WebThe TCR, a defining structure of T cells, is a transmembrane heterodimer consisting of either an alpha and beta chain or delta and gamma chain linked by a disulphide bond. Within these chains are complementary determining regions (CDRs) which determine the antigen to which the TCR will bind.

WebThe B-cell receptor (BCR) complex consists of two immunoglobulin heavy chains (Igh), and two light chains (Igκ and Igγ). Heavy chains are encoded by the Igh locus; light chains are encoded by the Ig κ or Ig γ locus. In B cells, three-dimensional structural changes at the Igh locus contribute to the creation of a diverse antigen BCR repertoire.
