- 요약This thesis focuses on the development of novel, high-specificity platforms for targeting peptide-MHC complexes, which are critical for advancing therapeutic strategies against cancer, infections, and autoimmune diseases. I will present the TRACeRplatform (Targeted Recognition of Antigen-MHC Complex Reporter), consisting of TRACeR-IIand TRACeR-I,which enable rapid binder development and specific targeting of peptides presented by MHC-II and MHC-I molecules, respectively. The TRACeRplatform draws inspiration from the structure of the bacteria superantigen MAM and has been extensively engineered through a combined computational and experimental approach.The TRACeR-IIplatform leverages the small helical bundle scaffold from MAM with a single recognition loop for versatile binding to peptide--MHC-II complexes. This approach allows for rapid screening and in silico design of binders, as demonstrated by our success in generating binders for multiple alleles with affinities and specificity comparable to best-in-class TCRs and antibodies. TRACeR-IIeliminates the need for traditional combinatorial selection on CDR loops, facilitating streamlined development of peptide-specific binders for class-II MHCs.In parallel, TRACeR-Iis developed by repurposing the TRACeR-IIscaffold for binding MHC-I targets, aiming to address challenges in targeting peptide--MHC-I complexes. TRACeR-Iis able to target peptides on polymorphic HLA-A*, -B*, and -C* allotypes while overcoming the long-standing issue of cross-reactivity in TCRs or antibody-based platforms. TRACeR-Iemploys a unique recognition mechanism through an extended network of contacts across the peptide, achieving single-residue specificity. This platform enables the rapid identification of binders for viral and cancer-related peptides and has demonstrated efficacy in BiTEs and CAR-T cell applications.
