Abstract
Disclosed herein are non-human animals (e.g., rodents, e.g., mice or rats) genetically engineered to express a human or humanized T cell receptor (TCR) from a human or humanized TCR locus comprising a non-human TCR non-coding sequence, and optionally a humanized T cell co-receptor (e.g., humanized CD4 and/or CD8 (e.g., CD8α and/or CD8β)), and/or a human or humanized major histocompatibility complex that binds the humanized T cell co-receptor (e.g., human or humanized MHC II (e.g., MHC II α and/or MHC II β chains) and/or MHC I (e.g., MHC Iα) respectively, and optionally human or humanized β2 microglobulin). Also provided are embryos, tissues, and cells expressing the same. Methods for making the genetically engineered animals are also provided. Methods for using the genetically engineered animals for developing human therapeutics are also provided.
