Humanized dipeptidyl peptidase IV (DPP4) animals |
摘要 |
Non-human animals comprising a human or humanized DPP4 nucleic acid sequence are provided. Non-human animals that comprise a replacement of the endogenous Dpp4 gene with a human or humanized DPP4 gene, or non-human animals comprising a human or humanized DPP4 gene in addition to the endogenous Dpp4 gene are described. Non-human animals comprising a human or humanized DPP4 gene under control of human or non-human DPP4 regulatory elements is also provided, including non-human animals that have a replacement of non-human Dpp4-encoding sequence with human DPP4-encoding sequence at an endogenous non-human Dpp4 locus. Non-human animals comprising human or humanized DPP4 gene sequences, wherein the non-human animals are rodents, e.g., mice or rats, are provided. Methods for making and using the non-human animals are described. |

1. A rodent, comprising a humanization of an endogenous rodent Dpp4 gene, wherein the humanization comprises a replacement at the endogenous rodent Dpp4 locus of a rodent gene encoding an exon of an Dpp4 gene with a nucleic acid sequence encoding at least one exon of a human DPP4 gene to form a modified DPP4 gene, wherein expression of the modified DPP4 gene is under control of rodent regulatory elements at the endogenous rodent Dpp4 locus, wherein the rodent is a mouse or a rat, and wherein the rodent exhibits one or more symptoms when infected with Middle East respiratory syndrome coronavirus (MERS-CoV). |
