Abstract: Genetically modified mice characterized by one or more symptoms or signs associated with expression of human APOE4p and mouse Trem2p and relevant to non-familial late-onset Alzheimer's disease are provided wherein the genome of the mouse includes: 1) a DNA sequence encoding a human APOE4 protein (APOE4p) operably linked to a promoter; and 2) a DNA sequence encoding a mouse Trem2 protein having a mutation p,R47H (Trem2p) operably linked to a promoter, such that the mouse expresses human APOE4p and mouse Trem2p. Methods ace provided for screening for a compound for use in the treatment of Alzheimer's disease using such genetically modified mice.

Abstract: The present disclosure provides a genetically modified mouse comprising a genomic nucleic acid encoding human APOE4, a genomic nucleic acid encoding mouse TREM2 modified to include a R47H substitution, and at least one genomic modification selected from the group consisting of: (a) a genomic nucleic acid encoding mouse ABCA7 modified to include an A 1541 G substitution; (b) a genomic nucleic acid encoding mouse APP modified to include G601R, F606Y, and R609H substitutions; (c) a genomic nucleic acid encoding mouse PLCG2 modified to include a M28L substitution; (d) a genomic nucleic acid encoding mouse MTHFR modified to include a A262V substitution; (e) an inactivated Ceacam1 allele; and (f) an inactivated Il1rap allele. Methods of producing the genetically modified mouse and methods of using the genetically modified mouse are also provided.
