Carries a transgene consisting of fragments of the human HLA-B*4002 gene and mouse H2-Kb gene which encodes a chimeric class I molecule consisting of the human HLA-B44 leader, α1 and α2 domains ligated to the murine α3, transmembrane and cytoplasmic H2-Kb domains
Expresses the chimeric HLA-B44 class I molecule on the surface of T and B cells. The B*40:02 allele is a member of the B44-binding supertype, which encompasses a group of HLA B alleles sharing a binding specificity for peptides with E in position 2 and aliphatic/hydrophobic residues at the C-terminus.

Useful for infectious disease research, vaccine development and testing, safety and immunogenicity testing as well as research directed towards oncology and autoimmune disorders
Permits identification of epitopes restricted to the HLA-B44 supertype

Genetic Background: CB6F1 Background
Origin: The HLA-B44 model was generated by Pharmexa-Epimmune. The model was created by microinjecting a chimeric transgene combining a fragment of the genomic clone of the human HLA-B*4002 gene that included leader sequence, α1 and α2 domains ligated to a fragment of the murine H2-Kb gene containing the α3, transmembrane and cytoplasmic domains, all under the control of the murine H2-Kb promoter. This transgene was microinjected into C57BL/6 zygotes. The resultant mice from Founder Line B44.01 were on an inbred C57BL/6 background. The line was maintained by breeding hemizygotes to wild type C57BL/6NTac mice for 4 generations. Taconic received stock from Pharmexa-Epimmune in 2008. The line was embryo transfer derived by breeding C57BL/6NTac wild type females to hemizygous males and then was intracrossed to homozygosity. The colony is maintained through breeding of homozygous males to homozygous females. In the production colony, wild type BALB/cAnNTac females are bred to homozygous males on the C57BL/6NTac background to produce CB6F1 pups.

This publication does not describe the HLA-B44 strain, but the HLA-B44 strain was generated in a similar manner to that of the other transgenic HLA mouse strains described in the publication and may be used for similar types of experiments.
