Co-expression of HLA DR3 and DQ8 results in the development of spontaneous insulitis and loss of tolerance to GAD65 in transgenic mice

Specific HLA DQ and DR alleles have been associated with susceptibility to
type 1 diabetes. HLA DQ8 and DQ2 have been shown to strongly predispose to
disease and to be in linkage disequilibrium with at-risk DR4 and DR3
alleles, respectively. Inheritance of a mixed DR3/DR4 haplotype confers the
greatest risk. A double transgenic mouse expressing both DR3 and DQ8 was
generated to investigate potential major histocompatibility complex class
II interactions. The DR3/DQ8 transgenic mice developed a spontaneous loss
of tolerance to GAD65, in which the T-cell response to GAD65 was restricted
by HLA DR. Although the mice also showed spontaneous insulitis, they did
not progress to overt diabetes. Mice expressing either transgene (DQ8 or
DR3) alone showed mild infiltration of their islets, which disappeared when
DQ8 or DR3 was co-expressed with a resistant DR2 allele or the neutral DQ6
allele. Therefore, in a fashion analogous to human diabetes, the murine
model demonstrated a requirement for a combination of at-risk DR and DQ
allotypes for the initiation of spontaneous autoimmunity.
