We have previously proposed that sequence variation of the CD101 gene between NOD and C57BL/6 (B6) mice accounts for the protection from type 1 diabetes (T1D) provided by the
Idd10
region, a <1 Mb region on mouse chromosome 3. Here, we provide further support for the hypothesis that
Cd101
is
Idd10
using haplotype and expression analyses of novel
Idd10
congenic strains coupled to the development of a CD101 knockout mouse. Susceptibility to T1D was correlated with genotype-dependent CD101 expression on multiple cell subsets, including FoxP3
+
regulatory CD4
+
T cells, CD11c
+
dendritic cells and Gr1
+
myeloid cells. The correlation of CD101 expression on immune cells from four independent
Idd10
haplotypes with the development of T1D supports the identity of
Cd101
as
Idd10
. Since CD101 has been associated with T regulatory and antigen presentation cell functions, our results provide a further link between immune regulation and susceptibility to T1D.
