| abstractText | Unstimulated monocytes of at-risk/type 1 diabetic humans and macrophages of the NOD mouse have markedly elevated autocrine GM-CSF production and persistent STAT5 phosphorylation. We analyzed the relationship between GM-CSF production and persistent STAT5 phosphorylation in NOD macrophages using reciprocal congenic mouse strains containing either diabetes-susceptible NOD (B6.NODC11), or diabetes-resistant C57L (NOD.LC11) loci on chromosome 11. These intervals contain the gene for GM-CSF (Csf2; 53.8 Mb) and those for STAT3, STAT5A, and STAT5B (Stat3, Stat5a, and Stat5b; 100.4-100.6 Mb). High GM-CSF production and persistent STAT5 phosphorylation in unactivated NOD macrophages can be linked to a region (44.9-55.7 Mb) containing the Csf2 gene, but not the Stat3/5a/5b genes. This locus, provisionally called Idd4.3, is upstream of the previously described Idd4.1 and Idd4.2 loci. Idd4.3 encodes an abundance of cytokine genes that use STAT5 in their macrophage activation signaling and contributes approximately 50% of the NOD.LC11 resistance to diabetes. |
