Current Research

The goal of Dr. Clare-Salzler’s laboratory is to define the immunopathogenesis of type-1 diabetes. To accomplish this goal Dr. Clare-Salzler studies immune cells from the non obese diabetic (NOD) mouse and from humans with a defined high-risk for type-1 diabetes.  His laboratory has focused many of their studies on the biology of antigen presenting cell populations, e.g. macrophages and dendritic cells and determining their role in the immunopathogenesis of this disease.  Studies to date indicate that dendritic cells presenting islet antigens impart tolerance and block the development of autoimmune disease in the NOD mouse. Other studies indicate defects in myeloid cells, including monocytes, macrophages, and myeloid dendritic cells contribute to the pathogenesis of this disease.  In addition, studies in his laboratory indicate defects in activation induced cell death, a critical mechanism of peripheral  tolerance, in both NOD mice and in humans with a risk for type-1 diabetes.

To determine the genetic contributions to the immunophenotypes described above Dr. Clare-Salzler’s laboratory is examining these in congenic mice with defined regions of NOD chromosomes on the C57BL/6 background. This analysis allows one to determination which regions NOD chromosomes controls the immunophenotype, e.g. defective deletional tolerance.

Using this approach the laboratory defined an abnormal expression of cyclooxygenase II (Cox II) in monocytes and macrophages which leads to heightened prostaglandin metabolism in the NOD mouse and also in humans who are at risk for type-1 diabetes.  Analysis of Cox II in macrophages of congenic mice indicates that this phenotype is controlled by two trans-activating genes from two separate regions of mouse chromosome 1. The generation of new congenic strains with shorter intervals will allow for eventual identification of the genes responsible for this phenotype by positional cloning.  The same approach has also defined two regions of the NOD genome that contribute to the defects in deletional tolerance, one in a region on mouse chromosome 17, perhaps the MHC or a gene(s) within this region, and another contained on chromosome 1.
