- Abstract
- BB rats develop various organ-specific autoimmune diseases, e.g. autoimmune diabetes and thyroiditis and have proven important to dissect genetic factors that govern autoimmune disease development. The lymphopenia (lyp) gene (iddm2) is linked to autoimmune disease development and is a major genetic difference between diabetes-resistant (DR) and diabetes-prone (DP) BB rats. To study the effects of the lyp gene and other genes on dendritic cell (DC) differentiation from bone-marrow precursors, such differentiation was studied in BB-DP, BB-DR, Wistar and F344 control rats.
DC of BB-DP rats showed a lower MHC class II expression as compared to BB-DR, Wistar and F344 rats. LPS-maturation did not restore this low MHC class II...

To study the effects of the lyp gene and other genes on dendritic cell (DC) differentiation from bone-marrow precursors, such differentiation was studied in BB-DP, BB-DR, Wistar and F344 control rats.
DC of BB-DP rats showed a lower MHC class II expression as compared to BB-DR, Wistar and F344 rats. LPS-maturation did not restore this low MHC class II expression. DC of BB-DP rats also showed a poor capability to terminally differentiate into mature T cell stimulatory DC under the influence of LPS and produced significantly lower quantities of IL-10, yet these aberrancies were also found in BB-DR rats but did not occur in control rats.
This study thus shows that various aberrancies exist in the differentiation of myeloid DC from bone-marrow precursors in the BB rat model of organ-specific autoimmunity. These aberrancies are multigenically determined and partly associated with iddm2 (lyp gene) and partly associated with other genes in the BB rat. (Less)
