CD103+/+, CD103+/−, or CD103−/− x RIP-GP or x RIP-NP mice were infected i.p. with 104 PFU LCMV Armstrong. Incidence of diabetes in males (A) or females RIP-GP (B) or males RIP-NP (C) is shown. (RIP-GP males, n: +/+=10, +/−=14, −/−=4, females, n: +/+=5, +/−=15, −/−=10, RIP-NP males, n: +/−=10, −/−=12). Mice were considered diabetic when BGVs were >300 mg/dl. Degree of insulitis was determined after staining pancreatic sections 10 wks p.i. with insulin-CD8 or insulin-CD4 (D). One representative section of islets from each group of mice (3-4 mice per group) is shown. Histological analysis was performed in tissues from the diabetic mice.
