| Outline of Final Research Achievements |
BPIFB1, an anti-bacterial protein, was highly expressed in the acinar cells of parotid glands of non-obese diabetic (NOD) mice, an animal model for Sjogren's syndrome, whereas, a low level of BPIFB1 expression was detected in the salivary glands of the control(C57BL/6) mice. The expression of BPIFB1 in C57BL/6 mice and ICR mice was as high as that in NOD mice at 5 weeks old, and in the control mouse embryo at the stage of 15 to 17 days.In parotid glands of NOD mice, BPIFB1 was localized in the secretory granules of the acinar cells and was secreted into saliva. BPIFB1 had N-linked glycan that reacted with Aleuria aurantia lectin. BPIFB1 was also detected in human objectives. Further studies would be required for the implication of BPIFB1 expression.
