| Outline of Final Research Achievements |
Calorie restriction (CR) is known to decrease the risk of disease onset resulting in lifespan elongation. Xerostomia is accompanied with aging, however, the pathogenesis is unknown yet and effective treatment has not been established. We studied the effect of CR on xerostomia accompanied with aging.Method Twelve-month-old male C57BL/6 mice were divided into ad libitum-fed (AL) group and CR group. The amount of food intake in CR group was 35% less than in AL group. The saliva secretion was measured after three and six months of CR. At the end of experiment, salivary glands were extracted following histological and gene expression analysis.Results The amount of saliva secretion decreased with aging in AL group, whereas increased saliva secretion was seen from three months after CR. Remarkable lymphocyte infiltration into salivary glands in AL group mice, however, lymphocyte infiltration was not obvious in CR group mice.
