Sugi, or Japanese cedar, is native to Japan and is considered the nation’s national tree. After World War II, the Japanese government encouraged the planting of Japanese cedar trees, which were an important resource. However, as the trees matured, large amounts of pollen were produced. Seasonal allergic rhinitis caused by these pollens has become the most common illness in Japan and is considered a national affliction. More than one-third of all Japanese persons are afflicted, and these numbers have increased in the last decade along with pollen counts.1 The information learned from this study may provide valuable insight for future allergy therapeutic design and/or diagnostic reagents.
The purpose of this study is to find out more about how allergy cells that circulate in the blood react with allergens from Japanese cedar, or Sugi, trees. Understanding these basic mechanisms of interaction may help lead to better therapies for allergy sufferers. It is important to find donors who have lived in Japan and therefore have been exposed to the cedar trees. Scientists are then able to analyze not only how individuals with cedar tree allergies react to the cedar pollen, but also how and why other individuals do not have any reaction or display symptoms when being exposed to the same cedar pollen. The goal is to ultimately improve specific immunotherapy treatments.
