| Research Abstract |
We sought to determine the molecules associated with the pathogenesis of Japanese cedar pollinoisis in mouse. Experiment using KO mice showed that BLTA selectively suppressed Cry j 1-specific Th1 response in this model. Microarray analysis revealed that amounts of mRNAs for Th2 cytokines including IL-5 and IL-13 were significantly higher in submandibular lymph node from responder BALB/c mice as compared with non-responder C57BL/6 mice. On the other hand, removal of submandibular lymph node had little effect on sensitization and onset of Japanese cedar pollinosis in this model.
