Outline of Final Research Achievements

Serum SEMA4A levels were significantly higher in patients with ECRS than in those with other diseases. Serum SEMA4A levels were not correlated with clinical disease activity of ECRS. There were no significant differences in in vivo peritoneal migration, in vitro degranulation between eosinophils derived from Wild type (WT) and SEMA4A deficient mice.
BMDEo from SEMA4A deficient mice may produce larger amount of CXCL12 than those from WT mice. Recombinant SEMA4A enhanced the production of MMP-1 from Human nasal epithelial cells (HNEpC).
