Outline of Research at the Start |
ペア型免疫受容体は細胞外領域に相同性の高い構造をもつが、細胞内構造の違いから細胞を活性化する受容体とそれを抑制する受容体に分けられる。最近の研究から、ある種のペア型免疫受容体は特定の生体内脂質を認識してアレルギーや炎症を促進あるいは抑制することが明らかになった。本研究では、ペア型免疫受容体が認識する生体外脂質を同定して、ペア型免疫受容体の生体外脂質認識によるアレルギー・炎症の新規制御機序を解明する。

Outline of Final Research Achievements |
We performed binding and reporter assays using an extracellular domain of leukocyte mono-immunoglobulin-like receptor (LMIR), which belongs to paired immune receptor family, to identify the LMIR ligands included in foreign bodies. We found that an activating receptor LMIR5 recognized the water-soluble molecule contained in Aspergillus, a type of fungus. In addition, intranasal administration of aqueous solution, containing this molecule, induced airway and lung inflammation by acting on LMIR5 expressed on myeloid cells. On the other hand, we identified the unknown lipid ligands for both an activating receptor LMIR5 and an inhibitory receptor LMIR3 that were included in ragweed pollen. Thus, LMIR recognized specific ligands included in the foreign bodies, thereby possibly regulating allergy and inflammation.

Academic Significance and Societal Importance of the Research Achievements |
ペア型免疫受容体は生体内外の分子を認識して免疫を制御すると想定されるが、その全貌は明らかになっていない。本研究により、ペア型免疫受容体の一つであるLMIR分子はアスペルギルス真菌やブタクサ花粉に含まれる生体外分子を認識することが判明した。これらの結果は、LMIRが生体外分子を認識してアレルギー・炎症・感染を制御する可能性を示しており、本研究成果の学術的意義は高い。さらに、本研究成果はアレルギー・炎症・感染に対する治療法開発につながる可能性を有し、社会的意義も高いと考えられる。
