Outline of Final Research Achievements

Calcium sensing receptor localized in the basolateral membrane of type B intercalated cell (IC-B) of cortical collecting duct. We investigated the role of CaSR in IC-B by using Pendrin KO and WT mice treated for 7 days with low Pi diet (0.02% Pi). Serum [Ca] were significantly increased in Pendrin KO and WT mice with low Pi diet, compared with normal diet. Plasma pH was decreased significantly in WT mice but not changed in Pendrin KO mice. Urine pH was increased in WT mice, decreased in Pendrin KO mice. In conclusion, alkalinuria with low Pi diet was derived from luminal Pendrin in mouse kidney IC-B. Basolateral CaSR in IC-B may activate the Pendrin with hypercalcemia.

Academic Significance and Societal Importance of the Research Achievements

カルシウム感知受容体(CaSR)は、腎集合管間在細胞type-Aの管腔膜側に発現し、高Ca尿時に酸分泌を亢進させ、尿路結石の予防に関与していると考えられてきた。しかしながら、CaSRは腎集合管間在細胞type-B(IC-B)に発現し、CaSRのシグナルはPendrinに作用しアルカリ分泌を亢進させていることを明らかにした。また、低リン食負荷による高Ca血症誘導時には、IC-Bからアルカリが過剰に分泌され、血液は酸性化する。このようなメカニズムによるアシドーシスはこれまで報告がなく、新しい病態モデルに成り得る可能性がある。
