| Outline of Final Research Achievements |
The progression of chronic lesions such as interstitial fibrosis, as well as macrophage (MQ) accumulation are common futures observed in the course of progressive chronic kidney diseases. This study tried to identify a chronic kidney disease-specific MQ which are associated with chronic lesions irrespective of the nature of the underlying disease.
We found that M2-type activated MQs; MQs expressing CD163, CD204, or CD36 as M2-type MQ antigens were involved in the progression of chronic lesions. In particular, CD163+ M2-type MQ as the main MQ population associated with interstitial fibrosis across a range of progressive forms of kidney disease, suggesting a functional role for this MQ subset in renal fibrosis. Since M2-type MQ can be rather activated by glucocorticoid, another immunosuppressive drug such as purine nucleoside antimetabolite might be useful to regulate their activation.

本研究により同定された腎慢性病変の進展に関わる腎疾患特異的MQは、全ての慢性腎臓病（CKD）の治療ターゲットであり、その制御法（治療法）の開発は現在まだ進行中の研究課題であるが、現在社会問題となっているCKD患者および透析患者（末期腎不全患者）の増加に歯止めをかけるための活路を見出す課題である
