CD36 and acute kidney injury: Next, to explore the expression of CD36 in pericytes during AKI-CKD progression, we simultaneously detected the expression of CD36 and found that its level was consistent with the progression of AKI-CKD, showing a sharp increase at IRI day 2 (2D), a slight decrease at 7D, and a subsequent increase at 30D, following the development of AKI–CKD (Fig. 2C; Supplemental Fig. B).
