Conversely, we did not observe any focal (Grade II) nor diffuse (Grade III) Cav-1 immunoreactivity in several kidney conditions (e.g., arteriosclerosis-related vascular injury, interstitial fibrosis, post-transplant membranous glomerulonephritis, acute pyelonephritis, acute tubular necrosis, diabetic nephropathy plus recurrent 2,8 DHA nephropathy, TCMR). Here, CAV1 is linked to arteriosclerosis.
