Calpastatin prevents Angiotensin II-mediated podocyte injury through maintenance of autophagy.

Kidney Int 2021 07 3;100(1):90-106. Epub 2021 Mar 3.

Université de Paris, PARCC, Inserm, Paris, France. Electronic address:

The strong predictive value of proteinuria in chronic glomerulopathies is firmly established as well as the pathogenic role of angiotensin II promoting progression of glomerular disease with an altered glomerular filtration barrier, podocyte injury and scarring of glomeruli. Here we found that chronic angiotensin II-induced hypertension inhibited autophagy flux in mouse glomeruli. Deletion of Atg5 (a gene encoding a protein involved autophagy) specifically in the podocyte resulted in accelerated angiotensin II-induced podocytopathy, accentuated albuminuria and glomerulosclerosis.

APOL1 C-Terminal Variants May Trigger Kidney Disease through Interference with APOL3 Control of Actomyosin.

Cell Rep 2020 03;30(11):3821-3836.e13

Laboratory of Molecular Parasitology, IBMM, Université Libre de Bruxelles, 6041 Gosselies, Belgium. Electronic address:

The C-terminal variants G1 and G2 of apolipoprotein L1 (APOL1) confer human resistance to the sleeping sickness parasite Trypanosoma rhodesiense, but they also increase the risk of kidney disease. APOL1 and APOL3 are death-promoting proteins that are partially associated with the endoplasmic reticulum and Golgi membranes. We report that in podocytes, either APOL1 C-terminal helix truncation (APOL1Δ) or APOL3 deletion (APOL3KO) induces similar actomyosin reorganization linked to the inhibition of phosphatidylinositol-4-phosphate [PI(4)P] synthesis by the Golgi PI(4)-kinase IIIB (PI4KB).

Glomerular podocytes in diabetic renal disease.

Adv Clin Exp Med 2019 Dec;28(12):1711-1715

Voivodeship Specialty Hospital, Center for Research and Development, Wrocław, Poland.

Diabetic nephropathy (DN) is the most common cause of end-stage renal disease (ESRD), both in the USA and in Europe; moreover, its incidence is rising worldwide. The main laboratory markers of DN progression are albuminuria and a reduction in glomerular filtration rates, although progression of the disease has been observed even in the absence of these biomarkers. Renal impairment, associated with diabetes, results from damage to the glomerular filtration barrier, at the level of highly differentiated glomerular epithelial cells: podocytes. Read More

Focal segmental glomerulosclerosis ACTN4 mutants binding to actin: regulation by phosphomimetic mutations.

Sci Rep 2019 10 29;9(1):15517. Epub 2019 Oct 29.

Departments of Pathology, University of Pittsburgh, Pittsburgh, PA, 15213, USA.

Natural mutations such as lysine 255 to glutamic acid (K to E), threonine 259 to isoleucine (T to I) and serine 262 to proline (S to P) that occur within the actin binding domain of alpha-actinin-4 (ACTN4) cause an autosomal dominant form of focal segmental glomerulosclerosis (FSGS) in affected humans. This appears due to elevated actin binding propensity in podocytes resulting in a 'frozen' cytoskeleton. What is challenging is how this cellular behavior would be compatible with other cell functions that rely on cytoskeleton plasticity. Read More
