Abstract

Apolipoprotein L1 (APOL1) risk variants greatly elevate the risk of kidney disease in African Americans. Here we report a cohort of patients who developed collapsing focal segmental glomerulosclerosis while receiving therapeutic interferon, all of whom carried the APOL1 high-risk genotype. This finding raised the possibility that interferons and the molecular pattern recognition receptors that stimulate interferon production may contribute to APOL1-associated kidney disease. In cell culture, interferons and toll-like receptor agonists increased APOL1 expression by up to 200-fold, in some cases with the appearance of transcripts not detected under basal conditions. PolyI:C, a double-stranded RNA TLR3 agonist, increased APOL1 expression by upregulating interferons directly or through an interferon-independent, IRF-3 dependent pathway. Using pharmacological inhibitors, shRNA knockdown, and chromatin immunoprecipitation, we found that the interferon-independent TLR3 pathway relied on signaling through TBK1, NF-kB, and Jak kinases, and on binding of IRF1, IRF2, and STAT2 at the APOL1 transcription start site. We also demonstrate that overexpression of the APOL1 risk variants is more injurious to cells than overexpression of the wild-type APOL1 protein. Our study illustrates that anti-viral pathways may be an important inducer of kidney disease in individuals with the APOL1 high-risk genotype and identifies potential targets for prevention or treatment.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
