ANGPTL3 in Podocytes Contributes to the Pathogenesis of Lupus Nephritis by Activating MSR1 in MacrophagesKidney diseases (Basel, Switzerland) · 2026
Summary (written by the submitters)
Lupus nephritis (LN), a severe complication of systemic lupus erythematosus (SLE), is driven by immune complex deposition and inflammatory renal injury. This study uncovers a novel mechanism in which podocyte-derived angiopoietin-like protein 3 (ANGPTL3) exacerbates LN pathogenesis through macrophage scavenger receptor 1 (MSR1)-mediated activation.

Protein interaction screening revealed direct binding between ANGPTL3 and MSR1, a macrophage-enriched receptor. Clinical analyses demonstrated elevated glomerular expression of ANGPTL3 and MSR1 in LN patients, correlating with reduced renal function and histopathological damage. In vitro, ANGPTL3-overexpressing podocytes activated macrophages in an MSR1-dependent manner. RNA sequencing of ANGPTL3-stimulated bone marrow-derived macrophages (BMDMs) identified robust activation of interferon signaling pathways, with key genes (Tnip3, Isg20). Silencing Msr1 abolished these effects, suppressing interferon-related gene expression. In the pristane-induced lupus model, ANGPTL3 and MSR1 co-localized with infiltrating macrophages in injured glomeruli, mirroring human LN pathology. These findings establish the ANGPTL3-MSRI axis as a critical driver of macrophage activation and interferon signaling in LN, highlighting ANGPTL3 as a promising therapeutic target to mitigate immune-mediated renal injury in SLE.

Download · which file do I need?

Direct links to NCBI and ENA, no account and no request form. Pick by what you want to do: take the small processed table to look, the supplementary files to re-analyse, or the original raw data to start over.

1 · Just have a look

Processed table

The series matrix: one table of values per sample as the submitters processed it. The smallest download, and it opens in Excel or R. Start here to see what the data look like.

2 · Re-analyse it

Supplementary files

The count tables and other files the authors uploaded. Take only the samples you need, or the whole study as GSE302297_RAW.tar (it can run to tens of gigabytes).

3 · Start from the raw reads

Raw sequencing reads

The original FASTQ files, straight from the sequencer, held at ENA. Large, and you align them yourself, so only choose this if you need to re-process the study from scratch.

What the files usually look like: For RNA-seq the counts are usually a table among the supplementary files (look for 'counts', 'expression', 'FPKM' or 'TPM' in the file name). The series matrix of a sequencing study is sometimes nearly empty.

Also filed as BioProject PRJNA1289818 and SRA study SRP599941. Searching any of these in the dataset finder brings you back here.

Study design
3 × NC-CON vs 3 × siMSR1-CON vs 3 × NC-ANGPTL3 vs 3 × siMSR1-ANGPTL3

Supports a between-group comparison across 12 samples.

How we read this: 4 replicated groups read from 12 sample titles; they account for 12 of them. These groups are guessed from the sample names, not taken from the paper, so check them against the sample list below before relying on them.
