Targeting fibroblast activation protein-α to treat renal fibrosis.
Article in Cellular & molecular biology letters, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundRenal fibrosis is the common outcome of chronic renal disease. Currently, there are no effective therapies. Fibroblast activation and extracellular matrix accumulation are key processes driving renal fibrosis. METHODS AND
resultsFibroblast activation protein (FAP) is highly induced in injured kidneys, and immunofluorescence staining revealed that FAP is mainly expressed in Platelet-derived growth factor receptor-beta (PDGFRβ)+ and alpha-smooth muscle actin (α-SMA)+ myofibroblasts in kidney samples from mice with renal fibrosis and patients with chronic kidney diseases or post-acute kidney injury. In this study, targeting FAP as a strategy for treating renal fibrosis is tested using two preclinical animal models: the mouse models of unilateral ureteral obstruction and unilateral renal ischemia–reperfusion. Adoptive transfer of T cells expressing chimeric antigen receptor specific to FAP or administration of an FAP inhibitor (SP-13786) significantly alleviated kidney fibrosis in both mouse models. Eliminating FAP+ fibroblasts using chimeric antigen receptor T-cell (CAR-T) therapy or inhibiting the FAP prevented fibroblast overactivation, proliferation, and migration, promoted apoptosis, and effectively suppressed other myofibroblast populations.
conclusionsOverall, we report herein that targeting FAP offers a novel promising treatment approach for renal fibrosis.
