CTLA4-Ig Abatacept Ameliorates Proteinuria by Regulating Circulating Treg/IL-17 in Adriamycin-Induced Nephropathy Rats.

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
objectiveThis study is aimed at investigating the efficacy of CTLA4-Ig abatacept in normalizing proteinuria and its possible mechanism in adriamycin-induced nephropathy (AIN) rats.
methodsA total of 32 healthy male Sprague-Dawley rats were randomly divided into a normal group, an AIN group, an abatacept group, and a prednisone group. Adriamycin (6.5 mg/kg) was injected once via the tail vein of rats to induce nephrotic syndrome. After adriamycin treatment, the abatacept group rats were given abatacept (0.5 mg/kg) once by intraperitoneal injection on day 14. In addition, the prednisone group rats were given prednisone (12.5 mg/kg) daily consecutively by gavage from day 14 to day 21. Blood, urine, and kidney tissue specimens were collected when sacrificed on day 21. The 24-hour urinary protein, serum albumin, cholesterol, creatinine, and urea nitrogen were then detected. An enzyme-linked immunosorbent assay was used to determine the level of urine CD80 and serum IL-17. Flow cytometry was used to investigate the prevalence of circulating Treg. Hematoxylin-eosin staining and electron microscopy were used for a renal histological study. Immunofluorescence staining was performed to confirm the CD80 expression of renal tissue.
resultsThe 24-hour urinary protein of the abatacept group was significantly lower than that of the prednisone group and the AIN group. The level of urine CD80 of the abatacept group was significantly lower than that of the AIN group. Compared with the AIN group and the prednisone group, the circulating Treg prevalence of the abatacept group was significantly higher, while the level of serum IL-17 was lower. A negative kidney staining of CD80 expression was demonstrated in each group in this study. The 24-hour urinary protein had a negative correlation with the circulating Treg prevalence and Treg/IL-17 and a positive correlation with the urine CD80 and serum IL-17. Urinary CD80 had a positive correlation with serum IL-17 and no correlation with the circulating Treg prevalence.
conclusionsCTLA4-Ig abatacept can reduce proteinuria of adriamycin-induced nephropathy rats, possibly at least partially as a result of regulating circulating Treg/IL-17. CTLA4-Ig abatacept could be a promising regimen for idiopathic nephrotic syndrome.
