AL(light chain)-amyloidogenesis by mesangial cells involves active participation of lysosomes: An ultrastructural study.

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
Amyloid formation by cells is a stepwise process that occurs in macrophages and cells capable of transforming into a macrophage phenotype. One such cell is the mesangial cell in the kidney. It has been shown that mesangial cells are engaged in AL (light chain associated)- amyloidogenesis after transforming phenotypically from a smooth muscle to a macrophage phenotype. The actual process of amyloid fibril formation has not been dissected. This ultrastructural study which includes the examination of lysosomal gradient specimens addresses this issue by analyzing the sequence of events that takes place as fibrils are formed in endosomes and lysosomes. The findings indicate that fibrillogenesis begins in endosomes but is completed and most pronounced in the lysosomal compartment. As early as 10 min after incubation of human mesangial cells with AL-LCs, amyloid fibrils are formed in endosomes but mostly occurs in the mature lysosomal compartment. This is the first time that fibril formation is demonstrated experimentally occurring inside human mesangial cells and the entire sequence of events taking place is elucidated.
