1 · What the graph read from it

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.

2 · The registry

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

Interleukin (IL)-1β is now emerging as a critical cytokine in the pathogenesis of T helper type 17 (Th17)-mediated skin diseases, including psoriasis. Psoriatic keratinocytes are a major source of IL-1β; however, the mechanisms triggering IL-1β processing remain unknown. Recently, an acute-phase protein serum amyloid A (SAA) has been identified as a danger signal that triggers inflammasome activation and IL-1β secretion. In this study, we detected increased SAA mRNA and protein expression in psoriatic epidermis. In cultured keratinocytes, SAA up-regulated the expression of pro-IL-1β and secretion of mature IL-1β. On the transcriptional level, blocking Toll-like receptor-2 (TLR-2), TLR-4 or nuclear factor kappa B (NF-κB) attenuated SAA-induced expression of IL-1β mRNA. SAA up-regulated caspase-1 and NACHT, LRR and PYD domains-containing protein 3 (NLRP3) expression in keratinocytes. Inhibiting caspase-1 activity and silencing NLRP3 decreased IL-1β secretion, confirming NLRP3 as the SAA-responsive inflammasome on the post-transcriptional level. The mechanism of SAA-triggered NLRP3 activation and subsequent IL-1β secretion was found to involve the generation of reactive oxygen species. Finally, the expression of SAA by keratinocytes was up-regulated by IL-17A. Taken together, our results indicate that keratinocyte-derived SAA triggers a key inflammatory mediator, IL-1β, via NLRP3 inflammasome activation, providing new potential targets for the treatment of this chronic skin disease.
