Suprabasin-derived polypeptides: SBSN(50-63) induces inflammatory response via TLR4-mediated mast cell activation.
Article in Inflammopharmacology, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Psoriasis is a chronic, relapsing, immune-mediated, and papulosquamous skin disorder. Excessive mast cell activation, in psoriatic lesions, contributes to inflammation. Various endogenous peptides can participate in the pathogenesis of inflammatory diseases by activating mast cells. Suprabasin (SBSN) is expressed in multiple epithelial tissues and it regulates the normal epidermal barrier function. We have recently shown that suprabasin-derived polypeptides, SBSN(50-63), are significantly increased in psoriatic lesions, through differential peptide analysis. This study was conducted to clarify whether SBSN(50-63) plays a pivotal role in activating mast cells and mediating proinflammatory cytokines and chemokines production in psoriasis. The increased expression of SBSN in psoriatic lesions was confirmed by bioinformatics analysis, PCR and ELISA. Wild-type mice injected subcutaneously with SBSN(50-63) exhibited infiltration of inflammatory cells and the release of cytokines in vivo. SBSN(50-63) stimulated mouse primary mast cells (MPMC) and the laboratory of allergic disease 2 (LAD2) human mast cells to produce more inflammatory mediators than the control group, which were measured ex vivo and in vitro. Toll-like receptor 4 was identified as the receptor of SBSN on mast cells by molecular docking analysis, molecular dynamics simulation, and siRNA transfection. Collectively, SBSN(50-63) could activate mast cells through TLR4, which may increase the inflammatory response in psoriasis.
