Synergistic effects of LCN2 and TWEAK on the progression of psoriasis.
Article in Cellular & molecular immunology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
Lipocalin 2 (LCN2) and the TWEAK/Fn14 signaling pathways are pivotal in psoriasis, influencing epidermal development, inflammatory cell chemotaxis, and inflammatory factor release. Despite their significant roles, the intricate relationship between LCN2 and TWEAK/Fn14 pathways remains unclear. Our study revealed the correlation between the expression of TWEAK, LCN2, and Fn14 in psoriatic lesions. We found that TWEAK is expressed by keratinocytes and macrophages, while LCN2 is expressed by keratinocytes and neutrophils. Surface plasmon resonance experiments demonstrated binding between LCN2 and Fn14, which was further validated by co-immunoprecipitation and cellular co-localization via immunofluorescence. In vitro, LCN2 promoted macrophage differentiation and TWEAK secretion, enhanced TWEAK and Fn14 expression in keratinocytes, and activated the MAPK signaling pathway. TWEAK upregulated LCN2 expression in neutrophils but not in keratinocytes. Bulk RNA-seq analysis revealed a synergistic effect of LCN2 and TWEAK in promoting inflammatory cytokine expression in keratinocytes, with enhanced MAPK pathway activation in the presence of M5 cytokines. Lcn2 knockout reduced Fn14 expression in skin lesions and serum TWEAK levels of imiquimod-induced murine psoriasis model, while Fn14 knockout attenuated the epidermal hyperplasia-promoting effects of TWEAK and LCN2. Overexpression of Fn14 in keratinocytes led to higher TWEAK expression upon LCN2 stimulation, suggesting a self-reinforcing loop among TWEAK, LCN2, and Fn14. We propose that LCN2 synergizes with TWEAK through Fn14 to drive psoriasis pathogenesis.
