PD-L1
Article in Frontiers in immunology, 2025. 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
Background: Halo nevi are clinically common and are characterized by a circle of leukoderma around the central melanocytic nevus. Studies have shown that the pathogenesis of halo nevi is similar to that of vitiligo and is associated with the role of CD8⁺ T lymphocytes in melanocyte destruction. Histopathological findings have revealed neutrophil infiltration in halo nevi; however, the specific immune mechanisms involving neutrophils have not been thoroughly investigated. In the present study, we investigated the role of neutrophils in halo nevi using histopathological and immunological analyses. Methods: To this end, we examined the infiltration patterns of immune cells in halo nevi, with a particular focus on IFN-γ-induced PD-L1 expression in neutrophils and its potential immunoregulatory effects. Results: The results demonstrated that IFN-γ expression in the lesional skin of halo nevi contributed to the induction of PD-L1 expression in neutrophils. PD-L1⁺ neutrophils promoted apoptosis and suppressed the function of CD8⁺ T lymphocytes. Notably, some halo nevi showed a tendency to spontaneous regression, but the underlying mechanisms remain unclear, and this regulatory mechanism influences the local immune response and may facilitate the repigmentation of the surrounding leukoderma in halo nevi. Conclusions: This study is the first to explore the involvement of neutrophils in halo nevi and reveal the potential immunoregulatory role of PD-L1 in this process. The elucidation of this mechanism not only provides a more comprehensive understanding of autoimmune skin diseases but may also offer new strategies for targeted therapy in other related disorders, such as vitiligo.
