Deciphering the Molecular Basis of Systemic Manifestations in Cutaneous Leishmaniasis Using Integrated Bioinformatics Analysis.
Article in Acta parasitologica, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
purposeCutaneous leishmaniasis is a common neglected parasitic disease in developing countries that primarily causes skin lesions but may also be associated with systemic manifestations. In this study, bioinformatics approaches were used to analyze gene expression data from blood samples of patients with cutaneous leishmaniasis in order to identify key molecular markers and mechanisms involved in the development of systemic manifestation.
methodsGene expression datasets were retrieved from GEO database and examined to determine differentially expressed genes. Protein-protein interaction (PPI) network were constructed using the STRING and HIPPIE database, Cytoscape software, and the MCODE plugin. Gene expression regulatory network (TF-miRNA-gene) were generated using the miRTarBase, TRANSFAC, and TransmiR databases. Genes with high degree and betweenness centrality in both PPI and regulatory networks were considered key genes associated with systemic manifestations. Functional enrichment and molecular pathway analyses of critical genes were performed using the DAVID database.
resultsA total of 221 genes were identified as significantly differentially expressed, including 192 up-regulated and 29 down-regulated genes. Network analyses identified critical genes, including ICAM1, CD274, BIRC3, EZH2, CTLA4, IFIH1, IER3, SAMD8, GLUL, and NAA50. These genes were mainly involved in critical functional pathways such as apoptosis, autophagy, mitophagy, TNF signaling, immune regulation, cell adhesion, natural killer (NK) cell cytotoxicity, transcription factor activation, and Signaling by NTRKs.
conclusionThis study enhances insights into the molecular mechanisms underlying the systemic effects of cutaneous leishmaniasis and highlights potential biomarkers and therapeutic targets that may aid in the development of targeted treatments.
