Background Psoriasis is a chronic inflammatory disease associated with abnormalities in the immune system. Microsomal prostaglandin E synthase-1 (mPGES-1), a terminal enzyme for prostaglandin (PG) E2 biosynthesis, is highly expressed in the skin of psoriasis patients. However, the detailed role of mPGES-1 in psoriasis remains unclear. In the present study, we aimed to investigate the role of mPGES-1 in psoriasis-like skin inflammation induced by imiquimod (IMQ), a well-established model of psori

Guttate psoriasis (GP) is a variant of psoriasis. Approximately 2-4% of the world population is affected by psoriasis; of this, about 30% will be diagnosed with guttate psoriasis. GP primarily affects children and young adults. Like other psoriasis, guttate psoriasis is an immune-mediated dermatological disorder. GP is distinct, given it is classically an acute rash following a streptococcal infection.Weiterlesen

Background: Psoriasis is a chronic inflammatory disease associated with high morbidity and few cases of sustained remission. Innovative immunomodulatory therapies, including fibroblast-based cell therapies, offer promising alternatives. This study investigates the therapeutic potential of human dermal fibroblasts (HDFs) organized into three-dimensional (3D) spheroids in a mouse model of imiquimod (IMQ)-induced psoriasis. Methods HDF spheroids were cultured using Elplasia microcavity plates, an

Background Psoriasis has been associated with an increased risk of various cancers, including thyroid cancer (TC), yet the molecular mechanisms linking these two diseases remain unclear.Objective This study aimed to identify and analyze the differentially expressed genes (DEGs) between TC and psoriasis using bioinformatics approaches to explore potential molecular mechanisms and shared pathways. To the best of our knowledge, this is the first bioinformatics-based study to systematically identify

Objective Psoriatic arthritis (PsA) is a chronic immune-mediated inflammatory arthritis that develops in 30% of patients with psoriasis, leading to increased morbidity and mortality and reduced quality of life. MicroRNAs (miRNAs) modulate gene expression and have been associated with the pathogenesis of immune-mediated disorders. We aimed to identify miRNAs that can be used as biomarkers for the development of PsA in patients with psoriasis.Methods miRNA expression levels were assessed in serum

Background Psoriasis is an inflammatory disorder characterized by scaly erythematous plaques and significant comorbidities. Recent studies have suggested that impaired mitophagy, the cellular mechanism for removing dysfunctional mitochondria, may contribute to the pathogenesis of psoriasis.Methods In this study, we analyzed bulk RNA sequencing data from 167 healthy individuals and 177 patients with psoriasis obtained from the Gene Expression Omnibus database (GSE30999 and GSE54456). Mitophagy-re

Psoriasis is an inflammatory skin disease, and current treatments have their own limitations, including moderate treatment effectiveness, poor compliance, and potential safety risks, etc. Therefore, the primary focus of this study is to explore novel molecular targets and improve the diagnosis and treatment of psoriasis patients. In this study, comprehensive bioinformatics analysis was performed on the expression profiles of tissue samples from patients with psoriasis in the clinical trial of TY

Background Psoriasis is an immune-mediated skin disease where Th17 cell differentiation and IL-17 secretion play critical roles. This study investigates key exosomal ncRNAs regulating the Th17/IL-17 axis in psoriasis and their mechanisms.Methods We integrated bulk RNA sequencing datasets from the GEO database to construct and evaluate exosome-related patterns. Subsequently, exosome-related ncRNAs in psoriasis lesions were identified primarily through weighted gene co-expression network analysis

Anoikis is a programmed cell death that occurs when cells detach from the extracellular matrix (ECM). Its role in psoriasis remains unclear. This study aims to explore the relationship between psoriasis and apoptosis, focusing on anoikis-related mechanisms. Differentially expressed genes (DEGs) in psoriasis were identified using the GEO database and overlapped with anoikis-related genes from GeneCards to find differentially expressed anoikis-related genes (DE-ARGs). A PPI network was constructed

Background Psoriatic arthritis (PsA) is an immune-mediated chronic inflammatory disease that causes chronic pain, psychological problems, and a significant economic burden, and therefore must be diagnosed and treated early. Existing treatments have limited efficacy and side effects.
