Psoriasis is one of the most common chronic inflammatory skin diseases and is characterised by the uncontrolled proliferation of keratinocytes and their abnormal differentiation. Sirtuins are a group of enzymes that play an important role in post-translational modifications of proteins, such as deacetylation, poly-ADP-ribosylation, demalonylation and lipoamidation. They are found in various cell types and are involved in ribosomal DNA recombination, gene silencing and DNA repair. This study aime

Psoriatic disease encompasses psoriasis and psoriatic arthritis. It is a chronic, progressive condition and leads to irreversible joint destruction. Conventional treatments used are disease-modifying antirheumatic drugs and biologics. Janus kinase (JAK) signal transducers and activators of transcription (STAT) cell signaling protein inhibitors have shown promising results in psoriatic disease. However, JAK inhibitors have been associated with some concerning safety issues, such as cardiac risks,

Despite its efficacy, the molecular mechanisms underpinning its therapeutic action remain unclear.Purpose This study aimed to unravel the molecular mechanism of Compound Qingdai Capsule for psoriasis based on the psoriasis pathogenic pathway network, integrating multi-omics a

Psoriasis is a chronic, immune‑mediated skin disorder characterized by keratinocyte hyperproliferation, inflammatory infiltrates and systemic comorbidities. While genetic predisposition and immune dysregulation are established contributors, recent advancements in high‑throughput omics technologies have provided deeper insights into the molecular complexity of psoriasis. The present review synthesized findings from various omics layers, genomics, epigenomics, transcriptomics, proteomics, metabolo

Psoriasis is a chronic inflammatory disease mediated by the innate and adaptive immune systems, and its pathogenesis involves multiple aspects, including abnormal interleukin (IL)-23-Th17 axis, dysfunction of Tregs and other immune cells, and a complex relationship between keratinocytes and the vascular endothelium. Dysfunction of mesenchymal stem cells in psoriatic skin may also be the main reason for the dysregulated inflammatory response. Mesenchymal stem cells, a type of adult stem cells wit

Psoriasis pathogenesis involves dysregulated immune responses, yet the role of protein prenylation (particularly PGGT1B-mediated geranylgeranylation) in macrophage-driven inflammation remains poorly understood. This study aims to explore the role and molecular mechanism of protein geranylgeranyltransferase type I subunit beta (PGGT1B) in the development of psoriasis. Myeloid cell-specific PGGT1B gene knockout mice were generated, and a mouse psoriasis model was established with imiquimod to stud

Background Nail involvement is common in psoriasis, yet objective and non-invasive biomarkers of nail disease activity are limited. The biochemical composition of the nail plate may reflect local pathophysiological changes and could provide measurable indicators of disease severity.Objective To compare the nail biochemical composition between psoriatic patients with and without nail involvement, and to examine its associations with nail severity.Methods In this case-control study, nail clippings

Introduction Psoriatic arthritis (PsA) presents various imaging abnormalities in joints and diverse nail changes, but the link between nail and joint findings remains unclear. This study aimed to gain a better understanding of the relationships between nail manifestations and abnormal articular architectures by investigating the associations between nail abnormalities and articular findings in PsA-affected interphalangeal joints.Methods A total of 106 nails adjacent to PsA-affected distal interp

Psoriasis is a chronic, relapsing inflammatory skin disease. Topical treatments are the primary choice for up to 80% of psoriasis patients; however, their effectiveness is often limited by poor penetration into the skin. Nanocarriers represent a promising advancement in drug delivery systems by enhancing bioavailability and tissue penetration and reducing the frequency of dosing. This study conducted a narrative review and analyzed the characteristics of clinical trials registered on ClinicalTri

Psoriasis is a chronic, immune-mediated inflammatory skin disorder characterized by keratinocyte hyperproliferation, dysregulated immune signaling and systemic comorbidities, affecting nearly 2-3% of the global population. Although conventional therapies have improved disease management, they remain limited by poor drug penetration, systemic toxicity, adverse effects, high costs and relapse after discontinuation. The distinctive pathophysiology of psoriatic skin, with its thickened stratum corne

Psoriasis is a persistent immune-mediated inflammatory dermatosis. The treatment of psoriasis now features natural medicine as an effective new alternative because of its notable effectiveness and few side effects. Nervonic acid (NA), a long-chain fatty acid mostly sourced from the seed oils of some wild plants, exhibits significant antidepressant and anti-inflammatory properties. Nonetheless, the pathogenic effects and mechanism of NA in the pathogenesis of psoriasis are unreported. This work d

Psoriatic patients have shown higher levels of neutrophil extracellular traps (NETs) vs healthy controls. Psoriasis is often associated with other comorbidities such as cardiovascular disease. An increase in indirect markers of NETs has been found in patients with increased cardiovascular events in patients without psoriasis.We conducted a prospective observational study with psoriatic patients. A total of 39 of patients were included. Myeloperoxidase, neutrophil elastase and double-stranded DNA

Background Psoriasis is frequently associated with non-communicable disease (NCD) comorbidities, prompting interest in how these concurrent conditions may influence psoriasis treatment outcomes.Objectives To assess NCD prevalence and their influence on psoriasis treatment outcomes.Methods From 2022 to 2024, we recruited psoriasis patients in Shanghai Skin Disease Hospital. Data on demographic features, NCD comorbidities and treatment outcomes at week 4 and week 8 were systematically collected th

Psoriasis has been successfully treated by directly blocking the interleukin (IL)-23/IL-17 pathway and several inhibitors that specifically target the IL-23/IL-17 signaling axis have been approved by the Food and Drug Administration for clinical use and show excellent efficacy. However, all the approved IL-23/IL-17 axis targeting agents cannot be non-invasively delivered as topical treatment due to their biological and physicochemical properties, e.g., susceptibility to degradation, large molecu

Psoriasis is an immune-mediated chronic inflammatory disease. Increasing evidence suggests a close association between ribosome biogenesis (RiboSis) and the pathogenesis of psoriasis. However, the precise mechanisms remain unclear. We first obtained bulk transcriptome and single-cell RNA sequencing datasets from the GEO database. Subsequently, differential expression analysis (DEG) and weighted gene co-expression network analysis (WGCNA) were performed, preliminarily identifying 11 candidate bio

Abstract Objective To explore the clinical application value of Neutrophil extracellular traps (NETs) in evaluating psoriasis. Methods 2ml peripheral blood of 63 patients with psoriasis and 27 healthy controls were collected. Neutrophils were isolated by density gradient method, and the formation of NETs was observed by immunofluorescence staining. We then calculated the proportion and fluorescence intensity of NETs and analyzed their correlation with clinical classification, severity, and se

Immune-mediated inflammatory diseases (IMIDs), such as psoriasis, psoriatic arthritis, and inflammatory bowel disease, encompass a heterogenous group of conditions associated with chronic inflammation. Systemic treatments for patients with IMIDs include parenterally delivered monoclonal antibodies (mAbs) that disrupt specific cytokine and cytokine receptor binding interactions, and orally delivered small molecules that inhibit certain enzymes involved in the regulation of inflammatory signaling.

Introduction The German national psoriasis registry PsoBest collects long-term data on the effectiveness, safety, and tolerability of systemic treatments for psoriatic disease. Here, we describe patient characteristics and the safety and effectiveness of apremilast for the treatment of psoriatic disease in Germany based on data from PsoBest.Methods This was a descriptive analysis of observational data collected from PsoBest using cross-sectional (baseline characteristics) and longitudinal (outco

Background Nail psoriasis (NP) is not an uncommon psoriasis variant whose symptoms have a negative impact on patients' quality of life. Treating NP can be a great challenge for the dermatologist, especially when it is presented as isolated subtype or when it is not associated with psoriatic arthritis (PsA). The available treatments, topical or systemic therapies, have limited efficacy and can be associated with adverse effects (AEs). Topical roflumilast is an FDA-approved treatment for skin plaq

Psoriasis is a complex inflammatory autoimmune skin illness that causes epidermal keratinocyte hyperproliferation and dedifferentiation. In a previous study we did in the lab, we found that treating human keratinocytes (HaCaT) with PUVA increased the expression of hsa-miR-718 compared to control. In this study, an imiquimod (IMQ)-induced mouse model and HaCaT were used to look at how overexpressing miR-718 could help treat psoriasis and its causes. To gain more understanding, the in vivo study u
