Psoriasis is a chronic, complex immune-mediated inflammatory disorder with cutaneous and systemic manifestations in which keratinocytes, dendritic cells and T cells have central roles. UBE2L3 may be a protective biomarker that regulates the pathogenesis of psoriasis. Here, we identify the IL-17A signaling similarity between human psoriatic skin and Ube2l3 conditional knockout mouse skin in the epidermis rather than dermis. IL-17A is regulated by CXCR6+ Vγ2+ γδT cells in mouse while CXCR6+ CD8+ T

Background Psoriasis is a chronic, immune-mediated, inflammatory skin disease characterized by abnormal keratinocyte proliferation, in which M1 macrophage polarization plays a critical role. However, the specific biomarkers and mechanisms underlying macrophage polarization in psoriasis remain unclear.Methods We analyzed the psoriasis dataset (GSE14905) to identify differentially expressed genes and applied weighted gene co-expression network analysis to identify key module genes.

Skin infiltration by neutrophils is a hallmark of the chronic inflammatory skin disease psoriasis, yet the mechanisms underlying neutrophil recruitment and positioning in chronically inflamed skin remain poorly understood. In this study, we demonstrate the significant impact of a total genetic deficiency of secretory leukocyte protease inhibitor (SLPI) on neutrophil migration in mouse skin. Without SLPI, neutrophils displayed an unconventional migratory pattern, characterized by altered interact

Psoriasis is an incurable and recurrent skin disease, and the need to develop new strategies for the treatment of psoriasis persists. Smilax glabra Roxb. (SGR) is listed as a key traditional Chinese medicine for the treatment of psoriasis through medicinal bath therapy in "Guideline for the diagnosis and treatment of psoriasis in China"; the active ingredients responsible for its anti-psoriatic effects and their mechanisms of action still require in-depth research. In this study, we first found

Background Psoriasis is an immune-mediated chronic inflammatory condition characterized by significant neutrophil infiltration in the skin. Given that the spleen is the largest peripheral immune organ in the body, it is important to investigate whether it has any impact on skin inflammation in psoriasis.Methods To investigate this mechanism, a psoriatic mouse model was established by IMQ application. Flow cytometry and immunohistochemistry analyses were performed to determine the percentage of v

Prolonged glucocorticoid therapy may lead to adrenal insufficiency (AI) or even adrenal crisis (AC) due to suppression of the hypothalamic-pituitary-adrenal (HPA) axis. This case report describes a male patient with psoriasis who had received long-term irregular glucocorticoid therapy for psoriasis management. Following an upper respiratory tract infection, the patient developed generalized skin lesions accompanied by systemic symptoms including abdominal pain, vomiting, fatigue, fever, and leth

Moderate to severe psoriasis has been reported as an independent risk factor for IgA nephropathy (IgAN). IgAN is characterized by episodic microscopic hematuria, which can progress to end-stage renal disease (ESRD). Managing therapeutic interventions for psoriasis patients requiring dialysis due to ESRD presents significant challenges. We present a case of severe plaque psoriasis in a patient concurrently diagnosed with IgAN who is dependent on hemodialysis. Over the past two months, his conditi

Psoriasis is a chronic skin disease characterized by keratinocyte hyperproliferation, epidermal hyperplasia, and immune cell infiltration involving both innate and adaptive immune systems. Bromodomain-containing protein 4 (BRD4), part of the Bromodomain and Extra-Terminal (BET) family, is implicated in various inflammatory and hyperproliferative disorders, though its role in psoriasis is unclear. This study investigates BRD4's role in psoriasis pathogenesis using BRD4-specific small interfering

Introduction SB17 is a ustekinumab (UST) biosimilar targeting interleukin-12/23 for treating immune-mediated inflammatory diseases (IMIDs). The development of UST biosimilars like SB17 may help address the high cost of innovator biologics, offering affordable alternatives without compromising efficacy or safety.Areas covered This review encompasses the totality of evidence supporting SB17's similarity to UST, its regulatory approval, and indication extrapolation. It also discusses SB17's lower i

Background/objectives Guttate psoriasis onset and plaque psoriasis flares are associated with streptococcal pharyngitis. Literature regarding the relationship between anogenital bacterial dermatitis and psoriasis in pediatric patients is limited. We aimed to evaluate the clinical characteristics, microbiology, and treatment course of patients with psoriasis/psoriasiform dermatitis and concomitant pharyngeal and/or anogenital bacterial infections.Methods A multicenter retrospective review of pati

Background The approach to pediatric psoriasis requires special considerations, given the potential for negative consequences on overall physical and psychosocial health.Objective The aim of this study was to systematically review the literature to characterize the burden of pediatric psoriasis.Methods Papers assessing associations between pediatric psoriasis (in children <18 years old) and quality of life, physical symptoms (e.g., skin pain, itch, sleep disruption), and adverse psychological

Background Psoriasis is a systemic immune disease associated with the development of various cancers. However, the causal nature of this association remains unclear. This study aims to systematically investigate the potential causal relationship between psoriasis and 32 types of cancer.Methods We utilized data from two large genomic databases, the UK Biobank and FinnGen, to extract GWAS summary statistics for 32 cancer types as outcomes and psoriasis-related data as exposures. Mendelian randomiz

Background Several traditional observational studies have reported an association between uveitis and psoriatic arthritis (PsA). However, the causal relationship between them remains unclear. Objective To investigate whether genetically predicted uveitis is related to the risk of PsA, and vice versa. Methods A two-sample bidirectional Mendelian randomisation (MR) design was employed, conducting a meta-analysis on data sourced from three distinct origins, followed by sensitivity analyses to ensur

Diabetes and psoriasis are known to increase the risk of each other, yet their combined impact on long-term mortality remains unclear. This prospective cohort study examined the associations between the coexistence of diabetes and psoriasis and all-cause and cause-specific mortality in a nationally representative sample of U.S. adults. Data were obtained from 16,852 participants in the National Health and Nutrition Examination Surveys (NHANES). Survival was assessed using the Kaplan-Meier method

Objective The concept of severity in psoriatic arthritis (PsA) remains inconsistently defined, often conflated with disease activity. This scoping review aimed to explore how severity has been defined in the PsA literature and to identify criteria used to characterize severe disease.Methods A scoping review was conducted in April 2025 following PRISMA-ScR guidelines. PubMed was searched for English-language articles from the last 25 years, alongside abstracts from major rheumatology conferences.

Introduction Psoriasis is a chronic immune-mediated skin disease with known physical and mental health comorbidities, such as cardiovascular disease, depression, and anxiety. Psoriasis also has a significant impact on quality of life and sleep due to factors like itch and pain. This study aims to assess the relationship between sleep quality, mental health, and psoriasis, and specifically investigate the impact of poor sleep quality on mental health outcomes within participants with psoriasis.Me

Objectives Psoriatic arthritis (PsA) increases cardiovascular disease risk. Emerging evidence suggests biologic Disease-Modifying Antirheumatic Drugs (DMARDs) may offer protective effects, though their advantage over conventional therapy remains under investigation.Methods A retrospective cohort study was conducted using the Chang Gung Memorial Research Database in Taiwan. Patients with PsA were identified from 2001 to 2022. The study included 2,383 patients who had used at least one disease-mod

In this commentary, we discuss the role of pharmacy benefit managers (PBMs) on access to biologics for patients with psoriasis. We highlight structural and system level barriers to biologics access, as well as how PBMs work as intermediaries between insurers, pharmacies, and drug manufactures to influence prescription formularies and generate health savings. We also discuss how controversial PBM practices such as step therapy, prior authorizations, and spread pricing may limit access to biologic

Psoriasis is an immune-mediated dermatosis characterized by systemic inflammation and multifactorial pathogenesis. Among its many triggers, psychological stress has emerged as a pivotal yet underappreciated contributor to disease onset and exacerbation. Although the pathomechanisms by which psychological stress is involved in the pathogenesis of psoriasis are not clear, evidence suggests a regulatory role of psychologic stress in immune functions, including increasing expression levels of proinf

Psoriasis, a common chronic inflammatory skin disease affecting approximately 2-3% of the global population, frequently co-occurs with depression. This highly prevalent comorbidity significantly impairs patients' quality of life. Despite the substantial physical and mental health burden imposed by psoriatic depression, the underlying pathophysiological mechanisms connecting psoriasis and depression remain poorly understood. In this review, we explored several pathological processes that may cont

Psoriasis is a chronic immune-mediated disease mainly affecting the skin with different clinical manifestations. As patients with psoriasis may also suffer from psoriatic arthritis and the skin lesions of psoriasis are disfiguring, their quality of life is often impaired. Many environmental and genetic factors have been implicated in psoriasis development. Currently, there is no cure for the disease and long-term drug treatment is usually necessary, especially in moderate to severe cases. Mesenc
