Noninvasive Tape-Stripping with High-Resolution RNA Profiling Effectively Captures a Preinflammatory State in Nonlesional Psoriatic Skin

Lam C. Tsoi et al.

Summary: This study demonstrates that tape stripping with optimized high-resolution transcriptomic profiling can effectively assess and characterize inflammatory responses in the skin. By comparing different samples and sampling methods, the study shows that tape stripping can capture the transcriptome of the upper layers of the skin, providing insights into the molecular components of the immune amplification pathway in psoriasis. Additionally, the study suggests that nonlesional psoriatic skin exhibits activated, proinflammatory changes, which are not captured by full-thickness skin biopsy transcriptome profiling.

Therapy of psoriasis during pregnancy and breast-feeding

Galina Balakirski et al.

Summary: In the last decade, multiple systemic drugs have been approved for the treatment of psoriasis vulgaris and psoriasis arthritis (PsA). However, treatment decisions for women planning a pregnancy, as well as pregnant and lactating women, are challenging due to limited data. Topical corticosteroids have the strongest evidence for psoriasis therapy during pregnancy. Medically controlled use of UVB-therapy is also considered safe. TNF-alpha inhibitors have the best evidence for systemic therapy during pregnancy and lactation. Personalized therapeutic approaches should be based on the severity of psoriasis and patient's comorbidities.

Summary: This study conducted a meta-analysis of publicly available gene expression datasets to examine the differential expression observed in response to anti-TNF alpha therapy in psoriasis, inflammatory bowel disease, and rheumatoid arthritis. The results identified distinct pro-inflammatory down-regulated genes for each disease and common inflammatory patterns involved in the pathogenesis of each disease.

Enhanced Migratory Ability of Neutrophils Toward Epidermis Contributes to the Development of Psoriasis via Crosstalk With Keratinocytes by Releasing IL-17A

Xiu-ting Liu et al.

Summary: Microabscess of neutrophils in epidermis is a histological hallmark of psoriasis. This study found that blood neutrophils were increased in psoriasis patients, positively correlated with disease severity, and highly expressed CD66b. Keratinocytes expressed high levels of psoriasis-related inflammatory mediators through interaction with neutrophils, and this interaction was dependent on IL-17A produced by neutrophils. Neutrophils from psoriasis patients displayed more transcriptome changes related to integrin and increased migration capacity toward keratinocytes.

Comparison of transcriptomic profiles in edge to center of plaque reveals chronological molecular events in psoriatic plaque formation

Suphagan Boonpethkaew et al.

Summary: This study compared the gene profiles in the peripheral edge (PE) and center (CE) of plaques to elucidate the chronological molecular events in plaque formation. Inflammation is likely initiated in the PE, characterized by the presence of specific molecules such as IL-36 alpha, S100A7, and S100A15. The inflammatory state progresses towards a more stable state in the CE, where growth factor activities are increased, potentially leading to the regression of inflammation. These findings contribute to the development of novel therapies for psoriasis.

COVID-19 vaccine safety and efficacy in patients with immune-mediated inflammatory disease: Review of available evidence

Sarah Wack et al.

Summary: This review explores the safety and efficacy of COVID-19 vaccines in patients with immune-mediated inflammatory diseases (IMID), indicating that these patients are not at a greater risk of harm from vaccination compared to healthy controls. Most patients with IMID will benefit from vaccination to prevent severe COVID-19, although it remains to be seen if patients on biologics will generate a sufficient immune response to the vaccine.

Epigenetics in psoriasis: perspective of DNA methylation

Ying Luo et al.

Summary: Psoriasis is a chronic inflammatory skin disease with genetic, immune, and environmental factors playing a role in its onset. DNA methylation, as an epigenetic modification, is involved in the pathogenesis of psoriasis, regulating target genes that have been validated indirectly or directly. Understanding the role of DNA methylation in psoriasis comprehensively will aid in diagnostic and therapeutic strategies for psoriatic patients.

Role of Janus Kinase Inhibitors in Therapy of Psoriasis

Sylwia Sluczanowska-Glabowska et al.

Summary: Janus kinase inhibitors target JAK/STAT pathway to reduce inflammation in inflammatory and autoimmune diseases. Divided into first and second generations, with second generation being more specific. Oral JAK inhibitors show promise in psoriasis treatment.

Molecular Pathogenesis of Psoriasis and Biomarkers Reflecting Disease Activity

Masaru Honma et al.

Summary: Psoriasis is a chronic inflammatory skin disease with bothersome symptoms, but recent advances in molecular-targeted therapies have shown promising clinical effects in treating severe symptoms and related skin diseases. Biomarkers such as cytokines, chemokines play a crucial role in defining therapeutic strategies, and blood protein markers show great potential in daily clinical practice.

Therapeutic Development Based on the Immunopathogenic Mechanisms of Psoriasis

Jen-Chih Tseng et al.

Summary: Psoriasis is a complex inflammatory autoimmune skin disorder affecting 2-3% of the global population, mainly influenced by genetic and environmental factors, with current treatments focusing on immune responses. While biologics have shown better efficacy and safety in alleviating symptoms, psoriasis remains incurable.

Systematic Review and Recommendations to Combine Newer Therapies With Conventional Therapy in Psoriatic Disease

Sandeep Arora et al.

Summary: Combining different therapies for psoriasis, including newer and conventional agents, based on evidence from literature can improve efficacy and reduce toxicity of higher dosages, providing therapeutic guidelines for better management of the disease.

Pediatric Psoriasis: From New Insights into Pathogenesis to Updates on Treatment

Hye One Kim et al.

Summary: Psoriasis is a chronic inflammatory systemic disease that primarily affects the skin, with one-third of cases starting in childhood. Pediatric psoriasis has unique clinical characteristics, but treatment usually involves methods similar to adults. Research on pediatric psoriasis is lacking, and targeted therapies using newly developed biologics are increasingly being applied.

Biomarkers predictive of treatment response in psoriasis and psoriatic arthritis: a systematic review

Conor Magee et al.

Summary: The current study indicates that some biomarkers may be associated with treatment response in psoriatic disease, however, due to the diversity in research methods and outcomes, firm conclusions cannot be drawn and further validation is needed.

Skin-Resident Memory T Cells: Pathogenesis and Implication for the Treatment of Psoriasis

Trung T. Vu et al.

Summary: Tissue-resident memory T cells (T-RM) remain in peripheral tissues for long periods, providing the first line of adaptive immune response. Skin T-RM play a significant role in chronic inflammatory skin diseases, such as psoriasis, where IL-17A-producing CD8(+) T-RM are considered pathogenic. Targeting skin T-RM could be a potential strategy in treating psoriasis.
