Purpose: Psoriasis vulgaris, one of the most prevalent chronic inflammatory skin diseases, is associated with metabolic syndrome (MetS). Autophagy, an intracellular degradation system is essential for cell survival and differentiation, and its dysfunction may contribute to metabolic diseases. A cross-sectional study was conducted on 38 psoriasis vulgaris patients and 16 healthy control subjects to 1) Assess immunohistochemical (IHC) expression of microtubule-associated protein light chain 3 (LC3); 2) Evaluate the relationship between Psoriasis Area Severity Index (PASI) score, and LC3 expression.

Patients And Methods: PASI score was evaluated for all psoriasis patients. Lipid profile, blood sugar, and CRP were done for all patients and controls. A punch biopsy was taken from lesional and perilesional skin of psoriasis patients and normal skin of the controls. Tissue sections were prepared. IHC LC3 staining was done and evaluated.

Results: LC3 was nearly absent, in the epidermis of the lesional skin of psoriasis while it was strong among control (p=0.001). LC3 expression in the lesional skin of psoriasis vulgaris was lower than its expression in perilesional (p=0.001). However, LC3 expression was not significantly changed with PASI or the presence/absence of MetS.

Conclusion: A potential link between psoriasis vulgaris and autophagy as assessed by LC3 could be present. LC3 was down-regulated in psoriasis lesions than in normal skin. However, its expression did not change with PASI or MetS. An autophagy enhancer might be used as a possible therapeutic target in psoriasis vulgaris patients.

Background: Exosomes are extracellular vesicles, composed of a phospholipid bilayer, that are primarily derived from stem cells. The contents of exosomes can be incorporated into the tissue in which they are introduced, which presents a unique therapeutic option.

Aims: Exosomes have been investigated as a treatment for a number of medical ailments, but the literature supporting these indications is inconclusive.

Blood-based extracellular matrix (ECM) fragments have been identified as potential pharmacologic biomarkers in spondyloarthritis and diagnostic biomarkers in psoriatic arthritis and psoriasis vulgaris. This study aimed to explore whether ECM fragments can differentiate patients with psoriasis from healthy controls (HC) and determine their potential as biomarkers for response to treatment in psoriasis. The study population included 59 patients with moderate to severe psoriasis, not receiving systemic anti-psoriatic treatment at inclusion, and 52 HC matched by age, sex, and BMI.

Erythrodermic psoriasis (EP) is a life-threatening variant of psoriasis. In this study, we contrasted the vascular endothelial cells (ECs) in EP lesions against those in psoriasis vulgaris and healthy controls. Utilizing single-cell RNA sequencing, immunofluorescence, and flow cytometry on human and mouse samples, we observed a marked increase and activation of EP ECs, which upregulated genes relative to angiogenesis, leukocyte adhesion and antigen presentation.

Nanocrystals in Dermal Drug Delivery: A Breakthrough for Enhanced Skin Penetration and Targeted Skin Disorder Treatments.

Pharmaceutics

Department of Pharmaceutical Sciences, College of Clinical Pharmacy, King Faisal University, Al-Ahsa 31982, Saudi Arabia.

One of the major challenges in dermal drug delivery is the adequate penetration of the active compound into the skin without causing any skin irritation and inflammation. Nanocrystals (NCs) are nanoscale particles, and their sizes are below 1000 nm. NCs are made up of drug particles only, which are used to improve the aqueous solubility and bioavailability of poorly water-soluble drugs.
