The therapeutic efficacy of mesenchymal stem cells and their extracellular vesicles in the treatment of diverse skin diseases.

This review presents the current knowledge on the potential of mesenchymal stem cells (MSCs) and their extracellular vesicles (EVs) in the treatment of various skin diseases such as psoriasis, atopic dermatitis, contact dermatitis, systemic sclerosis, graft-versus-host disease, alopecia areata, and systemic lupus erythematosus. MSCs can modulate the immune response and release growth factors and cytokines that promote tissue regeneration and healing and reduce inflammation. In turn, EVs' ability to transport various biological molecules, including microRNAs (miRNAs), makes them potential therapeutic agents.

The Role of Selected Proteins in the Pathogenesis of Psoriasis.

Psoriasis is a chronic, immune-mediated inflammatory skin disease with complex genetic, environmental, and immunological determinants. Beyond the skin, it affects multiple systems, including the joints and cardiovascular system. A hallmark of psoriasis is an overactivation of the innate and adaptive immune responses, leading to dysregulated cytokine signaling, altered keratinocyte function, and aberrant expression of structural and regulatory proteins.

Psoriasis in Obese Adolescents with Diabetes-From Common Molecular Background to Vicious Circle of Metabolic Syndrome-Case Report and Review of Literature.

Psoriasis and type 1 diabetes mellitus (T1DM) are chronic autoimmune diseases sharing common immunological pathways, particularly the involvement of interleukin 17 (IL-17), driving Th17-mediated inflammation. This review explores the overlap between psoriasis, obesity, T1DM, and necrobiosis lipoidica (NL), a skin condition associated with diabetes. Obesity exacerbates inflammation through immune cell activation in adipose tissue and the release of proinflammatory adipokines, such as leptin, resistin, and IL-18, which enhance autoimmune responses and insulin resistance.

Apolipoproteins in Psoriasis: The Effect of Acitretin Treatment and UVB Phototherapy.

Background: Psoriasis is a chronic, multi-system inflammatory disease frequently associated with metabolic syndrome and lipid disturbances. Apolipoproteins, as essential regulators of lipid metabolism, may play a critical role in these metabolic abnormalities, potentially influencing disease severity and systemic inflammation. The aim of this study was to compare serum concentrations of chosen apolipoproteins in patients with psoriasis before and after treatment with acitretin or narrowband UVB (NB-UVB).

An Overview of Growth Factors as the Potential Link between Psoriasis and Metabolic Syndrome.

Psoriasis is a chronic, complex, and immunologically mediated systemic disease that not only affects the skin, but also the joints and nails. It may coexist with various other disorders, such as depression, psoriatic arthritis, cardiovascular diseases, diabetes mellitus, and metabolic syndrome. In particular, the potential link between psoriasis and metabolic syndrome is an issue worthy of attention.

Crosstalk between Serum and Skin Sphingolipids in Psoriasis.

Psoriasis is a chronic, complex, immunological disorder, which may lead to many different systemic complications. Sphingolipids, including ceramide, are bioactive lipids, which take part in the regulation of immune reactions, cell growth, and apoptosis. Twenty psoriatic patients and twenty-eight control subjects were included in the study.

The Interplay between Bioactive Sphingolipids in the Psoriatic Skin and the Severity of the Disease.

Psoriasis is a complex chronic immunologically mediated disease that may involve skin, nails, and joints. It is characterized by hyperproliferation, deregulated differentiation, and impaired apoptosis of keratinocytes. Sphingolipids, namely ceramide, sphingosine-1-phosphate, sphingosine, sphingomyelin, and sphinganine-1-phosphate, are signal molecules that may regulate cell growth, immune reactions, and apoptosis.

Effects of Hypolipidemic Drugs on Psoriasis.

Psoriasis is a chronic, systematic, inflammatory disease in which multiple metabolic and immunologic disturbances lead to lipid abnormalities, impaired glucose tolerance, metabolic syndrome, diabetes mellitus, atherosclerosis, hypertension, ischemic heart disease, and numerous metabolic disorders. In clinical practice, the most commonly used drugs in the treatment of lipid abnormalities are statins and fibrates. Statins are characterized by pleiotropic effects such as antioxidant, anti-inflammatory, anticoagulant, and antiproliferative.

The Role of Sphingolipids in the Pathogenesis of Psoriasis.

Psoriasis is a complex, chronic, immunologically mediated disease which involves skin and joints. Psoriasis is commonly connected with numerous other diseases such as liver diseases, metabolic syndrome, impaired glucose tolerance, diabetes mellitus, atherosclerosis, hypertension, and ischemic heart disease. Interestingly, comorbidities of psoriasis are an attention-grabbing issue.

The study included 70 patients with adrenal tumors divided into three subgroups: incidentaloma ( = 30), pheochromocytoma ( = 20), and Cushing's/Conn's adenoma ( = 20), as well as 60 healthy controls. Blood and urine samples were collected before elective endoscopic adrenalectomy.

Serum fatty acid binding protein 5 (FABP5) as a potential biomarker of inflammation in psoriasis.

Fatty acid binding protein 5 (FABP5) is elevated in psoriatic keratinocytes and could be involved in systemic metabolic disturbances in psoriasis. The aim of the study was to evaluate serum FABP5 in obese and non-obese psoriatic patients, to assess the relationship between FABP5 and the duration, severity of the disease, inflammatory and metabolic markers and influence of treatment with narrowband-ultraviolet B (NB-UVB). Seventy-four patients (30 treated with NB-UVB) with psoriasis were enrolled in the study.

Sirtuin 1 and Skin: Implications in Intrinsic and Extrinsic Aging-A Systematic Review.

Skin, as the outermost organ of the body, is constantly exposed to both intrinsic and extrinsic causative factors of aging. Intrinsic aging is related to compromised cellular proliferative capacity, and may be accelerated by harmful environmental influences with the greatest significance of ultraviolet radiation exposure, contributing not only to premature aging, but also to skin carcinogenesis. The overall skin cancer burden and steadily increasing global antiaging market provide an incentive for searching novel targets to improve skin resistance against external injury.
