The neuropeptide galanin is distributed in the central and peripheral nervous systems and in non-neuronal peripheral organs, including the skin. Galanin acts via three G protein-coupled receptors which, except galanin receptor 1, are expressed in various skin structures. The galanin system has been associated with inflammatory processes of the skin and of several other organs. Psoriasis is an inflammatory skin disease with increased neo-vascularization, keratinocyte hyperproliferation, a pro-inflammatory cytokine milieu, and immune cell infiltration...

BACKGROUND: Psoriasis is associated with risk of cardiovascular (CV) disease (CVD) and a major adverse CV event (MACE). Whether psoriasis duration affects risk of vascular inflammation and MACEs has not been well characterized. OBJECTIVES: We utilized two resources to understand the effect of psoriasis duration on vascular disease and CV events: (1) a human imaging study and (2) a population-based study of CVD events. METHODS: First, patients with psoriasis (N = 190) underwent fludeoxyglucose F 18 positron emission tomography/computed tomography (duration effect reported as a β-coefficient)...

Adipokines are secreted by white adipose tissue, an active endocrine organ, and play a role in the regulation of metabolic functions such as lipid metabolism, inflammation, and vascular homeostasis. Adipokines are secreted in excess in obesity and contribute to the development of associated comorbidities such as metabolic syndrome and atherosclerosis. Psoriasis, a chronic immune-mediated skin disease, is associated with obesity and increased cardiovascular risk. Understanding the role of adipokines in psoriasis may in part explain the association between psoriasis and cardiovascular disease...

BACKGROUND: Hyperkeratinization is a major cause of obstructive meibomian gland dysfunction (oMGD) and results in degenerative gland dilation and atrophy without inflammation. Ointment containing 1,25-dihydroxy-22-oxavitamin D3 (maxacalcitol), a noncalcemic analog of the active form of vitamin D3, is applied for the treatment of hyperkeratotic cutaneous conditions such as psoriasis and ichtyosis because it suppresses the proliferation and promotes the differentiation of keratinocytes through interaction with the vitamin D receptor...

Importance: Inflammation is critical in the development of atherosclerosis. Psoriasis is a chronic inflammatory skin disease that is associated with increased vascular inflammation by 18fluorodeoxyglucose positron emission tomography/computed tomography in vivo and future cardiovascular events. It provides a human model to understand the effect of treating inflammation in a target organ (eg, the skin) on vascular diseases. Objective: To investigate the association between change in skin disease severity and change in vascular inflammation at 1 year and to characterize the impact of 1 year of anti-tumor necrosis factor therapy on vascular inflammation...

There is substantial evidence implicating the urokinase system in tissue remodeling during neo-vascularization, inflammation, tumor invasion, and metastasis. Regulated degradation of the extracellular matrix at the leading edge of migrating cells, mediated by uPA and uPAR, is required for tissue remodeling, invasiveness, and angiogenesis. Psoriasis and basal cell carcinoma (BCC) are the most common skin diseases. Pathogenesis of both of them is associated with keratinocyte hyperproliferation, inflammatory cell migration, and angiogenesis-processes in which the plasminogen system (uPA, uPAR, tPA, and PAI-1) plays a crucial role...

Vascular inflammation is increased in patients with psoriasis. This randomized, double-blind, multicenter study evaluated the effects of tumor necrosis factor-α antagonist adalimumab on vascular inflammation in patients with psoriasis. A total of 107 patients were randomized (1:1) to receive adalimumab for 52 weeks or placebo for 16 weeks followed by adalimumab for 52 weeks. Vascular inflammation was assessed with positron emission tomography-computed tomography. There were no differences in the change from baseline in vessel wall target-to-background ratio (TBR) from the ascending aorta (primary endpoint) (adalimumab: TBR = 0...

OBJECTIVES: To characterize the T cell subsets producing interleukin 17 (IL-17) isoforms A and F in hypertensive kidneys and vessels and determine whether inhibition of IL-17 signaling lowers blood pressure and end-organ damage in a mouse model of hypertension. BACKGROUND: T cell derived cytokines play a central role in the pathophysiology of hypertension and contribute to end-organ dysfunction. We previously showed that mice genetically deficient in IL-17A exhibited blunted hypertension and reduced renal and vascular dysfunction in response to angiotensin II (Ang II) infusion...

Inflammation is known to play a significant role in the process of atherogenesis and cardiovascular disease (CVD). Indeed, patients with chronic inflammatory diseases are at increased risk for cardiovascular events. However, the mechanisms linking chronic inflammation and CVD remain poorly understood. Psoriasis, a chronic inflammatory skin disease associated with a greater risk of early cardiovascular events, provides a suitable human model to study the pathophysiology of inflammatory atherogenesis in humans...

Angiogenesis is the growth of new blood vessels from pre-existing vessels. It is a biological process essential in physiological wound healing or pathological inflammation and tumor growth, which underlies a complex interplay of stimulating and inhibiting signals. Extracellular matrix, cells of innate and adaptive immunity and endothelial cells itself are a major source of angiogenic factors that activate or inhibit specific receptors and consequently influence intracellular signaling pathways. Most inflammatory and neoplastic diseases in dermatology are characterized by excessive angiogenesis, such as psoriasis, atopic dermatitis, as well as melanoma, non-melanoma skin cancer, but also benign vascular neoplasia...

Psoriasis is a chronic skin disease also affecting other sites such as joints. This disease highly depends on inflammation and angiogenesis as well as other pathways. At each step of the psoriasis molecular pathway, different inflammatory cytokines and angiogenic growth factors are involved such as hypoxia inducible factor-1 α (HIF-1 α), vascular endothelial growth factor (VEGF), matrix metalo proteinases (MMPs), basic fibroblast growth factor (bFGF), Angiopoitin-2, interleukin-8 (IL-8), IL-17, and IL-2. Beside the mentioned growth factors and cytokines, cellular adhesion molecule 1 (ICAM-1) and vascular cell adhesion molecule-1 (VCAM-1) which play roles in both angiogenesis and inflammation are also involved in the pathogenesis...

Cellular senescence is characterized by a permanent cell-cycle arrest and a pro-inflammatory secretory phenotype, and can be induced by a variety of stimuli, including ionizing radiation, oxidative stress, and inflammation. In endothelial cells, this phenomenon might contribute to vascular disease. Plasma levels of the inflammatory cytokine tumor necrosis factor alpha (TNFα) are increased in age-related and chronic conditions such as atherosclerosis, rheumatoid arthritis, psoriasis, and Crohn's disease. Although TNFα is a known activator of the central inflammatory mediator NF-κB, and can induce the intracellular generation of reactive oxygen species (ROS), the question whether TNFα can induce senescence has not been answered conclusively...

INTRODUCTION: Psoriasis is an immune-mediated chronic inflammatory dermatosis. Several studies have shown that patients with psoriasis have a much greater risk of cardiovascular diseases than the normal population. The chronic inflammation observed in psoriasis is thought to have a role in the development of atherosclerosis and vascular endothelial injury. AIM: To examine serum pregnancy-associated plasma protein-A (PAPP-A) levels, which has been regarded as a marker of early stage atherosclerosis in patients with psoriasis that do not have concurrent conventional cardiovascular risk markers...
