Angiopoietins/Tie2 signaling axis and its role in angiogenesis of psoriasis.

Acta Histochem

Hyperplasia of microvessels in the superficial dermis is the main pathological feature of psoriasis, and is linked to the pathogenesis of psoriasis. Thus, anti-angiogenic therapy may be effective for psoriasis. Angiopoietins (Angs) are crucial angiogenic factors.

Psoriasis is an autoimmune-driven inflammatory skin disease, clinically characterized by skin thickening, erythema, and scaling, significantly impacting patients' life quality and mental health. Clinically, oral pill or injection of methotrexate (MTX) formulation is a common route for psoriasis therapy, while both methods often cause undesired toxicity due to systemic administration, and limit patient compliance because of the frequent-dosing requirement. Here, we introduce a dissolvable microneedle (MN) patch made of polyvinyl alcohol (PVA) that incorporates self-assembled hyaluronic acid (HA) nanoparticles (NPs) conjugating MTX, which is designed for treating skin diseases, offering reduced adverse effects and improved patient adherence through its targeted and long-acting properties.

IWR-1 attenuates the promotional effect of IL-36γ in a mouse model of psoriasis.

BMC Immunol

November 2024

Department of Dermatology, State Key Laboratory of Complex Severe and Rare Diseases, Peking Union Medical College Hospital, Chinese Academy of Medical Science and Peking Union Medical College, No.1 Shuaifuyuan Dongcheng District, Beijing, China.

Background: Psoriasis is a chronic inflammatory skin disease. The Wnt/β-catenin signaling pathway is essential for the regulation of adult stem cells, homeostasis, and tissue regeneration; however, the relationship between this pathway and interleukin (IL)-36γ in the pathogenesis of psoriasis remains unclear.

Methods: In this study, psoriasiform model mice were established using imiquimod (IMQ) induction.

Psoriasis is a chronic T-cell-mediated autoimmune skin disorder characterized by excessive epidermal thickening, overproliferation of keratinocyte, disruption of epidermal cell differentiation, and increased blood vessel growth in the dermal layer. Despite the common use of corticosteroids in psoriasis treatment, their limited efficacy and numerous side effects pose significant challenges. This research introduces a promising alternative approach by encapsulating eugenol (EU) in soya phosphatidylcholine (SPC) nanoparticles (EUNPs) which showed spherical shape nanoparticles with a hydrodynamic size of approximately 200 nm, polydispersity index 0.

Department of Critical Care Medicine and Neurosurgery of Huashan Hospital, State Key Laboratory of Medical Neurobiology and MOE Frontiers Center for Brain Science, Institutes of Brain Science, Fudan University, Shanghai 200032, China. Electronic address:

Psoriasis, a chronic autoimmune skin condition with significant global morbidity, badly impairs patients' quality of life. Stress has been identified as a prominent trigger for psoriasis, and effectively management of stress can ameliorate its pathological manifestations. However, the precise mechanisms by which stress influences psoriasis remain elusive.
