Paeonol, an active component derived from the traditional Chinese medicine Cortex Moutan, possesses anti-inflammatory, analgesic, antioxidant and anti-allergic properties. Psoriasis is a chronic, recurrent, inflammatory dermatosis accompanied by excessive activation of Toll‑like receptors (TLRs) in dendritic cells (DCs), which are primarily responsible for initiating an immune response. We investigated the effect of paeonol on inflammation in an imiquimod (IMQ)-induced psoriasis-like mouse model and murine bone marrow-derived dendritic cells (BMDCs) stimulated by R848...

Psoriasis is a chronic inflammatory skin disorder that affects 2% of the population. Evidence suggests that interleukin (IL)-23 plays a pivotal role in the pathogenesis of psoriasis. Guselkumab is a subcutaneously administered, humanized anti-IL23 monoclonal antibody indicated for the treatment of moderate-to-severe plaque psoriasis. Data from Phase I-III trials in this patient population reveal that guselkumab has proven to be superior to placebo or adalimumab based on achieving a Psoriasis Area and Severity Index (PASI) 90% reduction, or a static Physician Global Assessment (sPGA) score of 0 or 1 from baseline...

BACKGROUND: Ustekinumab is a monoclonal antibody targeting interleukins 12 and 23. While effective in clinical trials for Crohn's disease (CD), long-term maintenance of response in the real-world setting is unclear. We aim to assess the efficacy of ustekinumab for maintaining clinical, endoscopic, and radiographic response in CD. METHODS: A retrospective multicenter cohort study was performed on patients with CD achieving steroid-free clinical response to ustekinumab induction, and advanced onto a regularly scheduled maintenance ustekinumab regimen between 2011 and 2016...

A patient with leukocyte adhesion deficiency type 1 (LAD1) had severe periodontitis and an intractable, deep, nonhealing sacral wound. We had previously found a dominant interleukin-23-interleukin-17 signature at inflamed sites in humans with LAD1 and in mouse models of the disorder. Blockade of this pathway in mouse models has resulted in resolution of the immunopathologic condition. We treated our patient with ustekinumab, an antibody that binds the p40 subunit of interleukin-23 and interleukin-12 and thereby blocks the activity of these cytokines, inhibiting interleukin-23-dependent production of interleukin-17...

Pityriasis rubra pilaris (PRP) represents a group of rare chronic inflammatory skin disorders in which ~1 in 20 affected individuals show autosomal dominant inheritance. In such cases, there may be gain-of-function mutations in CARD14, encoding caspase recruitment domain-containing protein 14 (CARD14) that activates the non-canonical nuclear factor-kappa B (NF-κB) pathway, thereby promoting cutaneous inflammation. Here, we report a mother and son with PRP due to a new missense mutation in CARD14 and describe the beneficial clinical effects of ustekinumab, a monoclonal antibody against interleukins-12 and -23, in both subjects...

The use of monoclonal antibodies against interleukin (IL)-12 and -23, such as ustekinumab, has considerably reduced the disease burden in many patients with moderate to severe psoriasis. Reversible posterior leukoencephalopathy syndrome (RPLS) is a neurologic disorder that has been documented with increased frequency with the use of systemic and biologic agents. We report a case of a 58-year-old man with psoriasis who presented with confusion and memory difficulties after being on treatment with ustekinumab for over six years...

The interleukin (IL)-23/IL-17 axis is strongly implicated in the pathogenesis of psoriasis. Previous studies showed that IL-18 was elevated in early active and progressive plaque-type psoriatic lesions and that serum or plasma levels of IL-18 correlated with the Psoriasis Area and Severity Index. However, the mechanism whereby IL-18 affects disease severity remains unknown. In this study, we investigated the effects of IL-18 on a psoriasis-like skin inflammation model induced by recombinant mouse IL-23. We found that IL-18, cooperatively with IL-23, induced prominent inflammation and enhanced psoriasis-like epidermal hyperplasia...

Research findings over the past several decades have shown that inflammation is a prominent feature of many chronic diseases, with poor diet being one likely inflammatory stimulus. Specifically, a single high-fat meal (HFM) has been suggested to increase inflammation, although there is currently no consensus with regard to the specific changes in many of the proinflammatory markers that are frequently assessed after an HFM. The aim of this systematic review was to objectively describe the postprandial timing and magnitude of changes in 5 common inflammatory markers: interleukin (IL) 6, C-reactive protein (CRP), tumor necrosis factor (TNF) α, IL-1β, and IL-8...
