Adipokines modulate immune responses and lipid metabolism in allergic disease; however, little is known about its role in the skin barrier and atopic dermatitis (AD). We identified zinc-alpha-2 glycoprotein (ZAG), an adipokine that regulates lipid mobilization, as a biomarker for AD. ZAG levels were consistently decreased in sera, T cells, and skin in human AD patients compared with healthy controls. ZAG was primarily detected in the stratum corneum along with filaggrin (FLG) and loricrin (LOR). Knockdown of ZAG with shRNA resulted in decreased FLG and increased thymic stromal lymphopoietin (TSLP)...

BACKGROUND: Vitiligo is a chronic skin disorder presenting with depigmentation, the pathogenesis of which is complex but the autoimmune theory is now preferred. Multiple immunologic processes, including stimulation of the T-helper (Th)1 response, formation of autoreactive melanocyte-specific CD8+ T lymphocytes, a decrease in the blood concentration of T regulatory (Treg) cells, and an increase in interleukin (IL)-17 and interferon (IFN) concentration, have been shown to contribute to vitiligo progression and maintenance...

It has been proven that hepatitis C virus (HCV) eradication after interferon-based treatment can reduce the risk of hepatocarcinogenesis. However, there were some arguments about whether the treatment of direct-acting antivirals (DAAs) boosts the development of hepatocellular carcinoma (HCC). We systematically review this crucial topic by combining all the relevant articles to calculate the pooled HCC density after DAA treatment. Studies reporting the recurrence or occurrence in chronic hepatitis C patients who received DAA regimen were selected from three retrieval library screening...

Over the last few decades, the improved diagnostic criteria, the wide use of MRI, and the growing availability of effective pharmacologic treatments have led to substantial advances in the management of multiple sclerosis (MS). The importance of early diagnosis and treatment is now well-established, but there is still no consensus on how to define and monitor response to MS treatments. In particular, the clinical relevance of the detection of minimal MRI activity is controversial and recommendations on how to define and monitor treatment response are warranted...

BACKGROUND: Alopecia areata (AA) is associated with Interferon- γ (IFN-γ) mediated T-lymphocyte dysfunction and increased circulating Interleukine-17 (IL-17) levels. Epigallocatechin-3-gallate (EGCG) specifically inhibits IFN-γ pathways and unlike Janus Kinase 1 and 2 (JAK1/JAK2) inhibitors (tofacitinib, ruxolitinib), EGCG is safer, more cost-effective, and is a topically active agent. Our objective is to test the mode of action of EGCG in vitro and ex vivo using HaCat, Jurkat cell lines, and peripheral blood mononuclear cells (PBMCs) of AA patients and healthy controls (HCs), respectively...

Primary biliary cholangitis (PBC) is an autoimmune liver disease with a striking female preponderance. The mechanisms behind this predominance are still to be elucidated, although multiple theories have been postulated and investigated. Among the proposed involved factors, sex hormones have been the first to be studied, but unfortunately data have been inconclusive or conflicting. Similarly, fetal microchimerism has received a huge attention in the past, but data in PBC have been unsatisfactory especially if compared to other autoimmune diseases like systemic lupus erythematosus...

INTRODUCTION: Peyronie's disease (PD) is a fibrotic disorder that leads to plaque formation in ∼3-9% of adult men. Connective tissue buildup results in plaque formation, penile curvature and shortening, and in some cases, pain. In the active phase of PD, penile pain is a common symptom, often accompanied by progression in curvature. Treatment options for PD include oral drugs, topical cream, intralesional injections, traction, and shock wave therapy. This article reviews the different treatment options for active-phase PD...

OBJECTIVE: Resolvins have been shown to attenuate inflammation, whereas NETosis, the process of neutrophils releasing neutrophil extracellular traps (NETs), produces increased inflammation. It is hypothesized that treatment of animals with resolvin D1 (RvD1) would reduce abdominal aortic aneurysm (AAA) formation by inhibiting NETosis. METHODS: Wild-type 8- to 12-week-old C57BL/6 male mice (n = 47) and apolipoprotein E-deficient (ApoE-/- ) mice (n = 20) were used in two models to demonstrate the effects of RvD1 on AAA growth...

Skin contains a large number of antigen presenting cells, making intradermal (ID) injection one of the most effective ways for vaccine administration. However, although current adjuvants may cause severe local reactions and inflammations in the skin, no adjuvant has been approved for ID vaccination so far. Here, we report that topical application of all- trans retinoic acid (ATRA), a vitamin A derivative produced in the human body, augmented cutaneous influenza vaccination. The adjuvant effects were evaluated in a murine vaccination/challenge model by using A/California/07/2009 pandemic vaccine (09V) or a seasonal influenza vaccine (SIV)...

A series of paediatric patients is presented in whom topical interferon alpha-2b was used as a co-adjuvant treatment for conjunctival papilloma. This condition is frequently associated with human papillomavirus infection. There is little information on the pediatric population with the use of interferon for the treatment of these lesions. In this case series, adjuvant treatment with topical interferon alpha-2b in paediatric patients showed no recurrence and good tolerance.

Atopic dermatitis (AD) is a chronic inflammatory skin disease characterized by complex symptoms. To treat AD without adverse effects, alternative therapeutic agents are required. The tubers of Helianthus tuberosus L. (Jerusalem artichoke) have been used in folk remedies for diabetes and rheumatism. However, its effect on AD development remains unknown. Therefore, this study examined the inhibitory effect of H. tuberosus (HT) on AD skin symptoms using an NC/Nga mouse model and HaCaT keratinocytes. The effect of HT and associated molecular mechanisms were evaluated in Dermatophagoides farina body (Dfb)-induced AD mice and tumor necrosis factor (TNF)-α/interferon (IFN)-γ-stimulated HaCaT keratinocytes by ELISA, western blot, and histological analysis...
