An Unusual Presentation of Lupus Vulgaris and the Practical Usefulness of Dermatoscopy.

Case Rep Dermatol Med 2018 14;2018:1036162. Epub 2018 Nov 14.

Specialist in Dermatology-Venereology, Chief of State Clinic of Dermatology, Hospital for Skin and Venereal Diseases, Delfon 124, 54643 Thessaloniki, Greece.

We report a case report of lupus vulgaris (LV) presented on the extremities of an 80-year-old man. He was misdiagnosed as having psoriasis and referred to our department for a second-opinion evaluation. The discrepancy between the clinical manifestation which was misleading and the dermatoscopic findings raised the suspicion of an underlying granulomatous disease and we proceeded to skin biopsy.

Dimethyl fumarate: Regulatory effects on the immune system in the treatment of multiple sclerosis.

J Cell Physiol 2018 Dec 7. Epub 2018 Dec 7.

Immunology Research Center, Tabriz University of Medical Sciences, Tabriz, Iran.

Dimethyl fumarate (DMF) is an important oral treatment option for various autoimmune diseases, such as multiple sclerosis (MS) and psoriasis. DMF and its dynamic metabolite, monomethyl fumarate (MMF) are the major compounds that exert therapeutic effects on several pathologic conditions in part, through downregulation of immune responses. The exact mechanism of DMF is yet to be fully understood even though its beneficial effects on the immune system are extensively studied. Read More

Neutrophil Extracellular Traps Induce Human Th17 Cells: Effect of Psoriasis-Associated TRAF3IP2 Genotype.

J Invest Dermatol 2018 Dec 5. Epub 2018 Dec 5.

Dermatology, University of Michigan, Ann Arbor, MI, United States; Ann Arbor Veterans Affairs Hospital, Ann Arbor, MI, United States. Electronic address:

Psoriasis lesions are rich in IL-17-producing T-cells as well as neutrophils, which release webs of DNA-protein complexes known as neutrophil extracellular traps (NETs). Because we and others have observed increased NETosis in psoriatic lesions, we hypothesized that NETs contribute to increased Th17 cells in psoriasis. After stimulating peripheral blood mononuclear cells (PBMCs) with anti-CD3/CD28 beads for 7 days, we found significantly higher percentages of CD3+CD4+IL-17+ (Th17) cells in the presence vs. Read More

Division of Rheumatology, Department of Internal Medicine, University of Michigan, Ann Arbor, MI 48109, USA. Electronic address:

Type I interferons (IFNs) are an immunomodulatory class of cytokines that serve to protect against viral and bacterial infection. In addition, mounting evidence suggests IFNs, particularly type I but also IFNγ, are important to the pathogenesis of autoimmune and inflammatory skin diseases, such as cutaneous lupus erythematosus (CLE). Understanding the role of IFNs is relevant to anti-viral responses in the skin, skin biology, and therapeutics for these IFN-related conditions. Read More

Nail Psoriasis: An Updated Review and Expert Opinion on Available Treatments, Including Biologics.

Acta Derm Venereol 2018 Dec 6. Epub 2018 Dec 6.

Department of Experimental, Diagnostic and Specialty Medicine, University of Bologna, Via Massarenti 1, IT-40138 Bologna, Italy.

Nail psoriasis affects 50-79% of patients with skin psoriasis and up to 80% of patients with psoriatic arthritis, and can also represent a negative prognostic factor in individuals with plaque psoriasis. Treatments for nail psoriasis are limited, as nails are often difficult to treat with topical therapies alone, and relapse is common. Among different systemic agents, secukinumab, a fully human monoclonal antibody targeting interleukin (IL)-17A, is the only antibody supported by a trial specifically conducted in patients with nail psoriasis (the TRANSFIGURE trial) and has the longest follow-up available to date.

Antibody-mediated delivery of VEGF-C potently reduces chronic skin inflammation.

JCI Insight 2018 Dec 6;3(23). Epub 2018 Dec 6.

VEGF-C is an important mediator of lymphangiogenesis and has been shown to alleviate chronic inflammation in a variety of disease models. In this study, we investigated whether targeted delivery of VEGF-C to sites of inflammation and site-specific activation of lymphatic vessels would represent a clinically feasible strategy for treating chronic skin inflammation. To this end, we generated a fusion protein consisting of human VEGF-C fused to the F8 antibody (F8-VEGF-C), which is specific for the alternatively spliced, angiogenesis-marking extradomain A (EDA) of fibronectin.

A Drug with Lipophilicity-Dependent Potency Can Be Metabolically Stable: Discovery of a Potent and Selective Retinoic Acid Receptor-Related Orphan Receptor C2 (RORC2) Inverse Agonist as an Orally Bioavailable Anti-Inflammatory Agent.

J Med Chem 2018 Dec 3. Epub 2018 Dec 3.

State Key Laboratory of Drug Research , Shanghai Institute of Materia Medica, Chinese Academy of Sciences , Shanghai 201203 , China.

IL-17 drives an amplification mechanism in inflammatory diseases such as psoriasis, psoriatic arthritis, and ankylosing spondylitis. The production of IL-17 depends on the activity of RORC2 in immune cells, which suggests that RORC2 inverse agonists are capable of anti-inflammatory therapy by reducing IL-17 levels. However, oral delivery of inverse agonists remains a challenge since the binding pocket of RORC2 prefers to accommodate lipophilic ligands, which tend to have poor metabolic stability. Read More
