Division of Biological Sciences, Research Institute of Women's Health and Cellular Heterogeneity Research Center, Sookmyung Women's University, Seoul 04310, Republic of Korea.

Myeloid-derived suppressor cells (MDSCs) that are able to suppress T cell function are a heterogeneous cell population frequently observed in cancer, infection, and autoimmune disease. Immune checkpoint molecules, such as programmed death 1 (PD-1) expressed on T cells and its ligand (PD-L1) expressed on tumor cells or antigen-presenting cells, have received extensive attention in the past decade due to the dramatic effects of their inhibitors in patients with various types of cancer. In the present study, we investigated the expression of PD-1 on MDSCs in bone marrow, spleen, and tumor tissue derived from breast tumor-bearing mice. Read More

Peptidylarginine deiminases 2 and 4 modulate innate and adaptive immune responses in TLR-7-dependent lupus.

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

Systemic Autoimmunity Branch, Intramural Research Program (IRP), National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS), and.

The peptidylarginine deiminases PAD2 and PAD4 are implicated in the pathogenesis of several autoimmune diseases. PAD4 may be pathogenic in systemic lupus erythematosus (SLE) through its role in neutrophil extracellular trap (NET) formation that promotes autoantigen externalization, immune dysregulation, and organ damage. The role of this enzyme in mouse models of autoimmunity remains unclear, as pan-PAD chemical inhibitors improve clinical phenotype, whereas PAD4-KO models have given conflicting results. Read More

Siglec-1 Macrophages and the Contribution of IFN to the Development of Autoimmune Congenital Heart Block.

J Immunol 2018 Dec 5. Epub 2018 Dec 5.

Division of Rheumatology, Department of Medicine, New York University School of Medicine, New York, NY 10016.

Given that diseases associated with anti-SSA/Ro autoantibodies, such as systemic lupus erythematosus and Sjögren syndrome, are linked with an upregulation of IFN and type I IFN-stimulated genes, including sialic acid-binding Ig-like lectin 1 (Siglec-1), a receptor on monocytes/macrophages, recent attention has focused on a potential role for IFN and IFN-stimulated genes in the pathogenesis of congenital heart block (CHB). Accordingly, three approaches were leveraged to address the association of IFN, IFN-stimulated genes, and the phenotype of macrophages in affected fetal cardiac tissue: 1) cultured healthy human macrophages transfected with hY3, an anti-SSA/Ro-associated ssRNA, 2) RNA isolated from freshly sorted human leukocytes/macrophages after Langendorff perfusion of three fetal hearts dying with CHB and three healthy gestational age-matched hearts, and 3) autopsy tissue from three additional human CHB hearts and one healthy heart. TLR ligation of macrophages with hY3 led to the upregulation of a panel of IFN transcripts, including SIGLEC1, a result corroborated using quantitative PCR. Read More

Multiple sclerosis is an inflammatory neurodegenerative disease of the central nervous system (CNS) and the most frequent cause of non-traumatic disability in adults in the Western world. Currently, several drugs have been approved for the treatment of multiple sclerosis. While the newer drugs are more effective, they have less favourable safety profiles. Read More

Advances in rheumatology practice in Brazil.

Rheumatol Int 2018 Dec 1. Epub 2018 Dec 1.

Laboratório de Investigação em Osteoartropatias, Department of Internal Medicine, Liga de Reumatologia e Doenças Autoimunes, Instituto de Biomedicina, Faculdade de Medicina, Federal University of Ceará, Rua Cel. Nunes de Melo, 1315, 1°. Andar, Rodolfo Teófilo, Fortaleza, CE, 60430-270, Brazil.

Despite resilient inequities, Brazil has seen progressive improvement in health care in the last 25 years. Infectious diseases rendered place to chronic non-communicable diseases as a major cause of death. Existence of traditional schools of medicine and training services in rheumatology helped form a reasonable number of specialists, though irregular distribution due to the economic issues favoring their clustering in major cities.

Comparing early and late treatments with rituximab in pemphigus vulgaris: which one is better?

Arch Dermatol Res 2018 Dec 1. Epub 2018 Dec 1.

Autoimmune Bullous Diseases Research Center, Razi Hospital, Tehran University of Medical Sciences, Vahdate-Eslami Square, Tehran, 11996, Iran.

During the last decade, successfully treatment of patients diagnosed with pemphigus vulgaris (PV) with rituximab (RTX) was reported by several authors. The present study has been designed to compare the clinical outcomes and RTX-related side effects between the two groups of early treated (≤ 6 months) and lately treated PV (> 6 months) patients with RTX. We did a retrospective study between Oct 2014 and Jun 2016 to compare the short-term efficacy and safety of RTX in PV diagnosed patients. Read More

Current understanding of allergic fungal rhinosinusitis.

World J Otorhinolaryngol Head Neck Surg 2018 Sep 9;4(3):179-185. Epub 2018 Nov 9.

McGovern Medical School at the University of Texas Health Science Center, Department of Otorhinolaryngology-Head & Neck Surgery, Houston, TX 77030, USA.

Studying the pathophysiology of allergic fungal rhinosinusitis (AFRS) has proved challenging. While this clinical entity is easily distinguishable based on the clinical criteria set forth by Bent and Kuhn twenty-five years ago, studies examining type 2 inflammatory profiles in AFRS can make it seem more alike other CRS subtypes than it is different. Still, evolving research seems to clearly delineate this subtype from others in CRS. Read More

Macular serpiginous choroiditis - case report.

Rom J Ophthalmol 2018 Jul-Sep;62(3):217-221

Anatomy Department, "Carol Davila" University of Medicine and Pharmacy, Bucharest, Romania.

Serpiginous choroiditis represents an inflammation, often asymmetric, situated at the level of the inner choroid, which is related to the retinal pigment epithelium and the choriocapillaris. It is known as a primarily idiopathic, but there are authors who consider it an autoimmune process. Many times, fundus autofluorescence is the investigation which is guiding the diagnosis, the management, also the follow-up together with the determination of the progressive visual prognosis.

The Utilization of Autoantibodies in Approaches to Precision Health.

Front Immunol 2018 16;9:2682. Epub 2018 Nov 16.

Inova Diagnostics Inc., San Diego, CA, United States.

Precision health (PH) applied to autoimmune disease will need paradigm shifts in the use and application of autoantibodies and other biomarkers. For example, autoantibodies combined with other multi-analyte "omic" profiles will form the basis of disease prediction allowing for earlier intervention linked to disease prevention strategies, as well as earlier, effective and personalized interventions for established disease. As medical intervention moves to disease prediction and a model of "intent to PREVENT," diagnostics will include an early symptom/risk-based, as opposed to a disease-based approach. Read More
