Endometrial cancer is the most frequent gynecological malignancy in the developed world. Currently, endometrial histology is the gold standard for diagnosis, as there are no valid noninvasive diagnostic methods available. Biomarkers for endometrial cancer would be invaluable for screening of high-risk women, detection of primary and recurrent disease, and preoperative stratification of patients as high-risk and low-risk categories, enabling personalized therapeutic approaches. Areas covered: This report reviews publications of blood biomarkers evaluated in patients with endometrial cancer and/or control patients, over the last five years...

Several pretransplant factors, including CRP (C-reactive protein) levels, reflect the risk of complications after allogeneic stem cell transplantation. IL-6 induces CRP increase, and we therefore investigated the effects of pretransplant IL-6, soluble IL-6 receptors, IL-6 family cytokines and CRP serum levels on outcome for 100 consecutive allotransplant recipients. All patients had related donors, none had active infections and 99 patients were in complete remission before conditioning. The incidence of acute graft versus host disease (aGVHD) requiring treatment was 40%, survival at Day +100 82%, and overall survival 48%...

Scratching is an important factor exacerbating skin lesions through the so-called itch-scratch cycle in atopic dermatitis (AD). In mice, interleukin (IL)-31 and its receptor IL-31 receptor A (IL-31RA) are known to play a critical role in pruritus and the pathogenesis of AD; however, study of their precise roles in primates is hindered by the low sequence homologies between primates and mice and the lack of direct evidence of itch sensation by IL-31 in primates. We showed that administration of cynomolgus IL-31 induces transient scratching behavior in cynomolgus monkeys, and by that were able to establish a monkey model of scratching...

IL-33 modulates both innate and adaptive immune responses at tissue sites including lung and may play critical roles in inflammatory lung disease. Although IL-33 expression can be altered upon NF-Kappa B activation, here we examine regulation by Oncostatin M, a gp130 cytokine family member, in mouse lung tissue. Responses were assessed in BALB/c mouse lung at day 7 of transient overexpression using endotracheally administered adenovirus encoding OSM (AdOSM) or empty vector (AdDel70). Whole lung extracts showed induction of IL-33 mRNA (>20-fold) and protein (10-fold increase in immunoblots) by AdOSM relative to AdDel70...

BACKGROUND: Atopic dermatitis (AD) affects 15% to 25% of children and 4% to 7% of adults. Paradigm-shifting discoveries about AD have been based on adult biomarkers, reflecting decades of disease activity, although 85% of cases begin by 5 years. Blood phenotyping shows only TH2 skewing in patients with early-onset pediatric AD, but alterations in early pediatric skin lesions are unknown, limiting advancement of targeted therapies. OBJECTIVE: We sought to characterize the early pediatric AD skin phenotype and its differences from pediatric control subjects and adults with AD...

Interleukin-31 (IL-31) is a type 2 helper T-cell-derived cytokine that has recently been shown to cause severe inflammation and tissue remodeling in multiple chronic diseases of the skin and lungs. IL-31 is upregulated in allergic and inflammatory diseases, including atopic dermatitis, asthma, cutaneous T-cell lymphomas, and allergic rhinitis, as well as autoimmune diseases such as systemic erythematosus. Overexpression of IL-31 in T cells causes severe inflammation, with histological features similar to skin lesions of patients with atopic dermatitis...

BACKGROUND: The ichthyoses are rare genetic disorders associated with generalized scaling, erythema, and epidermal barrier impairment. Pathogenesis-based therapy is largely lacking, since the underlying molecular basis is poorly understood. OBJECTIVE: To characterize molecularly cutaneous inflammation and its correlation with clinical and barrier characteristics. METHODS: We analyzed biopsies from 21 genotyped ichthyosis patients (congenital ichthyosiform erythroderma (n=6), lamellar ichthyosis (n=7), epidermolytic ichthyosis, (n=5) and Netherton syndrome (n=3)) by immunohistochemistry and RT-PCR and compared them with healthy controls, and atopic dermatitis (AD) and psoriasis patients...

BACKGROUND: Overexpression or administration of interleukin 31 (IL-31) has been shown to induce a profound itch response in mice and dogs. The chronic pruritus observed in mouse IL-31 transgenic mice results in the development of skin lesions and alopecia through excoriation from excessive scratching, a condition similar to that observed in patients with atopic dermatitis (AD). OBJECTIVE: To test whether IL-31 induces pruritus in non-human primates and, if so, whether treatment with an anti-IL-31 neutralizing monoclonal antibody (mAb) can block the response...

T-helper (Th) 17 cells are a pro-inflammatory subset of CD4(+) effector T-cells critical in mucosal immunity. Imbalances in Th17 cell proportion have been implicated in the pathogenesis of several diseases; however, this has not been adequately explored in tuberculosis (TB) and human immunodeficiency virus (HIV) co-infection. Since Th17 cells are predominantly mucosally associated, we assessed Th17 proportion and associated microenvironment in pleural effusions from patients co-infected with TB/HIV. Our results show that TB(+)HIV(+) pleurisy results in significantly reduced frequency of CD4(+)IL-17(+)RORC(+)STAT3(+) Th17 cells compared to TB(-)HIV(-)ex vivo (p = 0...

The pathogenesis of chronic and acute pruritus is not yet completely understood. Interactions of neurons with resident and nonresident skin cells seem to play an important role in the regulation of pruritus. Neuronal cells which express specific receptors and are capable of releasing neuromediators play an active role in this interaction. Furthermore, released neuromediators can activate immune cells including mast cells and eosinophils, which are increased in the inflammatory infiltrate of many pruritic skin diseases...

Data on interleukin-31 (IL-31) involvement in the patho-genesis of mastocytosis, and its impact on pruritus development in the disease, are limited. The aim of this study was to analyse distinct IL-31 gene polymorphisms in 127 patients (age 0.5-76 years) with mastocytosis and their correlation with clinical presentation, pruritus and serum IL-31 levels. In patients with mastocytosis, the frequency of IL-31 IVS2+12AA genotype and IVS2+12A allele was higher than in control subjects and they were linked to an increased risk of development of mastocytosis...

BACKGROUND: Pruritus is a cardinal symptom of atopic dermatitis, and an increased cutaneous sensory network is thought to contribute to pruritus. Although the immune cell-IL-31-neuron axis has been implicated in severe pruritus during atopic skin inflammation, IL-31's neuropoietic potential remains elusive. OBJECTIVE: We sought to analyze the IL-31-related transcriptome in sensory neurons and to investigate whether IL-31 promotes sensory nerve fiber outgrowth. METHODS: In vitro primary sensory neuron culture systems were subjected to whole-transcriptome sequencing, ingenuity pathway analysis, immunofluorescence, and nerve elongation, as well as branching assays after IL-31 stimulation...
