OP0205 Gut Dysbiosis in Patients with HLA-B27+ Ankylosing Spondylitis is Associated with Ileitis, Down-Regulation of Tight Junction Proteins, Increas…

2015

Background Intestinal dysbiosis has been recently demonstrated in the inflamed ileum of AS patients. Objectives To study the ileal localization of bacteria in AS patients and their relationship with local and systemic immune responses. Methods Consecutive gut biopsies obtained from 30 HLA-B27 + AS patients and 20 normal subjects were histologically classified in normal histology, acute inflammation and chronic inflammation. Giemsa and Silver stains were used to visualize bacteria and characterize their morphology. Intestinal bacteria were scored on the basis of the numbers of bacteria and their aggregation in clusters. The ileal expression and tissue distribution of claudin-2 and 4, Zonulin…

OP0081 Aberrant Expression of IL-22RA1 on Hematopoietic Cells as Immunologically Signature of Primary Sjogren’s Syndrome and Sjogren-Associated Non-H…

2013

Background Interleukin (IL)-22 is a potent mediator of cellular inflammatory responses that has been recently reported to play a role in the pathogenesis of primary Sjogren’s Syndrome (p-SS) (1, 2) and of T and B lymphomas. IL-22 biological activity is initiated by binding to a cell-surface complex composed of two subunits, IL-22R1 and IL-10R2 receptor chains, and further regulated by interactions with a soluble binding protein, IL-22BP. Unlike the IL-10R2, which is constitutively expressed in many human tissues, IL-22R1 is not detectable in immune cells. Objectives Aim of this study was to better characterize the role of IL-22 axis in the pathogenesis of p-SS and p-SS-associated lymphomas.…

Diabetes and cancer: A critical appraisal of the pathogenetic and therapeutic links.

2014

Diabetes and cancer represent two common, multifactorial, chronic and potentially fatal diseases, not infrequently co-diagnosed in the same patient. Epidemiological data demonstrate significant increases of the cancer incidence in patients with obesity and diabetes, which is more evident for certain site-specific cancers. Although there is increasing evidence that strongly indicates an augmented risk of cancer in diabetic patients, several confounding factors complicate the ability to precisely assess the risk. Mainly in insulin-resistant states (such as in type 2 diabetes mellitus and in metabolic syndrome), direct associations between obesity-related hyperinsulinemia and increasing circul…

Spectrum of novel mutations found in Waardenburg syndrome types 1 and 2: implications for molecular genetic diagnostics

2013

Objectives Till date, mutations in the genes PAX3 and MITF have been described in Waardenburg syndrome (WS), which is clinically characterised by congenital hearing loss and pigmentation anomalies. Our study intended to determine the frequency of mutations and deletions in these genes, to assess the clinical phenotype in detail and to identify rational priorities for molecular genetic diagnostics procedures. Design Prospective analysis. Patients 19 Caucasian patients with typical features of WS underwent stepwise investigation of PAX3 and MITF . When point mutations and small insertions/deletions were excluded by direct sequencing, copy number analysis by multiplex ligation-dependent probe …

Identification of Metastasis Associated Antigen 1 (MTA1) by Serological Screening of Prostate Cancer cDNA Libraries

2008

Over the past 10 years the serological analysis of recombinant cDNA expression libraries (SEREX) has proved to be an effective method for the identification of tumour antigens. In the present study, two prostate cancer libraries were constructed and screened using autologous sera. Fifty five genes were isolated, including 46 known genes and 9 previously uncharacterised genes. Among the known genes, a metastasis-associated gene, MTA1, previously identified by differential cDNA hybridisation, was preferentially expressed in a panel of malignant tissues compared with normal tissues, as analysed by reverse transcriptase-polymerase chain reaction (RT-PCR). MTA1 transcripts were observed to be ov…
