Proinflammatory Cytokine Profiling of Tears from Dry Eye Patients by Means of Antibody Microarrays
2011
In the pathogenesis of keratoconjunctivitis sicca, immune processes are thought to play an important role. However, the exact details of the pathomechanisms are still unknown. In this study, the expression patterns of proinflammatory cytokines in the tears of patients with different subtypes of dry eye were analyzed.One hundred forty-three subjects subdivided into healthy controls (CTRL, n = 38), patients with aqueous-deficient dry eye (DRYaq, n = 35), patients with changes of the lipid layer (DRYlip, n = 36), and patients with a combination of both (DRYaplip, n = 34) were examined. Expression patterns of proteins (e.g., IL-1β, IL-6, ITNF-α, and IFN-γ) were examined using an advanced antibo…
Proteomics Differentiate Between Thyroid-Associated Orbitopathy and Dry Eye Syndrome.
2015
PURPOSE: In patients with thyroid-associated orbitopathy (TAO), the dry eye syndrome occurs frequently, and symptoms and signs of both disorders overlap making early and accurate differential diagnosis difficult. A differentiation via specific markers is warranted. METHODS: Tear fluid samples of 120 subjects with TAO, TAO + dry eye, dry eye, and controls were collected. The samples were measured using matrix-assisted laser desorption ionization mass spectrometry. The identified proteins were tested with antibody microarrays. RESULTS: Proteomics identified deregulated proteins in TAO and dry eye. Compared with dry eye, proline-rich protein 1 (PROL1, P = 0.002); uridine diphosphate (UDP)-gluc…
Antibody microarray analysis of the serum proteome in primary breast cancer patients
2011
Noninvasive biomarkers are urgently needed for detecting breast cancer as early as possible since the risk of recurrence, morbidity, and mortality is closely related to disease stage at the time of primary surgery. There are currently no such biomarkers in clinical use as a diagnostic tool. Proteomic analysis of protein expression patterns in body fluids has potential for use in identifying biomarkers of breast cancer. The aim of this study was to compare protein expression levels in the sera of primary breast cancer patients and healthy controls. An antibody microarray tool with 23 antibodies immobilized on nitrocellulose slides was used to determine the levels of acute phase proteins, int…
Microarray analysis of antibodies induced with synthetic antitumor vaccines : specificity against diverse mucin core structures
2017
Glycoprotein research is pivotal for vaccine development and biomarker discovery. Many successful methodologies for reliably increasing the antigenicity toward tumor-associated glycopeptide structures have been reported. Deeper insights into the quality and specificity of the raised polyclonal, humoral reactions are often not addressed, despite the fact that an immunological memory, which produces antibodies with cross-reactivity to epitopes exposed on healthy cells, may cause autoimmune diseases. In the current work, three MUC1 antitumor vaccine candidates conjugated with different immune stimulants are evaluated immunologically. For assessment of the influence of the immune stimulant on a…
