Expression of transporter associated with antigen processing (TAP) is often lost in metastatic carcinomas, resulting in defective antigen processing and presentation and escape of the cancer cells from immune surveillance. In this study, the nature of TAP deficiencies in tumors was investigated. By chromatin immunoprecipitation assay, we showed that the recruitment of RNA polymerase II to the T...

T-cell-activating protein (TAP) is an allelic 12-kDa membrane protein that participates in T-cell activation. Soluble anti-TAP monoclonal antibodies can trigger antigen-specific, major histocompatibility complex-restricted T-cell hybridomas to produce interleukin 2 and are mitogenic for normal T cells and thymocytes. TAP is expressed on 10% of thymocytes, which are mainly cortisone-resistant an...

Background. There are a few papers that compared the lateral transversus abdominis plane (TAP) block with the posterior TAP block. Our study aimed to compare retrospectively the quality of analgesia after laparoscopic gynecologic surgery using the lateral TAP block with general anesthesia versus the posterior TAP block with general anesthesia. Method. Sixty-seven adult female patients were incl...

TAP is responsible for the transit of peptides from the cytosol to the lumen of the endoplasmic reticulum. In an immunological context, this event is followed by the binding of peptides to MHC molecules before export to the cell surface and recognition by T cells. Because TAP transport precedes MHC binding, TAP preferences may make a significant contribution to epitope selection. To assess the ...

background: it is considered that if radon gas is inhaled and ingested, it is the primary health risks for lung and stomach cancers. this paper presents the measurement results of radon activity concentrations both residential tap water and dam water for kastamonu city centre-turkey. materials and methods: the radon activity concentrations of water samples collected from 60 tap waters at four l...

Studies have been carried out to determine the potential for the detection of different microbial species (Enterobacter aerogenes, Escherichia coli, Pseudomonas aeruginosa), alone and in the presence of low concentrations of different heavy metals (As, Cd, Pb and Zn) in bottled, reverse osmosis (RO) and tap water, using an electronic nose. Studies show that it is possible to discriminate contro...
