The aim of this study was to initiate a survey of human autoantibody responses to a panel of select colorectal tumor-associated antigens identified by previous serological analysis of a cDNA expression library and to subsequently identify multiple serological biomarkers for the detection of colorectal cancer. For screening of autoantibodies against colorectal tumor-associated antigens, sera fro...

PURPOSE We previously reported a randomized phase II clinical trial combining a poxvirus-based vaccine encoding prostate-specific antigen (PSA) with radiotherapy in patients with localized prostate cancer. Here, we investigate whether vaccination against PSA induced immune responses to additional tumor-associated antigens and how this influenced clinical outcome. EXPERIMENTAL DESIGN Pretreatm...

Antigens have been detected in 35 to 40% of sera from patients with leukemia that cross-react with the Mr 30,000 core proteins (p30) of baboon endogenous virus (BaEV) and/or of simian sarcoma-simian sarcoma-associated virus (SiSV) in a solid-phase enzyme immunoassay using anti-SiSV p30 and anti-BaEV p30 antisera. These antigens could not be found in sera from nonleukemic persons. Fetal calf ser...

The association of HLA and disease varies in different populations. We have . studied the association of HLA class I in Iranian psoriatic patients, in order to compare this association with other reports. Fifty-one Iranian patients with psoriasis were HLA typed. The frequency of HLA antigens in patients and patient subgroups, based on clinical patterns, age of onset, family history and prov...

The use of tumour-associated antigens for cancer immunotherapy studies is exacerbated by tolerance to these self-antigens. Tolerance may be broken by using ex vivo monocyte-derived dendritic cells (DCs) pulsed with self-antigens. Targeting tumour-associated antigens directly to DCs in vivo is an alternative and simpler strategy. The identification of cell surface receptors on DCs, and targeting...

introduction: intravenous drug users as a serious health problem in communities have economical and social effects as well as health and hygienic complications. viral infections may be transmitted through drug injection by shared syringes among users. the aim of this study has been to determine the relative frequency of hbv, hcv and hiv infection’s markers as epidemiological data in ahvaz. mate...

conclusions in hbeag positive chb patients, low serum hbsag level is a useful predictor of compensated cirrhosis. objectives the aim of our study was to evaluate serum hbsag level as a biomarker for compensated cirrhosis in hepatitis b e antigen (hbeag) positive chb patients. patients and methods two-hundred and one hbeag-positive chinese chb patients with or without cirrhosis were enrolled in ...

Granulomatous response in association with breast cancer and within the cancer draining lymph nodes is an extremely rare phenomenon. Granulomatous inflammation is an immune response commonly seen against infectious agents and certain non-neoplastic conditions. The etiopathogenesis of granulomas associated with malignancies is not clear but it may be because of an immunologic reaction to tumour ...

Background: Vaccines based on virus-like particles are effective against Human Papilloma Virus (HPV) infection; however, they have not shown a therapeutic effect against HPV-associated diseases. New immunotherapy strategies based on immune responses against tumor antigens can positively affect the clearance of HPV-associated lesions. Objective: To generate two therapeutic fusion DNA vaccines (o...
