PURPOSE Radiofrequency ablation (RFA) is a minimally invasive energy delivery technique increasingly used for focal therapy to eradicate localized disease. RFA-induced tumor-cell necrosis generates an immunogenic source of tumor antigens known to induce antitumor immune responses. However, RFA-induced antitumor immunity is insufficient to control metastatic progression. We sought to characteriz...

BACKGROUND Detection of immunogenic proteins remains an important task for life sciences as it nourishes the understanding of pathogenicity, illuminates new potential vaccine candidates and broadens the spectrum of biomarkers applicable in diagnostic tools. Traditionally, immunoscreenings of expression libraries via polyclonal sera on nitrocellulose membranes or screenings of whole proteome lys...

Cancer is one of the leading causes of morbidity and mortality worldwide; therefore there is a need to discover new therapeutic modules with improved efficacy and safety. Immune-(cell) therapy is a promising therapeutic strategy for the treatment of intractable cancers. The effectiveness of certain chemotherapeutics in inducing immunogenic tumor cell death thus promoting cancer eradication has ...

The selection of nontumorigenic (turn'), highly immunogenic variants from four different tumorigenic but poorly immuno genic murine tumors by mutagen treatment and cloning is described. Several factors were found to determine the suc cessful nature of this selection procedure including: the nature of the tumor used; the nature of the mutagen; the number of mutagen treatments; and the time at wh...

Transfection of the undifferentiated murine colon carcinoma line CT-26 with the gene coding for the hemagglutination antigen (HA) of influenza virus resulted in the generation of highly immunogenic tumor cells. CT-26 cells transfected with HA not only failed to grow in syngeneic mice but also protected normal animals against a challenge with otherwise lethal doses of parental nontransfected cel...

background: lipopolysaccharides (lpss) and several antigenic proteins of brucella have been considered for preparation of diagnostic reagents and subunit vaccines. the objective of this study was to identify and compare immunogens of b. abortus s19 which induce humoral immune responses in human, goat and rabbit.   material and methods: the bacterial whole cell extract was prepared in extraction...

A primary immunogenic uveitis was produced in rabbits by the intravitreal injection of bovine plasma albumin or ovalbumin. A secondary or recurrent uveitis was induced by intravenous injection of the specific soluble antigen several months after the cessation of primary inflammation. Aqueous antigen-antibody complexes were studied at times of maximal clinical response in both primary and recurr...
