Abstract
Despite large-scale efforts devoted to the conduct of clinical trials in systemic lupus erythematosus (SLE), no new therapy has been approved for treatment of this disease in more than 50 years. Increased understanding of the immunologic mechanisms underlying SLE has led to the devel...

Abstract
Cardiovascular disease, the most common cause of death with a functioning graft among kidney transplant recipients, can be exacerbated by immunosuppressive drugs, particularly the calcineurin inhibitors. Belatacept, a selective co-stimulation blocker, may provide a better cardiovascu...

Abstract
We describe the design, production and characterization of a novel immunocytokine, in which murine interferon-alpha2 was sequentially fused with the tumor-targeting antibody fragment scFv(F8), specific to the alternatively-spliced EDA domain of fibronectin. The resulting fusion protein (F8-IFNa) cou...

Abstract
We have described the generation of quorum quenching monoclonal antibodies (mAbs) against acyl homoserine lactones (AHL) used by Pseudomonas aeruginosa as well as Staphylococcal autoinducing peptides (AIP). These mAbs suppressed QS signaling in bacteria and neutralized AHL-mediated cytotoxic effects...

Abstract
B7 ligands deliver both costimulatory and coinhibitory signals to the CD28 family of receptors on T lymphocytes, the balance between which determines the ultimate immune response. Although B7-H4, a recently discovered member of the B7 family, is known to negatively regulate T cell im...

Abstract
Monoclonal antibodies (mAbs) and derivatives are currently the fastest growing class of therapeutic molecules. More than 30 G-type immunoglobulins (IgG) and related agents have been approved over the past 25 years mainly for cancers and inflammatory diseases. In oncology, mAbs are often combined wit...

The mean labelling ratio of (211)At-labelled antibodies was 1:1,090 +/- 364 (range: 1:738-1:1,722) in comparison to 2-3:1 for GO. Tumour cell binding of (211)At-anti-CD33 was high in the presence of abundant CD33 expression and could be specifically blocked by unlabelled anti-CD33. (211)At-anti-CD33...
