One influential account asserts that the anterior temporal lobe (ATL) is a domain-general hub for semantic memory. Other evidence indicates it is part of a domain-specific social cognition system. Arbitrating these accounts using functional magnetic resonance imaging has previously been difficult because of magnetic susceptibility artifacts in the region.(More)
A number of adenocarcinomas abundantly express and secrete underglycosylated MUC1 mucin. Underglycosylation exposes tandem repeat peptide sequences on cancer-associated MUC1 mucin that are normally cryptic. High levels of MUC1 mucin are correlated with a poor prognosis and immunosuppression in adenocarcinoma patients. In this report we show that(More)
BACKGROUND Group A streptococcus (GAS) causes illness ranging from uncomplicated pharyngitis to life-threatening necrotizing fasciitis, toxic shock, and rheumatic fever. Attempts to develop an M protein-based vaccine have been hindered by the fact that some M proteins elicit both protective antibodies and antibodies that cross-react with human tissues. New(More)
Sixteen research groups participated in the ISOBM TD-4 Workshop in which the reactivity and specificity of 56 monoclonal antibodies against the MUC1 mucin was investigated using a diverse panel of target antigens and MUC1 mucin-related synthetic peptides and glycopeptides. The majority of antibodies (34/56) defined epitopes located within the 20-amino acid(More)
A multivalent vaccine containing amino-terminal M protein fragments from 26 different serotypes of group A streptococci was constructed by recombinant techniques. The vaccine consisted of four different recombinant proteins that were formulated with alum to contain 400 microg of protein per dose. Rabbits were immunized via the intramuscular route at 0, 4,(More)
CONTEXT Group A streptococcal infections and their sequelae represent a global health problem. Recent advances have allowed previous obstacles associated with group A streptococcal vaccine development to be overcome. OBJECTIVE To preliminarily evaluate the safety and immunogenicity of ascending doses of a recombinant fusion peptide group A streptococcal(More)
Sixteen metastatic breast cancer patients were immunized with a low dose (5 micrograms) of a 16 amino acid MUC1 peptide (GVTSAPDTRPAPGSTA) conjugated to KLH (BP16-KLH) plus DETOX adjuvant and evaluated for antibody titers against MUC1 peptide and KLH and for cytotoxic lymphocyte (CTL) activity using class 1 HLA-matched MUC1-positive tumor targets. All(More)
Patients with metastatic breast, colorectal or ovarian cancers received active specific immunotherapy (ASI) with Theratope sialyl-Tn-KLH (keyhole limpet hemocyanin) cancer vaccine emulsified in Detox adjuvant. The median log2 anti-STn IgG titer generated by ASI, estimated by enzyme-linked immunosorbent assay with solid-phase ovine submaxillary mucin, was(More)
Antigen-specific MHC class II- and class I-restricted helper and cytotoxic T cell responses are important anti-cancer immune responses. MUC1 mucin is a potentially important target for immunotherapy because of its high expression on most human adenocarcinomas. MUC1 peptide-specific type 1 T cell responses were generated in vitro using human peripheral blood(More)
We generated a synthetic epitope, NANA alpha(2-6) GalNAc alpha-O-Crotyl (STn-crotyl), designed to "mimic" the natural O-linked epitope expressed on human carcinoma cells, NANA alpha(2-6)GalNAc alpha-O-Serine (STn-serine). STn-crotyl was conjugated to the carrier protein KLH through the crotyl linker arm, and a "vaccine" containing STn-KLH plus DETOX(More)
