Copper ions are essential at a proper level yet toxic when present in excess. To maintain a proper intracellular level, cells must be able to sense the changes in copper ion concentrations. The yeast transcription factor Mac1p plays a critical role in the transcriptional regulation of CTR1 and CTR3, both encoding high affinity copper ion transporters. Here(More)
Epitope vaccines have shown promise for inducing cellular immune responses in animal models of infectious disease. In cases where cellular immunity was augmented, peptide vaccines composed of covalently linked minimal cytotoxic T-lymphocyte (CTL) and T-helper (T(H)) epitopes generally showed the most efficacy. To address a clinical vaccine strategy for(More)
BACKGROUND Human cytomegalovirus (CMV) is a ubiquitous herpesvirus that is an important complication of bone marrow and allogeneic stem-cell transplant (HSCT). CD8 T-lymphocytes have an important role in immunity against CMV, but correlation between antigen-specific subpopulations of these cells and protection are still unclear. METHODS Flow analysis with(More)
An inhibitor production typing (P-typing) scheme originally devised for hemolytic streptococci of Lancefield groups A-G has been successfully applied to 35 mutans streptococcus isolates recovered from plaque cultures of 60 Dunedin schoolchildren. Thirteen different P-type designations were identified. Although 11 (31%) of the isolates failed to produce(More)
A new method of treating dynamic dialysis data to obtain binding parameters for drug-macromolecule interactions is presented. This method allows the determination of binding parameters directly from dialysis data according to a theoretical model. It is not necessary to determine the dialysis rate constant accurately in a separate experiment, and bias is not(More)
