Abstract: There is disclosed an antigenic peptide that comprises at least 15 amino acids having the sequence Ala Glu Pro Lys X Ala Glu Pro Lys X Ala Glu Pro Lys X, wherein X is Pro or Ser. This peptide is useful in an ELISA assay to detect antibodies specific to T. cruzi infection and Chagas disease. This peptide is further useful in a vaccine composition for immunizing an individual to prevent Chagas disease upon exposure to T. cruzi.
Abstract: A method for detecting anti-Leishmania parasite antibodies to a 230 kDa antigen present in Leishmania chagasi and Leishmania donovani is disclosed which comprises obtaining a sample from an individual, contacting the sample with a recombinant K39 repeat unit antigen comprising the amino acid sequence as shown in SEQ ID NO:3, and detecting the presence of anti-Leishmania parasite antibodies in the sample which bind to the recombinant K39 repeat unit antigen.
Abstract: Isolated viral proteins, and pharmaceutical compositions made therefrom, are disclosed which are capable of binding to Tumor Necrosis Factor, thereby functioning as Tumor Necrosis Factor antagonists. Also disclosed are processes for preparing isolated viral protein cytokine antagonists.

Abstract: Ligand reagents are disclosed which consist essentially of recombinant hyperglycosylated cytokines, expressed in yeast, which are purified and conjugated to various functional moieties, for example, biotin groups, via oligosaccharide residues. Methods of using such ligand reagents are also disclosed.
Abstract: There is disclosed an immunotherapy method for treating an individual with cancer or a viral infection comprising obtaining lymphoid cells previously exposed to a specific antigen, culturing the lymphoid cells ex vivo in a culture medium containing an effective amount of an IL-7 polypeptide or a functional derivative thereof to induce CTL activity in the lymphoid cells and administering the lymphoid cells having CTL activity for cells displaying the specific antigen to an individual.
