摘要:
Provided are a method and a kit for accurately and rapidly detecting ten types of targeting pneumonia bacteria: Streptococcus pneumoniae, Haemophilus influenzae, Mycoplasma pneumoniae, Chlamydophila pneumoniae, Legionella pneumophila, Klebsiella pneumoniae, Pseudomonas aeruginosa, Moraxella catarrhalis, methicillin-resistant Staphylococcus aureus (MRSA), and Staphylococcus aureus. A set of primer pairs directed to their respective target regions contained in the DnaJ gene, etc., of the ten types of pneumonia causative bacteria is designed for the ten bacterial strains and used to amplify gene products. A set of bacterial strain-specific probe pairs is further designed for the ten bacterial strains such that the probe pairs hybridize with the amplification products via sequences in the respective target regions differing from the sequences hybridized by the set of primer pairs. A first probe-bound labeled high molecular carrier in which plural types of first probes for the pneumonia bacteria are bound to a labeled high molecular carrier and a solid-phase second probe-carrying developing support are used as the set of probe pairs to perform nucleic acid chromatography.
摘要:
Peptide constructs comprised of multideterminant T helper peptides from the envelope glycoprotein of HIV previously identified to induce proliferative responses in four different haplotypes of mice and IL-2 responses in 52-73% of HIV positive, flu positive patients (cluster peptides), were co-linearly synthesized with the peptide 18 of the V3 loop of HIV-1 gp 160, corresponding to the principal neutralizing determinant of HIV-IIIB and also shown to contain a dominant CTL epitope. Cognate help for peptide 18 antibody was elicited following a single immunization in all strains of mice which had previously responded to a T cell epitope encompassed by the peptides. In two strains of mice, the level of neutralizing antibody achieved was comparable to levels adequate for protection from homologous viral challenge in chimpanzees. After a single boost, much higher antibody titers for 90% neutralization in the range of 1:1000 to 1:16,000 were achieved. Spleen cells from mice of three distinct MHC haplotypes sharing the Dd class I MHC molecule but with different class II molecules, immunized with the compound peptides, exhibited enhanced gp160-specific CTL activity.

摘要:
A method of treating or reducing at least one inflammatory condition or the susceptibility to at least one inflammatory condition is provided involving administering at least one CD69 antagonist to a subject, wherein the subject has been diagnosed with at least one inflammatory condition, or a susceptibility to the same. CD69 antagonists can include one or more of an anti-CD69 antibody, an anti-CD69 aptamer, a CD69 mRNA antagonist, and a small molecule pharmaceutical.

摘要:
The cytotoxic T cell response to the protein encoded by the NS5 region of hepatitis C virus was determined using 28 peptides from NS5 which were selected by an amphipathicity algorithm as candidates for T cell epitopes. In BALB/c mice, a single relatively conserved epitope represented by a 16-residue synthetic peptide was presented by D.sup.d class I major histocompatibility complex (MHC) molecules to conventional CD4.sup.- CD8.sup.+ CTL. An exemplary peptide, which represents amino acid residues 2422-2437 of the polyprotein of the Chiron HCV1 isolate, had the amino acid sequence MSYSWTGALVTPCAAE [SEQ ID NO: 1]. A CTL line specific for this peptide recognized the two known natural variants of this NS5 sequence, each with conservative substitutions. Thus, CTL can recognize the product of the HCV NS5 gene, the probable RNA polymerase, in association with class I MHC molecules on model target cells and may recognize the same epitope on hepatocytes or any other cells infected with the virus.

Peptides having high activity in the eliciting of a cytotoxic T lymphocyte response to the HIV-1 envelope glycoprotein gpl60 are described. The activation of 12-15 residue peptides by proteolytic degradation to shorter peptides is shown as are general techniques for characterizing such activation processes.
