The current invention describes chimeric vaccine antigens against the virus that causes the Classic Swine Fever (CSFV). Such vaccine antigens are based on viral subunits coupled to proteins able to stimulate cellular and humoral immune system. Chimeric antigens can be produced in expression systems that guarantee a correct tertiary structure folding of the chimeric molecules, which constitute the essence of the current invention. The vaccine formulations containing such chimeric antigens induce an early and potent immune response on vaccinated pigs and confer full protection against CSFV. Moreover, the resultant vaccine formulations prevent the viral transmission from sows to their offspring. The chimeric antigens, as well as the resultant vaccine formulations, can be applied in animal health as vaccines for preventive use in swine.

This invention is related to the Molecular Pharmacology field and especially to the development of peptides useful for treating epithelial tumors and mainly those associated to oncogenic types of HPVs. The main objective of this invention is to identify peptides whose structure permits to block the Casein Kinase II (CKII) phosphorylation domain by direct interaction with such a site. In the present invention it is shown eleven cyclic peptides with different aminoacid sequences which inhibit the CKII phosphorylation in vitro, exhibit cytotoxicity on HPV-16 transformed cells (CaSki) and also increase the sensitivity of these cells to the cytostatic effect of interferon (IFN). Furthermore, the invention relates to the use of these peptides conjugated or fused to other peptides and chemical compounds which penetrates into cells as well as with the use of both peptide and chemical mimetic molecules.

The invention relates to HIV chimeric gene formed by the union of fragments of different genes of said virus, wherein said fragments contains epitopes for cytotoxic T cells (CTL) or HIV-1 auxiliary T cells, which are presented by a wide range of antigens of type Major Histocompatibility Complex (HLA-I). Recombinant poxviruses are obtained from said genes, which are useful for prophylactic and therapeutic vaccination against HIV/AIDS infections, are capable of generating a protective immune cell response in vaccinated laboratory animals and are recognized by the CTL lymphocytes of HIV/AIDS patients.
摘要:
A recombinant chimeric antagonist formed by a 60 amino acid fragment of the N-terminal region of human interleukin 2 (IL-2) fused to the N-terminal of the extracellular region of the alpha subunit of the gamma IFN (IFN γ) receptor. In vitro this protein has a T cell growth stimulating activity, it inhibits the growth stimulating activity of IL-2 in T cells, it inhibits the induction of HLA-DR by IFN γ and it inhibits the antiproliferative activity of γ IFN. This invention can be applied in the field of medicine for the treatment of several pathologies such as autoimmune diseases, graft rejections, chronic inflammations, sepsis, ischemia and reperfusion syndrome and atherosclerosis.
摘要:
A non-instrumental assay for the diagnosis of celiac disease based on the general immunochromatographic assay principles. The assay is rapid and simple and allows the reliable detection of anti transglutaminase antibodies, of both IgA and IgG isotype, in samples of human serum, plasma or blood, using as tracer the antigen transglutaminase conjugated to a colored substance, like colloidal gold or colored latex particles. The conjugated antigen is deposited onto an inert fibrous support, from where it can be released by a liquid sample. The antibodies in the sample react with the conjugated antigen developing an immunocomplex that migrates through a carrier membrane, like nitrocellulose or nylon with a pore size that allows a laminar flow of the reagents, until it reacts with the same antigen transglutaminase immobilized onto a reactive zone of the membrane. As a consequence of this reaction the immunocomplex will be trapped in the reaction site and a colored signal will be seen. Therefore a visually detectable signal in the reactive zone of the membrane indicates a positive result for the detection of anti transglutaminase antibodies in the sample.
摘要:
The present invention is for a pharmaceutical composition comprising an effective amount of an lipopolysaccharide (LPS) binding and -neutralizing peptide. The LPS binding and neutralizing peptides of the present invention are analogues of peptides from a lipopolysaccharide binding protein region whose primary sequence have been substituted at particular amino acid sites to obtain an effective binding to and neutralization of LPS.
摘要:
An immunogenic peptide for use in the prevention of parvovirus infections having a contiguous sequence of 6 to 25 amino acids. The peptide is produced from autonomous parvoviruses so as to be capable of inducing neutralizing antibodies against such viruses. These peptides correspond to antigenic sites located in the first 25 amino acids of the amino terminal end of the VP2 proteins of parvoviruses. When these peptides are coupled to carrier proteins or to other immunogenic complexes, they can be used in the formulation of vaccines appropriate to protect dogs, cats, pigs and minks against the infections caused by the parvoviruses.
摘要:
Human serum albumin is made by culturing a bacterium (e.g. E. coli) capable of providing for the stable maintenance of a plasmid containing an inducible promoter (e.g. P.sub.trp), a ribosome binding site (e.g. that of the CII gene of bacteriophage lambda not containing the t.sub.R1 sequence), and the human serum albumin gene possessing an ATG initiation codon at the 5' end.
