摘要:
A method of genotyping blood cell antigens comprising subjecting DNA from an individual of a mammalian species to a multiplex Polymerase Chain Reaction (PCR) to amplify and detectably label a region of the locus of at least two different blood cell antigens which contains the site of nucleotide polymorphism of said blood cell antigen and using the thus amplified and labeled DNA fragments to determine the genotype for each of said blood cell antigens. The multiplex PCR comprises the use of at least one pair of blood cell antigen-specific chimeric primers for each blood cell antigen to be genotyped and at least one detectably labeled universal primer, preferably a pair of detectably labeled universal primers. The universal primer(s) have a unique sequence not occurring in the DNA of said mammalian species. Each chimeric primer pair comprises a left chimeric primer and a right chimeric primer, each of them comprising a blood cell antigen-specific part at the 3' end and a universal part at the 5' end. The base sequence of the universal part of the chimeric primers corresponds to the base sequence of said at least one universal primer. The blood cell antigen-specific parts of the chimeric primer pair enclose a region of the locus of the blood cell antigen which contains the site of nucleotide polymorphism of said blood cell antigen. A kit for genotyping blood cell antigens by this method. A set of blood cell antigen-specific chimeric primer pairs and a set of blood cell antigen allele-specific oligonucleotide probes.

The invention relates to diagnostic methods to predict whether a subject is predisposed for acquiring a disease or to predict the therapy responsiveness of an individual patient. Provided is a method for determining whether a subject is predisposed for developing an autoimmune disease, comprising determining in a sample isolated from said subject the amount of intact genes, or gene products thereof, of the FcϜRII/FcϜRIII gene cluster, said gene cluster comprising the FCGR2C, FCGR3A, FCGR2A and FCGR3B genes encoding an activating FcϜR, and FCGR2B encoding an inhibitory FcϜ R; and correlating said amount to the amount observed in a healthy population. Also provided is a method to predict the responsiveness of a subject to therapy with intravenous immunoglobulin (IVIg) therapy or a monospecific biological, such as a humanized or human monoclonal antibody or a chimeric molecule, comprising the C-terminal Fc-tail of IgG.

This invention relates to the field of prion diseases. A method is provided to reduce false positive outcomes in a test by monitoring the activity of a proteolytic enzyme in a test sample comprising providing the test sample with a substrate and contacting the enzyme with said substrate to allow conversion of the substrate by the enzyme into a detectable product and detecting said product. Use of a method according to the invention can improve the reliability of prion tests.
摘要:
Novel inhibitors of the contact system were developed by a) the discovery that the sequence encompassing the amino acid residues 39 to 47 of the heavy chain region of human FXII contributes to the binding of FXII to activators such as negatively charged surfaces; and b) the demonstration that peptides mimicking this identified sequence inhibit the binding of FXII to activators and prevent contact system activation in human plasma. These novel contact system inhibitors may be applied to prevent activation of the contact system of blood by artificial surfaces, or used as anti-inflammatory drug for the prophylactic or therapeutic treatment of human or animal diseases.
摘要:
CD97 is an activation-induced antigen on leucocytes with a seven-span transmembrane (7-TM) region homologous to the secretin receptor superfamily. However, in contrast to this group of peptide hormone receptors, CD97 has an extended extracellular region with three EGF domains at the N-terminus, two of them with a calcium binding site. Lymphocytes and erythrocytes specifically adhere to CD97-transfected COS cells which is blocked by a monoclonal antibody (mAb) directed to the N-terminal short consensus repeat (SCR) of decay accelerating factor (DAF, CD55), a regulatory protein of the complement cascade. Erythrocytes that lack CD55, obtained from patients with paroxysmal nocturnal hemoglobinuria (PNH) or the CD55- phenotype Inab, failed to adhere to CD97 transfectants. The invention provides methods and means to interfere in the binding of CD97 and CD55. This will be especially useful in xenotransplant medicine where CD55 is used to down regulate the complement activation pathway.
摘要:
Dextran sulphate is used to potentiate C1-esterase inhibitor selectively with respect to inhibition of complement and coagulation, but not with respect to inhibition of the contact and fibrinolytic systems. The C1-esterase inhibitor to be potentiated by the dextran sulphate may be endogenous C1-esterase inhibitor, or exogenous C1-esterase inhibitor which is to be administered together with or separate from the dextran sulphate. Use of the dextran sulphate, alone or together with C1-esterase inhibitor, in prophylactic or therapeutic treatment of inflammatory conditions, such as sepsis and myocardial infarction.
