An assay for the diagnosis of multi-infarct dementia and dementia of the Alzheimer type in an individual is provided. It comprises the steps of obtaining a sample from said individual being a blood sample, a platelet-containing fragment thereof, or a fragment containing platelet associated antibodies (PAA) detached from the platelets, and then determining the level of a platelet associated antibody against a 75 kD platelet-protein in said sample. A level higher than that of a control sample indicates that said individual has a high likelihood of having multi-infarct dementia or dementia of the Alzheimer type.

摘要:
The present invention concerns a mammalian cell line which when co-cultured with lymphocytes during which allogenic stimulation is avoided activates lymphocytes fo form tumoricidal cells, a process for the production of tumoricidal T lymphocytes by co-culturing lymphocytes with this cell line, the tumoricidal T lymphocytes obtained by means of this process and the use of the cells according to the present invention for the production of a therapeutic agent which can be used in tumour therapy.
摘要:
The present invention concerns a method for determining the degranulation activity of basophilic granulocytes in a sample as well as a reagent kit that is suitable for this. Furthermore the invention also concerns a method for diagnosing allergic hypersensitivity and for monitoring the response to a hyposensitization therapy.
摘要:
The present invention relates generally to a molecular marker of the integrity of the extracellular matrix in an animal including a human subject. More particularly, the present invention provides a molecular marker of cartilage integrity. The identification of the molecular marker in circulatory or tissue fluid is indicative of disrepair of the extracellular matrix and in particular cartilage such as caused or facilitated by trauma or a degenerative disease or other condition, for example, arthritis or autoimmunity. The molecular marker is preferably in the form of a glycoprotein but the instant invention extends to genetic sequences encoding the polypeptide portion of the glycoprotein. Expression analysis of such genetic sequences provides predictive utility in detecting normal or abnormal extracellular matrix development. The identification of the molecular marker of the present invention enables the development of a range of diagnostic and therapeutic agents for degeneration of extracellular matrix or the poor development of the matrix at the fetal and postnatal stages including testing for mutations in the gene sequence in human disease such as but not limited to cartilage disease or arthritis. In a most preferred embodiment, the molecular marker is referred to herein as nullWARPnull for von Willebrand Factor A-Related Protein. The corresponding genetic form of WARP is referred to herein as nullWARPnull.
摘要:
We describe an improved method for generating sizable numbers of mature dendritic cells from nonproliferating progenitors in human blood. The first step or nullprimingnull phase is a culture of T cell depleted mononuclear cells in medium supplemented with GM-CSF and IL-4 to produce immature dendritic cells. The second step or nulldifferentiationnull phase requires the exposure to dendritic cell maturation factor such as monocyte conditioned medium. Using this two-step approach, substantial yields are obtained. The dendritic cells derive from this method have all the features of mature cells. They include a stellate cell shape, nonadherence to plastic, and very strong T cell stimulatory activity. The mature dendritic cells produced according to this invention are useful for activating T cells.

This invention comprises a novel approach to the assessment of antigen-specific T cells that quantitates and characterizes these cells with unprecedented clarity, and importantly, because it is performed in whole blood, is amenable to routine use in the clinical immunology laboratory. The methodology offers an improved flow cytometric intracellular cytokine assay in whole blood that can simultaneously measure multiple T cell subsets expressing multiple cytokines from a single whole blood culture. Evaluation of whole blood antigen specific cytokine responses has the important advantage of assessing T cell activation in the presence of ALL types of MHC autologous antigen presenting cells present in the native sample. It also has the advantage of enabling a culture system (whole blood) which can reflect effects of systemic environments (i.e. drug augmentation or suppression) on T cell responses to specific stimuli including antigen, by either culturing in the presence of such drug or analyzing the blood of a human or animal receiving such drug.
摘要:
A method for quantifying an HIV protease inhibitor in a sample includes combining HIV protease, a conjugate comprising an HIV protease inhibitor analog, and a sample suspected of containing an HIV protease inhibitor. The HIV protease and the conjugate are capable of forming a detectable complex. The method also includes measuring the amount of the detectable complex, and relating the amount of the detectable complex to a concentration of the HIV protease inhibitor in the sample.
摘要:
A novel polypeptide, oseteoprotegerin binding protein, involved in osteolcast maturation has been identified based upon its affinity for osteoprotegerin. Nucleic acid sequences encoding the polypeptide, or a fragment, analog or derivative thereof, vectors and host cells for production, methods of preparing osteoprotegerin binding protein, and binding assays are also described. Compositions and methods for the treatment of bone diseases such as osteoporosis, bone loss due to arthritis or metastasis, hypercalcemia, and Paget's disease are also provided.
