Abstract:
The invention is related to recombinantly produced fusion polypeptides comprising antibody V.sub.H and V.sub.L sequences operatively linked to a .beta.-lactamase for use in the delivery of cytotoxic drugs to tumor cells.
Abstract:
This invention provides purified antigens which are indicative of the presence of atherosclerotic plaque. Different concentrations of these antigens have been found to coincide with the progression of atherosclerosis. The subject invention also provides different hybridoma cell lines which produce monoclonal antibodies directed to antigens associated with atherosclerosis and a hybridoma cell line which produces monoclonal antibodies directed to antigen associated with normal artery and not with plaque. The atherosclerotic plaque antigen, and monoclonal antibodies made thereto, are used in various methods for detecting in a biological sample an antigen present in, and indicative of the presence of, atherosclerotic plaque. The monoclonal antibodies are also used in methods of imaging atherosclerotic plaque, and treating atherosclerosis. The methods of treating atherosclerosis include a method of digesting atherosclerotic plaque with enzymes, and a method of ablating atherosclerotic plaque using radiation. The subject invention also provides a method of treating atherosclerotic plaque by directly delivering a drug to the plaque. The subject invention further provides a method for treating atherosclerosis by blocking the synthesis of atherosclerotic plaque or by blocking binding of antibodies to the antigen.
Abstract:
The invention is directed to the treatment of degenerative diseases of tissues which have lost melanin and which share a common embryological basis as tissues of the nervous system by the administration of an active substance which causes an increased concentration of melanin in the tissue. Such active substances include melanin, melanin variants, melanin analogs, melanin derivatives, tyrosinase, tyrosinase gene, melanin-concentrating hormone and combinations thereof. Examples. of such diseases include Parkinson's disease, Alzheimer's disease, retinitis pigmentosa, schizophrenia and dementia. The invention is also useful in assisting in the repair of neurons in a mammal having neuron damage by administering an effective amount of an active substance which causes an increased concentration of melanin in the neuron to aid in nerve repair. The invention is further useful in protecting a mammal from a toxin-induced disease or from the adverse effects of a toxin by administering an effective amount of the active substance described above.
Abstract:
The subject invention relates to a fibrin-specific monoclonal antibody wherein said monoclonal antibody does not crossreact with: (a) fibrinogen, (b) plasmin derived fibrinogen degradation products and (c) plasmin derived fibrin degradation products.
Abstract:
Disclosed herein are methods and compositions comprising anti-CD74 and/or anti-HLA-DR antibodies for treatment of GVHD and other immune dysfunction diseases. In preferred embodiments, the anti-CD74 and/or anti-HLA-DR antibodies are effective to deplete antigen-presenting cells, such as dendritic cells. Most preferably, administration of the therapeutic compositions depletes all subsets of APCs, including mDCs, pDCs, B cells and monocytes, without significant depletion of T cells. In alternative embodiments, administration of the therapeutic compositions suppresses proliferation of allo-reactive T cells, while preserving cytomegalovirus (CMV)-specific, CD8+ memory T cells. The compositions and methods provide a novel conditioning regimen for preventing aGVHD and/or treating chronic GVHD, without altering preexisting anti-viral immunity.
Abstract:
This invention is directed to water soluble protein polymer conjugates which are stabile in hostile environments. The conjugate comprises a protein which is linked to an acrylic polymer at multiple points through saccharide linker groups.
Abstract:
An antibody fragment able to bind to a target site is prolonged by an additional peptide. The Therapeutic agent is bound to this peptide or means are provided to bring about such binding. The antibody fragment and possibly also the therapeutic agent are included in a product so that binding to the target site delivers the therapeutic agent to the vicinity. The product may for example be for dental care, such as a toothpaste or mouthwash and the antibody fragment may then bind to a component of dental plaque.
Abstract:
Novel multi-component conjugates are provided having at least two components which are superoxide dismutase and catalase. Novel therapeutic agents utilising these conjugates are provided which are effective to reduce harmful levels of superoxide and hydroxyl free radicals in body tissues.
Abstract:
Disclosed is a method for the in vivo lysis of a thrombus in a host by administration of a conjugate consisting of a monoclonal antibody specific for fibrin coupled to a plasminogen activator such as tissue plasminogen activator, urokinase or streptokinase.
Abstract:
A fibrinolytically active protein conjugate comprising at least one optionally blocked fibrinolytic enzyme linked by way of a site other than the catalytic site responsible for fibrinolytic activity to at least one human protein.Processes from making the conjugates and pharmaceutical compositions containing them are also described.
