摘要:
Provided are immunogenic compositions based on the highly conserved, core CD4 binding site of the gp120 protein of the human immunodeficiency virus. One embodiment includes an antigenic conjugate of an electophilic derivative of HIV gp120 peptide 416-433, designated E-416-433, covalently linked to an immunogenic carrier protein. The compositions are effective in stimulating the production of HIV neutralizing antibodies in mammals. Provided also are related methods of immunization, methods of antibody production and antibodies obtained using the methods of the invention.
摘要:
Covalently reactive antigen analogs are disclosed herein. The antigens of the invention may be used to stimulate production of catalytic antibodies specific for predetermined antigens assocated with particular medical disorders. The antigen analogs may also be used to permanently inactivate endogenously produced catalytic antibodies produced in certain autoimmune diseases as well as in certain lymphoproliferative disorders.
摘要:
A catalytic antibody and components thereof which cleave HIV gp120 are disclosed. Methods of isolating, cloning and purifying such antibodies or antibody components from patients are also described. The compositions described may provide utility in the treatment of HIV infection.
摘要:
Catalytic antibody components, methods for producing catalytic antibody components, methods for using catalytic antibody components, in particular, single chain and smaller components are disclosed. Catalytic antibody components able to promote the cleavage or formation of an amide, peptide, ester or glycosidic bond, and which are prepared from monoclonal catalytic antibodies, catalytic autoantibodies or by site-directed mutagenesis are disclosed. Methods of using catalytic antibody components alone or in combination with other antibody components or other biological moieties are disclosed.
摘要:
The present invention describes the composition of class and subclass selected pooled human immunoglobulins with catalytic activity, methods of preparation thereof, and therapeutic utility thereof.
摘要:
Disclosed are monoclonal antibodies and antibody fragments which recognize antigens encoded by HERV DNA sequences, and methods for production, including recombinant antibody fragments derived from lymphoid cells of lupus patients that make antibodies which neutralize HIV.
摘要:
What is disclosed is a catalytic monoclonal antibody able to cleave a polypeptide and in particular, a catalytic monoclonal antibody elicited by a ground state antigen is disclosed. Antigens include, among others, the polypeptide, a derivative of the polypeptide, a fragment of the polypeptide or any of these bound to a carrier molecule. Methods of making and using the catalytic monoclonal antibody are also disclosed.
摘要:
Autoantibodies which enhance the rate of a chemical reaction of a substrate, processes for their preparation, their use and compositions thereof are disclosed. In particular, an autoantibody capable of catalyzing the hydrolysis of the peptide bond between amino acid residues 16 and 17 in the neurotransmitter vasoactive intestinal peptide (VIP) is disclosed.
摘要:
Specific, selective inhibitors of catalytic antibodies both synthetic and naturally occurring, their use and compositions thereof are disclosed. In particular, an inhibitor preventing the hydrolysis of the peptide bond between amino acid residues 16 and 17 in the neurotransmitter vasoactive intestinal peptide (VIP) by an anti-VIP catalytic autoantibody is disclosed.
