摘要:
Monoclonal IgM antibodies which promote central nervous system remyelination when given to a mammal afflicted with a demyelinating disease are disclosed. These antibodies show multi-organ autoreactivity, and recognize both surface and cytoplasmic determinants on glial cells.
摘要:
An analog of human amyloid plaque core protein protease inhibitor wherein the amino acid corresponding to arginine at position 13 in the sequence is substituted with an aromatic amino acid, said analog exhibiting chymotrypsin inhibitory activity or is substituted with a neutral hydrophobic amino acid, said analog exhibiting human elastase inhibitory activity and method of producing them. Use of the protease inhibitor in the manufacture of a medicament for use in treating acute pancreatitis and method of recovering purified protease inhibitor.
摘要:
A novel neurotrophic factor referred to as glial derived neurotrophic factor (GDNF) has been identified and isolated from serum free growth conditioned medium of B49 glioblastoma cells. Rat and human genes encoding GDNF have been cloned and sequenced. A gene encoding GDNF has been subcloned into a vector, and the vector has been used to transform a host cell in order to produce biologically active GDNF in a recombinant DNA process.
摘要:
The present invention relates to a method for diagnosing Alzheimer's disease and Parkinson's disease in a subject by analyzing the expression of Semaphorin 3 and downstream effectors. It also provides a method for identifying a substance useful in the prevention or treatment of Alzheimer's disease and Parkinson's disease, and a method of using such substance in the treatment of Alzheimer's disease and Parkinson's disease.

摘要:
Growth hormone polymeric controlled release systems are described wherein the growth hormone retains good biological activity and is released over an extended period of time following administration by injection. In the preferred embodiment, human growth hormone polymeric microspheres are made using very cold temperatures to freeze the polymer-growth hormone mixtures into polymeric microspheres with very high retention of biological activity and material. Sustained release of biologically active growth hormone is achieved when the microspheres are tested in vivo , extending over a period of greater than one day to several months. Altered release can be achieved by inclusion of degradation modifiers, pore forming agents, and stabilizers of the growth hormone.
摘要:
The present invention provides a substantially purified fragment of a Serrate protein, which is characterized by the ability in vitro, when expressed on the surface of a first cell, to bind to a Notch protein expressed on the surface of a second cell, as well as derivatives and analog of this fragment able to bind to a second protein selected from the group consisting of a Notch, a Delta and a Serrate protein. The nucleic acid sequence encoding said protein as well as vectors and recombinant cells containing the same are described. A method of producing a fragment of a Serrate protein is also disclosed.
