Abstract: Cloned recombinant or synthetic DNA sequences related to the pathology of Alzheimer's disease are injected into fertilized mouse eggs. The injected eggs are implanted in pseudo pregnant females and are grown to term to provide transgenic mice whose cells express proteins related to the pathology of Alzheimer's disease. The injected sequences are constructed having promoter sequences connected so as to express the desired protein in brain tissues of the transgenic mouse. The proteins which are preferably ubiquitously expressed include (1) .beta.-amyloid core precursor proteins; and (2) .beta.-amyloid related precursor proteins; and (3) serine protease inhibitor. The transgenic mice provide useful models for studying compounds being tested for their usefulness in treating Alzheimer's disease, and for studying the in vivo interrelationships of these proteins to each other.

Abstract: A novel hydrophobic surfactant-associated protein mixture, i.e., a SAP-6 proteins, has been isolated from pulmonary animal tissue. A small, novel pulmonary hydrophobic surfactant-associated SAP-6-Val protein having a molecular weight of about 6,000 daltons as determined by SDS-PAGE and about 3,500-4,000 daltons as determined by tricine-SDS-PAGE has been further isolated from the SAP-6 protein mixture. The amino acid residue compositions of the SAP-6-Val protein for human and bovine have been determined and disclosed. When a SAP-6-Val protein is combined with phospholipids, it enhances the surfactant-like activity of the phospholipids in lungs of animals and, therefore, uniquely imparts to the mixture significant pulmonary biophysical activity. Such a mixture results in enhanced adsorption of the phospholipids with properties similar to that of natural pulmonary surfactant material.

Abstract: The substitution of the L-Pro at the 7-position of the peptide hormone bradykinin or other substituted analogs of bradykinin with a D-configuration hydroxyproline ether or thioether converts bradykinin agonists into bradykinin antagonists. The invention further includes the intermediate compounds and additional modifications at other positions within the novel 7-position modified bradykinin antagonists which increase enzyme resistance, antagonist potency, and/or specificity of the new bradykinin antagonists. The analogs produced are useful in treating conditions and diseases of a mammal and human in which an excess of bradykinin or related kinins are produced or injected such as by insect bites.

Abstract: An improved method for expressing peptides as fusion proteins, uses a carrier for a heterologous peptide to provide a fusion protein having a high pI. The high isoelectric point facilitates separation of the fusion protein from all other host cell proteins, and separation of the carrier from the peptide after cleavage.
