Antifungal and antibacterial peptides

Methods for treating cystic fibrosis in a mammal that include administering to the mammal an effective amount of a histatin, a histatin fragment, or a histatin-related peptide are disclosed.

Method for treating cystic fibrosis

The present invention pertains to chimeric antibodies that are reactive with transferrin receptors on brain capillary endothelial cells. These antibodies are composed of a variable region, immunologically reactive with the transferrin receptors, that is obtained from one animal source, and a constant region that is derived from an animal source other than the one that provided the variable region. These chimeric antibodies can exist either as isolated entities or as conjugates with a neuropharmaceutical agent for transferal across the blood brain barrier.

Transferrin receptor reactive chimeric antibodies

Periodontal disease can be treated by the administration of metal ions, preferably silver ions, to the site where the microorganisms that cause this disease reside. Administration can be to periodontal pockets or adjacent to exposed tooth roots or alveolar bone during periodontal surgical procedures. The metal ions can be administered in polymeric microparticles, deformable films or microparticles embedded within deformable films. The metal ions are particularly microbiocidal to the bacterial pathogens that are the causative agents of periodontal disease.

Use of locally delivered metal ions for treatment of periodontal disease

The present invention pertains to a method for delivering a neuropharmaceutical or diagnostic agent across the blood brain barrier to the brain of a host. The method comprises administering to the host a therapeutically effective amount of an antibody-neuropharmaceutical or diagnostic agent conjugate wherein the antibody is reactive with a transferrin receptor and the antibody is a chimera between the variable region from one animal source and the constant region from a different animal source. Other aspects of this invention include a delivery system comprising an antibody reactive with a transferrin receptor linked to a neuropharmaceutical or diagnostic agent and methods for treating hosts afflicted with a disease associated with a neurological disorder.

Anti-fungal and anti-bacterial histatin-based peptides

Anti-fungal D-amino acid histatin-based peptides

The present invention pertains to a method for delivering a neuropharmaceutical or diagnostic agent across the blood brain barrier to the brain of a host. The method comprises administering to the host a therapeutically effective amount of an antibody-neuropharmaceutical or diagnostic agent conjugate wherein the antibody is reactive with a transferrin receptor. Other aspects of this invention include a delivery system comprising an antibody reactive with a transferrin receptor linked to a neuropharmaceutical or diagnostic agent and methods for treating hosts afflicted with a disease associated with a neurological disorder.

The present invention pertains to a method for delivering a neuropharmaceutical agent across the blood brain barrier to the brain of a host. The method comprises administering to the host a therapeutically effective amount of a ligand-neuropharmaceutical agent fusion protein wherein the ligand is reactive with a brain capillary endothelial cell receptor. Other aspects of this invention include a delivery system comprising a ligand reactive with a brain capillary endothelial cell receptor which has formed a fusion protein with a neuropharmaceutical agent. The fusion proteins are also aspects of this invention.
