Abstract: The present invention relates to a fermentation medium for cultivating Corynebacterium diphtheriae. The present invention also relates to the use of the fermentation medium in processes for obtaining diphtheria toxin from the Corynebacterium diphtheriae bacteria being cultivated and the preparation of vaccines using the diphtheria toxin obtained in the processes. The present invention further relates to a purification and detoxification processes specifically adapted for preparing a diphtheria toxoid for inclusion into a vaccine.

Abstract: The present invention provides, among other aspects, methods for the manufacture of plasma-derived immunoglobulin G compositions highly enriched for anti-brain disease related protein antibodies (e.g., anti-A?, anti-RAGE, and anti-?-synuclein antibodies). Advantageously, the methods provided do not affect the manufacturing processes or capabilities for producing plasma-derived IgG therapeutics. Plasma-derived IgG compositions that are highly enriched for anti-brain disease related protein antibodies (e.g., anti-A?, anti-RAGE, and anti-?-synuclein antibodies), as also provided here. Methods for the treatment of brain diseases and disorders by administration of plasma-derived IgG compositions highly enriched for anti-brain disease related protein antibodies (e.g., anti-A?, anti-RAGE, and anti-?-synuclein antibodies), are also provided.

Abstract: The present invention provides compositions including siderophore receptor polypeptides and porins from gram negative microbes, and preferably, lipopolysaccarhide at a concentration of no greater than about 10.0 endotoxin units per milliliter. The present invention also provides methods of making and methods of using such compositions.

Abstract: A device that includes a scaffold composition and a bioactive composition with the bioactive composition being incorporated therein or thereon, or diffusing from the scaffold composition such that the scaffold composition and/or a bioactive composition captures and eliminates undesirable cells from the body a mammalian subject. The devices mediate active recruitment, sequestration, and removal or elimination of undesirable cells from their host.

Abstract: Disclosed are methods of stimulating in a subject an immune response to an antigen to which the immune response is targeted. This method includes the step of administering to the subject a binding agent which binds a surface receptor of an antigen-presenting cell, in some instances without being blocked substantially by the natural ligand for the surface receptor, and an antigen to which the immune response is targeted, in a physiologically acceptable medium to the subject. Also disclosed are molecular complexes including the binding agent coupled to an antigen.
