Abstract: Disclosed herein are peptide fragments derived from netrin-1 and compositions thereof and methods of using thereof. In some embodiments, the present invention provides a peptide that is 8-65 amino acid residues long and has a core sequence having Formula I as follows: CX(1-2)CX(3-4)TX(0-1)G, wherein X is any amino acid residue. In some embodiments, the present invention provides a composition comprising one or more peptides of the present invention which have a core sequence according to Formula I, Formula IA, or Formula IB.
Abstract: The invention relates to polypeptides, and in particular to polypeptides that are capable of inhibiting the activity or activation of the complement system. It also relates to nucleic acids that encode the polypeptides and to uses of the polypeptides. The complement system helps or “complements” the ability of antibodies and phagocytic cells to clear pathogens from an organism. It forms part of the innate immune system. Down-regulation of complement activation has been demonstrated to be effective in treating several disease indications in animal models and in ex vivo studies. The present invention provides novel polypeptides that can be used for the treatment of diseases or disorders that relate to inappropriate activation of one or more of the complement pathways.

Abstract: The present invention provides antibodies that bind to the cat allergen, Fel d1, compositions comprising the antibodies, nucleic acids encoding the antibodies and methods of use of the antibodies. According to certain embodiments of the invention, the antibodies are fully human antibodies that bind to Fel d1. The antibodies of the invention are useful for binding to the Fel d1 allergen in vivo, thus preventing binding of the Fel d1 allergen to pre-formed IgE on the surface of mast cells or basophils. In doing so, the antibodies act to prevent the release of histamine and other inflammatory mediators from mast cells and/or basophils, thus ameliorating the untoward response to the cat allergen in sensitized individuals. The antibodies of the invention may also be useful for diagnostic purposes to determine if a patient is allergic to the Fel d1 cat allergen.

Abstract: Various processes are disclosed for producing nanocellulose materials following steam extraction or hot-water digestion of biomass. Processes are also disclosed for producing nanocellulose materials from a wide variety of starting pulps or pretreated biomass feedstocks. The nanocellulose materials may be used as rheology modifiers in many applications. Water-based and oil-based drilling fluid formulations and additives are provided. Also, water-based and oil-based hydraulic fracturing fluid formulations and additives are provided. In other embodiments, polymer-nanocellulose composites are provided.
Abstract: Processes disclosed are capable of converting biomass into high-crystallinity nanocellulose with surprisingly low mechanical energy input. In some variations, the process includes fractionating biomass with an acid (such as sulfur dioxide), a solvent (such as ethanol), and water, to generate cellulose-rich solids and a liquid containing hemicellulose and lignin; and mechanically treating the cellulose-rich solids to form nanofibrils and/or nanocrystals. The crystallinity of the nanocellulose material may be 80% or higher, translating into good reinforcing properties for composites. The nanocellulose material may include nanofibrillated cellulose, nanocrystalline cellulose, or both. In some embodiments, the nanocellulose material is hydrophobic via deposition of some lignin onto the cellulose surface. Optionally, sugars derived from amorphous cellulose and hemicellulose may be separately fermented, such as to monomers for various polymers.
