Microparticles with adsorbent surfaces, methods of making such microparticles, and uses thereof, are disclosed. The microparticles comprise a polymer, such as a poly(α-hydroxy acid), a polyhydroxy butyric acid, a polycaprolactone, a polyorthoester, a polyanhydride, and the like, and are formed using cationic, anionic, or nonionic detergents. The surface of the microparticles efficiently adsorb biologically active macromolecules, such as DNA, polypeptides, antigens, and adjuvants. Also provided are compositions of an oil droplet emulsion having a metabolizable oil and an emulsifying agent. Immunogenic compositions having an immunostimulating amount of an antigenic substance, and an immunostimulating amount of an adjuvant composition are also provided. Methods of stimulating an immune response, methods of immunizing a host animal against a viral, bacterial, or parasitic infection, and methods of increasing a Th1 immune response in a host animal by administering to the animal an immunogenic composition of the microparticles, and/or microemulsions of the invention, are also provided.

Oligonucleotides bearing free, uncapped 5′ phosphate group(s) are recognized by RIG-I, leading to the induction of type I IFN, IL-18 and IL-1β production. Bacterial RNA also induces type I IFN production. 5′ phosphate oligonucleotides and bacterial RNA can be used for inducing an anti-viral response or an anti-bacterial response, in particular, type I IFN and/or IL-18 and/or IL-1β production, in vitro and in vivo and for treating various disorders and diseases such as viral infections, bacterial infections, parasitic infections, tumors, allergies, autoimmune diseases, immunodeficiencies and immunosuppression. Single-stranded 5′ triphosphate RNA can be used for inducing an anti-viral response, an anti-bacterial response, or an anti-tumor response, in particular, type I IFN and/or IL-18 and/or IL-1β production, in a target cell-specific manner.

Compositions for treating parasitic infections and methods of using the compositions to treat subjects with parasitic infections are provided. Methods of selecting compositions for use in treating parasitic infections are further provided.

The invention provides compositions having Bacillus thuringiensis Crystal (Cry) proteins including transgenic plants expressing those proteins, and methods of using those proteins to prevent, inhibit or treat parasitic infections in plants and vertebrates.

A composition and method for immunization of mammals, containing antibodies from the eggs/egg yolks of chickens, or other suitable avian source, hyperimmunized against a selected pathogen(s) or immunogens, and a quantity of non-specific mammalian antibodies, such as those from commercial colostrum or serum products, which are combined to produce a composition that provides protection against the selected pathogen. Applications include viral, bacterial and parasitic infections.

The invention relates to compounds of the formula (I), which are L-enantiomeric forms of nucleoside analogues, and to pharmaceutical compositions containing the compounds, methods of treating certain diseases, including cancer, bacterial infection, parasitic infection, and T-cell mediated diseases, using the compounds, processes for preparing the compounds, and intermediates useful in the preparation of the compounds.

The invention provides uses and methods for alleviating respiratory tract symptoms of allergy, asthma, and of viral, bacterial, fungal and parasitic infections by shifting inappropriate TH2 responses to TH1 responses by administering IL-13 receptor-targeted immunotoxins to the respiratory tract.

Methods are described for improvement of the serum half life of therapeutic nucleic acids by 3′ conjugation to useful target proteins, or other large molecules with useful function. In one embodiment, a 3′ A, C or G overhang is added to ds-DNA and the primary amines conjugated using biocompatible bifunctional linkers to proteins. The resulting nucleic acid-3′-conjugates are serum nuclease-resistant and retained in vivo for long periods without rapid kidney clearance. Further, the choice of conjugate imparts additional functionality to the nucleic acid-3-conjugate. For example, if the protein in the DNA-protein conjugate is the first component of the complement cascade (Clq or Clqrs) and the DNA aptamer has been developed against surface components of a target cell, it can be used to treat bacterial or parasitic infections and cancers. If the protein is serum albumin or another common (nonimmunogenic) blood protein and the aptamer is directed against a toxin or venom, the aptamer-protein conjugate can be used as an antidote that binds and neutralizes the toxin or venom. Similar DNA (aptamer)-nanotube, -enzyme, and -toxin conjugates could also be used to target and selectively kill bacteria, parasites, and cancer cells in vivo. If the protein is an Fc antibody fragment or C3b protein from the complement system and the aptamer is developed against a bacterial cell capsular material, other cell surface component or viral cell surface component, then the aptamer-3′-protein conjugate can aid in opsonization of the target cells or viruses by phagocytic leukocytes.
