A nucleic acid probe for classification of pathogenic bacterial species is capable of collectively detecting bacterial strains of the same species and differentially detecting them from other bacterial species. Any one of the base sequences of SEQ ID NOS. 70 to 72 and complementary or modified sequences thereof or a combination of at least two of them is used for detecting the gene of an infectious disease pathogenic bacterium.

The present invention provides compositions and methods for modulating immune responses to antigens. One aspect of the present invention relates to a particle-based antigen delivery system (vaccination node) that comprises a hydrogel particle capable of both antigen presentation and DC activation. The VN may further comprise a chemoattractant-loaded microsphere capable of attracting DCs to the site of administration. Another aspect of the present invention relates to the use of the VN to modulate antigen presenting cells activation for the prevention and/treatment of various diseases, such as infectious diseases, cancers and autoimmune diseases.

Compositions and methods for reducing susceptibility to infectious disease in bees using RNA interference technology, and more particularly, prevention and treatment of viral infections in honeybees such as Israel acute paralysis virus (IAPV) by feeding of pathogen-specific dsRNA. Further, multiple-pathogen specific dsRNA is disclosed.

This invention relates to a vaccine and a method for immune activation which is effective for eliciting both a systemic, non-antigen specific immune response and a strong antigen-specific immune response in a mammal.

Also disclosed are therapeutic compositions useful in such a method.

The invention provides compositions and processes for the production of ordered and repetitive antigen or antigenic determinant arrays. The compositions of the invention are useful for the production of vaccines for the prevention of infectious diseases, the treatment of allergies and the treatment of cancers. Various embodiments of the invention provide for a core particle that is coated with any desired antigen in a highly ordered and repetitive fashion as the result of specific interactions.

The invention relates to isolated fully human monoclonal antibodies having specificity for human NKG2D and compositions thereof. The invention further relates to methods for using such antibodies in treating diseases or conditions such as cancer, autoimmune disease, or infectious disease.

The present invention provides for cellular compositions which facilitate engraftment of hematopoietic stem cells from a syngeneic, allogeneic or xenogeneic donor. The cellular compositions of the invention facilitate engraftment while minimizing the risk of graft versus host disease in the graft recipient. According to a preferred embodiment of the invention, a cell composition is provided, which cell composition comprises hematopoietic stem cells, such as CD34⁺ cells and/or facilitating cells, in combination with αβ TCR⁺ T cells. The invention also relates to methods of using the cellular compositions of the invention to induce donor specific tolerance in a recipient, thus allowing the transplantation of donor organs, cells and tissues. Also disclosed are methods of treating leukemia and cancer as well as infectious diseases caused by viruses.

A method for detecting one or more pathogens in a subject. The method includes the steps of: (a) procuring a biological sample, wherein the biological sample comprises nucleic acid material; (b) amplifying the nucleic acid material using random primers to produce a set of random amplicons; (c) providing one or more pathogen-specific probes or probe sets; (d) hybridizing the set of random amplicons with the one or more pathogen-specific probes or probe sets; and (e) determining selective hybridization between a random amplicon and a pathogen-specific probe or probe set, whereby the presence of a pathogen in a biological sample is detected.

Chimeric proteins are expressed, secreted or released by a bacterium to immunize against or treat a parasite, infectious disease or malignancy. The delivery vector may also be attenuated, non-pathogenic, low pathogenic, or a probiotic bacterium. The chimeric proteins include chimeras of, e.g., phage coat and/or colicin proteins, bacterial toxins and/or enzymes, autotransporter peptides, lytic peptides, multimerization domains, and/or membrane transducing (ferry) peptides. The active portion of the immunogenic chimeric proteins can include antigens against a wide range of parasites and infectious agents, cancers, Alzheimer's and Huntington's diseases, and have enhanced activity when secreted or released by the bacteria, and/or have direct anti-parasite or infectious agent activity. The activity of the secreted proteins is further increased by co-expression of a protease inhibitor that prevents degradation of the effector peptides. Addition of an antibody binding or antibody-degrading protein further prevents the premature elimination of the vector and enhances the immune response.

A nucleic acid probe for classification of pathogenic bacterial species is capable of collectively detecting bacterial strains of the same species and differentially detecting them from other bacterial species. Any one of the base sequences of SEQ ID NOS. 81 to 83 and complementary or modified sequences thereof or a combination of at least two of them is used for detecting the gene of an infectious disease pathogenic bacterium.

The invention relates to an anti-pollution portable gene detection method and device. The operation procedure comprises the steps that a PCR pipe containing amplification products is put into a device to conduct sealing, and by means of a series of simple manual operations, a detection result visible by eyes is obtained; target nucleic acid amplification products can be detected rapidly, nucleic acid amplification products can be prevented from being polluted, and a false positive result is avoided. Application can be achieved in the aspects of species identification on the gene level in the fields such as pathogen detection on clinical infectious diseases, food pathogenic microbe detection, agriculture, industry, customs and animal husbandry.

Methods and compositions for modulating interleukin-21 (IL-21)/IL-21 receptor (MU-1) activity using agonists or antagonists of IL-21 or IL-21 receptor (“IL-21R” or “MU-1”), are disclosed. IL-21/IL-21R antagonists can be used to induce immune suppression in vivo, e.g., for treating or preventing immune cell-associated pathologies (e.g., pathologies associated with aberrant activity of one or more of mature T cells (mature CD8+, mature CD4+ T cells), mature NK cells, B cells, macrophages and megakaryocytes, including transplant rejection and autoimmune disorders). IL-21/IL-21R agonists can be used by themselves or in combination with an antigen, e.g., as an adjuvant (e.g., a vaccine adjuvant), to up-regulate an immune response in vivo, e.g., for example, for use in treating cancer and infectious disorders.
