Immunogenic compositions comprising a recombinant adenoviral vector that expresses a nucleic acid molecule encoding multimers of a Gonadotrophic Releasing Hormone (GnRH), an antigenic carrier and multiple immune enhancing epitopes are described herein. The use of the immunogenic compositions on mammals resulting in an antibody response to GnRH can inhibit the physiological activity of GnRH and thus induce infertility and modify breeding behavior of immunized animals.

The present invention provides a mutant CD83 promoter comprising the promoter/enhancer regions of human CD83 promoter and being dendritic cell-specific, and the use thereof, specifically for the treatment or prevention of diseases or medical conditions related to malignancy, autoimmunity or prevention of transplant rejections.

The present invention provides a particle comprising a fusion protein, wherein the fusion protein comprises at least one NANP repeat (SEQ ID NO: 7), some or all of the C-terminus of the CS protein from Plasmodium falciparum and a hepatitis B surface antigen, and wherein the particle comprises no, or substantially no, free hepatitis B surface antigen protein, and uses thereof.

The present invention provides compositions, vaccines and methods for inducing protective immunity against filovirus infection, particularly protective immunity against infection of one or more subtypes of Ebola viruses and Marburg virus.

This document provides adenovirus vectors and methods and materials related to using adenovirus vectors. For example, adenoviruses for delivering nucleic acid encoding one or more immunogens (e.g., one or more immunogens associated with a pathogen causing an infection) to cells within a mammal such that the mammal produces an effective immune response against the immunogen(s) are provided.

The invention relates to biotechnology, immunology and virology and, in particular, to an immunobiological agent for the prevention of diseases caused by severe acute respiratory syndrome virus SARS-CoV-2. Also, a method of inducing specific immunity to the SARS-CoV-2 virus is disclosed, comprising the administration to mammals of one or more immunobiological agents for the prevention of diseases caused by severe acute respiratory syndrome virus SARS-CoV-2. The invention facilitates an effective induction of the immune response to the SARS-CoV-2 virus.

The invention is based on the disclosure provided herein that secondary lymphoid organ chemokine (SLC) inhibits the growth of syngeneic tumors in vivo. Thus, the invention provides a method of treating cancer in a mammal subject by administering a therapeutically effective amount of an SLC to the mammal in combination with a checkpoint inhibitor, including monoclonal antibodies and small molecule inhibitors. Exemplary checkpoint molecules include CTLA-4, a CTLA-4 receptor, PD-1, PD1-L1, PD1-L2, 4-1BB, OX40, LAG-3, TIM-3 or a combination thereof. SLCs useful in the methods of the invention include SLC polypeptides, variants and fragments and related nucleic acids.

An optimized coding sequence of human blood clotting factor eight (VIII) and a promoter may be used in vectors, such as rAAV, for introduction of factor VIII, and/or other blood clotting factors and transgenes. Exemplary of these factors and transgenes are alpha-1-antitrypsin, as well as those involved in the coagulation cascade, hepatocye biology, lysosomal storage, urea cycle disorders, and lipid storage diseases. Cells, vectors, proteins, and glycoproteins produced by cells transformed by the vectors and sequence, may be used in treatment.

Disclosed herein are compositions and methods for treating cancer in a subject. This involves administering an oncolytic virus containing a heterologous DNA sequence encoding one or more immunomodulatory and/or immunostimulatory polypeptide(s) of interest to the subject under conditions effective to enhance an anti-tumor immune response in the subject, and to treat cancer. It also relates to a method of enhancing the delivery to and distribution within a tumor mass of therapeutic viruses.

The present disclosure provides formulations and therapies for treating subjects with elevated levels of TIM-3 using gene-based cytotoxic immunostimulant therapy alone or with other immunotherapies.
