摘要:
The present invention relates to liquid formulations of poxvirus, in particular vaccinia virus, stable during storage. Such stable liquid formulations comprise a) a poxvirus, preferably a vaccinia virus, b) a pharmaceutically acceptable buffer, c) a monovalent salt, d) a pharmaceutically acceptable disaccharide or sugar alcohol, and e) a pharmaceutically acceptable chelating agent, wherein the pH of the formulation is comprised between 6.5 and 8.5.
摘要:
The invention relates to the field of molecular medicine. In particular, it relates to compositions and methods to enhance the clearance of aberrant cells, e.g. cancer cells or virus-infected cells, by the host's immune system. Provided is a composition comprising (i) a therapeutic compound that can trigger a host's immune effector cells against an aberrant cell, such as a therapeutic antibody, and (ii) at least one agent capable of reducing or preventing inhibitory signal transduction initiated via SIRPalpha.
摘要:
Compositions and methods for producing plant-derived immunogenic compositions that confer immunity against smallpox in a subject are provided. Plants engineered to produce antigenic proteins as well as expression cassettes comprising nucleic acids encoding proteins thereof are described. Methods of immunizing subjects with plant-derived compositions are also provided.
摘要:
The invention provides compositions, methods, and kits for the treatment or prevention of viral infections. The polyvalent (e.g., 2-valent) vaccines described herein incorporate computationally-optimized viral polypeptides that can increase the diversity or breadth and depth of cellular immune response in vaccinated subjects.
摘要:
The present invention relates to recombinant rhesus cytomegalovirus (RhCMV) and human cytomegalovirus (HCMV) vectors encoding heterologous antigens, such as pathogen-specific antigens or tumor antigens, which may be used, for example, for the treatment or prevention of infectious disease or cancer. The recombinant RhCMV or HCMV vectors elicit and maintain high level cellular immune responses specific for the heterologous antigen while including deletions in one or more genes essential or augmenting for CMV replication, dissemination or spread.
摘要:
The invention provides a recombinant or synthetic or engineered or non-naturally occurring poxvirus that contains and expresses DNA encoding a heterologous or exogenous antigen, epitope or immunogen and Flagellin or an operable binding portion thereof. The poxvirus can contain or be engineered to contain and express vaccinia host range gene K1L. The poxvirus can be attenuated as to mammals, e.g., NYVAC, NYVAC.1, NYVAC.2, avipox, canarypox, fowlpox, ALVAC, TROVAC, MVA, or MVA-BN. The invention also provides methods for inducing an immunological response involving the poxvirus, and compositions containing the poxvirus. The antigen, epitope or immunogen that the poxvirus expresses can be at least one Plasmodium antigen. The Plasmodium antigen(s), epitope(s) or immunogen(s) can be SERA, ABRA, Pfhsp70, AMA-1, Pfs25, Pfs16, CSP, PfSSP2, LSA-1 repeatless, MSA-1, AMA-1 or combination(s) thereof. Advantageously the poxvirus contains DNA coding for and expresses Plasmodium antigen(s) CSP, PfSSP2, LSA-1-repeatless, MSA-1, SERA, AMA-1 and Pfs25. Also, advantageously, the poxvirus is a NYVAC poxvirus. The invention thus also provides an anti-malarial immunogenic or immunological compositions comprising the poxvirus, and methods for inducing an immunogenic or immunological response against malaria or Plasmodium in a mammal comprising administering to the mammal the poxvirus or an immunological or immunogenic composition containing the poxvirus. The mammal can be a human.
摘要:
The present invention relates to compositions, methods, and uses involving the modulation of K4 protein activity, especially in the treatment of various diseases and in the enhancement of vaccination regimens. The invention relates to poxviruses having reduced or increased K4 protein activity, as well as methods of making and using these poxviruses. The invention further relates to K4 proteins and inhibitors of K4 protein activity, as well as methods for making and using them.
摘要:
Described herein are recombinant rhesus cytomegalovirus (RhCMV) and human cytomegalovirus (HCMV) vectors encoding heterologous antigens, such as pathogen-specific antigens or tumor antigens. The recombinant vectors elicit and maintain high level cellular and humoral immune responses specific for the heterologous antigen. The recombinant RhCMV and HCMV vectors may be used, for example, for the treatment or prevention of infectious disease or cancer. In some examples, the recombinant RhCMV or HCMV vectors may include deletions in genes encoding immunomodulatory proteins. In some examples, the recombinant RhCMV or HCMV vectors may be deficient or impaired in their ability to replicate within a cell, disseminate within the host or spread among hosts by including a deletion in one or more genes essential or augmenting for CMV replication, dissemination or spread.
摘要:
The invention provides gp38 polypeptides, which play a role in immunomodulation, nucleic acid molecules encoding these polypeptides, and therapeutic and diagnostic methods employing these polypeptides and nucleic acid molecules. The invention also provides methods for identifying compounds that modulate the biological activities of gp38 nucleic acid molecules and polypeptides, and therapeutic methods employing these compounds.
