Abstract:
Provided herein are methods for using compositions that include a fusion protein having a YscF protein domain, a mature F1 protein domain, and a LcrV protein domain. In one embodiment the composition is used to confer immunity to plague, such as pneumonic plague, caused by Yersinia pestis. In one embodiment, the composition is administered to a mucosal surface, such as by an intranasal route. In one embodiment, the administration to a mucosal surface includes a vector that has a polynucleotide encoding a fusion protein, where the fusion protein includes a YscF protein domain, a mature F1 protein domain, and a LcrV protein domain. The administration is followed by a second administration by a different route, such as an intramuscular route. The second administration includes a fusion protein having the same three domains, and in one embodiment the fusion protein is the same one administered to a mucosal surface.
Abstract:
The present invention relates to peptides, particularly human monoclonal antibodies, that bind specifically to poly-N-acetyl glucosamine (PNAG), such as Staphylococcal PNAG, in acetylated, partially acetylated and/or fully deacetylated form. The invention further provides methods for using these peptides in the diagnosis, prophylaxis and therapy of infections by bacteria that express PNAG such as but not limited to Staphylococci and E. coli. Some antibodies of the invention enhance opsonophagocytic killing and in vivo protection against bacteria that express PNAG such as but not limited to Staphylococci and E. coli. Compositions of these peptides, including pharmaceutical compositions, are also provided, as are functionally equivalent variants of such peptides.
Abstract:
A modified Herpes Simplex Virus (HSV), which has a portion of gD (glycoprotein D) of the glycoproteic envelope deleted and a heterologous single chain antibody inserted in place of such deleted portion; the modified HSV is capable of infecting cells through receptor HER2/ErbB2 but not through receptors HVEM/HveA and nectin1/HveC; uses of the modified HSV and a process of the preparation thereof are also disclosed.
Abstract:
The present invention is directed to methods for administering antigenic material to a patient as a vaccine against an infection comprising providing both an antigenic material specific to the desired immunological response desired plus an adjuvant comprised of a peptide of a sequence derived from the sequence of pneumococcal surface adhesin A protein (PsaA). Preferably the peptide comprises a sequences derived from one or more sequences of PsaA that contain the epitope regions or contiguous amino acids of SEQ ID NOs 1 or 2. The invention is also directed to vaccine compositions containing adjuvant of the invention and also adjuvant compositions of the invention.
Abstract:
Provided herein is a genetically modified Y. pestis that includes three alterations compared to a control Y. pestis. Two alterations include decreased mRNA, decreased protein, or a combination thereof, encoded by a lpp coding region and encoded by a msbB coding region. The third alteration is selected from an alteration of an intergenic region between the coding regions ypo1119 and ypo1120, and decreased mRNA, decreased protein, or a combination thereof, encoded by a coding region selected from pla, ypol717, ypmt1.80c, rbsA (ypo2500), ypo0498, vasK (ypo3603), ypo3164, hxuB (ypo3248), ypo1616, ypo1119, ypo1120, and ail. Also provided are compositions that include the genetically modified Y. pestis, and methods of using the genetically modified Y. pestis.

Abstract:
Embodiments of the present invention generally disclose methods, compositions and uses for generating and expressing enterobacterial-associated peptides. In some embodiments, enterobacterial-associated peptides include, but are not limited to plague-associated peptides. In certain embodiments, methods generally relate to making and using compositions of constructs including, but not limited to, attenuated or modified vaccinia virus vectors expressing enterobacterial-associated peptides. In other embodiments, vaccine compositions are reported of use in a subject.
Abstract:
Described herein are microorganisms that are modified so that they have an increased ability to be recognized by the innate immune system of a eukaryote, relative to an unmodified microorganism. A microorganism may be a gram-negative bacterium that has been modified to produce high potency lipopolysaccharide, e.g., Yersinia pestis expressing LpxL. Such modified microorganisms may be used as vaccines for protection against an infection by the unmodified microorganism. They may also be used as delivery vehicles of one or more heterologous antigens, e.g., antigens from pathogens or those associated with a hyperproliferative eukaryotic cell.
