Abstract:
The present invention discloses a conjugate comprising an antigen (for example a saccharide antigen) covalently linked to a Pseudomonas aeruginosa PcrV carrier protein comprising an amino acid sequence which is at least 80% identical to the sequence of SEQ ID NO:1-4, wherein the antigen is linked (either directly or through a linker) to an amino acid residue of the P. aeruginosa PcrV carrier protein. The invention also discloses Pseudomonas aeruginosa PcrV proteins that contain glycosylation site consensus sequences.

Abstract:
The present invention is in the field of pneumococcal capsular saccharide conjugate vaccines. Specifically, the present invention relates to sized Streptococcus pneumoniae serotype 6A capsular polysaccharides, in particular Streptococcus pneumoniae serotype 6A capsular polysaccharides having the average size (e.g. M w ) of the Streptococcus pneumoniae serotype 6A capsular polysaccharide is between 100-1000 kDa, suitably conjugated to a carrier protein.
Abstract:
Compositions including chitosan covalently linked to a cytokine or growth factor are provided herein. The compositions can be used to produce pharmaceutical compositions and can be used in methods of treating a variety of diseases or disorders. The compositions are especially suitable for localized delivery and may allow for intratumoral delivery and treatment of cancers or stimulation of an immune response to a co-administered antigen.
Abstract:
Compositions and methods are described for inducing an immune response against extra-intestinal pathogenic Escherichia coli (ExPEC) to thereby provide immune protection against diseases associated with ExPEC. In particular, compositions and methods are described for using conjugates of E. coli polysaccharide antigens O25B, O1A, O2, and O6A covalently bound to a detoxified exotoxin A of Pseudomonas aeruginosa (EPA) carrier protein as vaccines for the prevention of invasive ExPEC disease caused by ExPEC serotypes O1A, O2, O6A and O25B.
Abstract:
Engineered bacteria are provided that produce modified lipid A and a polypeptide or polysaccharide antigens. In some aspects, immunogenic compositions are provided comprising a modified a lipid A and a polypeptide or polysaccharide antigen.
Abstract:
Some aspects of this disclosure provide engineered exopolysaccharide-associated proteins, engineered bacteria expressing such proteins, and engineered biofilms comprising such proteins. Some aspects of this disclosure provide methods for engineering exopolysaccharide-associated proteins, and for the generation of engineered bacteria and biofilms expressing or comprising such proteins. Some aspects of this disclosure provide compositions and methods useful for the generation of vaccines and the vaccination of subjects, for delivering molecules of interest to a target site, for example, a surface, for purification of molecules of interest, for example, from bioreactors comprising engineered bacteria as provided herein, and for bioremediation applications, such as the cleanup of environmental pollutants.
Abstract:
A method for constructing a compound of immunologically modified nanotubes and method for using the compound to deliver immunoadjuvants to tumor cells and to produce targeted, synergistic photophysical and immunological reactions for cancer treatment. To prepare the immunologically modified nanotubes, carbon nanotubes are dissolved in a solution of glycated chitosan, an immunostimulant, hence using glycated chitosan as a surfactant for rendering the aqueous solution of nanotubes stable. The compound can be used for treatment of cancer. The method includes steps of intratumorally administering immunologically modified nanotubes and administering laser irradiation of the target tumor. The nanotube serves as a carrier to deliver immunoadjuvants to the tumor cells and serves as a light-absorbing agent in a cell body of a tumor in a host. Upon laser irradiation of target tumor cells, immunologically modified nanotubes inside the tumor cells can produce spatially and temporally synchronized photothermal and immunological reactions for cancer treatment.
Abstract:
