The present invention relates to an immunogenic complex comprising an amino acid sequence having at least 80% sequence identity with the amino acid sequence of the N-terminal region of a group B Streptococcus surface protein, and a capsular polysaccharide. The immunogenic complex is capable of eliciting protective immunity against group B Streptococcus. The invention further pertains to an immunogenic product comprising the immunogenic complex and an immunogenic fusion protein, the vaccine, the immunogenic complex, or the immunogenic product for use in a method of preventing or treating a group B Streptococcus infection, as well as a method of preventing or treating a group B Streptococcus infection.

Technologies for the prevention and/or treatment of pneumococcal infections.

The present disclosure relates generally to methods and compositions for modulating frataxin (FXN) expression, e.g., to treat Friedreich ataxia (FRDA).

The present application is generally directed to novel pneumococcal polypeptide antigens and nucleic acids encoding such antigens, and immunogenic compositions comprising such antigens for treating and preventing pneumococcal infection. The present invention further provides method of using the antigens to elicits an immune response (e.g., IL-17A response, a T cell-mediated and/or B-cell-mediated immune responses). The present invention also provides methods of prophylaxis and/or treatment of pneumococcal-mediated diseases, such as sepsis, comprising administering an immunogenic composition including one or more of a combination of pneumococcal antigens or functional fragments thereof as disclosed herein. In some embodiments, one or more pneumococcal antigens can be present in a polysaccharide conjugate. The compositions induce an anti-pneumoccocus immune response when administered to a mammal. The compositions can be used prophylactically to vaccinate an individualand/or therapeutically to induce a thereapeutic immune response to an infected individual.

The present disclosure relates generally to methods of preparing glycoconjugates containing a saccharide conjugated to a carrier protein by use of stable nitroxyl radical related agent/oxidant as an oxidizing agent, to immunogenic compositions comprising such glycoconjugates, and to methods for the use of such glycoconjugates and immunogenic compositions.

The methods and compositions described herein surprisingly increase CRISPR/Cas-mediated gene editing in stem cells by transiently treating the cells with a stem cell viability enhancer prior to and/or after contacting the cells with one or more CRISPR/Cas9 components. Further, this treatment also surprisingly results in increased engraftment of the stem cells into the target tissue of a subject. The present disclosure also provides one or more modified CRISPR/Cas9 components which, when used in combination with the stem cell viability enhancer, further increases the frequency of gene editing in stem cells, increases stem cell viability, and increases stem cell engraftment.

Quorum-sensing peptides are provided as diagnostic biomarkers, and quorum-sensing peptide inhibiting substances are provided for use in the treatment of metastasis of colorectal cancer in a subject, in particular a human subject. Methods for reducing metastasis of colorectal cancer in a subject include administering to the subject a microorganism that reduces or blocks activity of a pro-metastatic quorum-sensing peptide or a metabolite thereof present in a gastrointestinal tract or blood of the subject; and/or that reduces or blocks production of the pro-metastatic quorum-sensing peptide or the metabolite thereof in the gastrointestinal tract or blood of the subject. The pro-metastatic quorum-sensing peptide may include EntF or the metabolite EntF* of EntF.
