Methods of producing bioconjugates of O-antigen polysaccharides covalently linked to a carrier protein using recombinant host cells are provided. The recombinant host cells used in the methods described herein encode a particular oligosaccharyl transferase enzyme depending on the O-antigen polysaccharide bioconjugate to be produced. The oligosaccharyl transferase enzymes can be PglB oligosaccharyl transferase or variants thereof. Also provided are compositions containing the bioconjugates, and methods of using the bioconjugates and compositions described herein to vaccinate a subject against extra-intestinal pathogenic E. coli. (ExPEC).

Disclosed are P. gingivalis antibodies raised against a chimeric or fusion protein, wherein the chimeric or fusion protein comprises a first peptide joined directly or through a linker to a second peptide or polypeptide, wherein (A) the first peptide comprises a region of a P. gingivalis trypsin-like enzyme and (B) the second peptide or polypeptide comprises an adhesin domain of P. gingivalis.

The invention relates to the field of minimal residual disease (MRD) diagnostics, which is progressively more applied for the evaluation of treatment effectiveness in patients with a hematological malignancy, such as B-cell precursor acute lymphoblastic leukemia (BCP-ALL), B-cell chronic lymphocytic leukemia (B-CLL), and multiple myeloma (MM). Provided are unique reagent compositions with carefully selected and thoroughly tested combinations of antibodies, for ≥8-color flow cytometric stainings as well as for 10-color and 12-color flow cyometric stainings, which can reach sensitivities of at least 10.sup.−4, even down to 10.sup.−5. Also provided are diagnostic kits and methods for detecting MRD.

The present invention relates to compositions and methods for the prevention and treatment of Borrelia infection. Particularly, the present invention relates to a polypeptide comprising a hybrid C-terminal fragment of an outer surface protein A (OspA), a nucleic acid coding the same, an antibody specifically binding the same, a pharmaceutical composition (particularly for use as a medicament or in a method of treating or preventing a Borrelia infection) comprising the polypeptide and/or the nucleic acid and/or the antibody, a method of treating or preventing a Borrelia infection and a method of immunizing a subject.

The invention provides methods and compositions for administration of allogeneic lymphocytes as an exogenous source of CD4+ T cell help for endogenous, tumor-reactive CD8+ T cells.

This disclosure provides cancer cell lysing agent, formulations comprising cancer cell lysing agent, and methods of using the same for treating cancer.

Described are vaccine compositions, methods of manufacture thereof, and methods of treating or preventing certain bacterial infections in humans and other mammals. For example, described are compositions comprising bacterial cell extracts that have undergone pretreatment such that lipid moieties have been cleaved from bacterial lipoproteins, thereby forming a vaccine composition that can stimulate a desired mammalian immune response while avoiding unwanted negative effects.

The present invention relates to a method for providing a neopeptide-specific T cell, wherein the neopeptide-specific T cell forms a complex having a half-life (T½) of at least 50 s with a neopeptide-MHC monomer. The present invention further relates to a T cell obtainable by the method as well as a pharmaceutical composition comprising such T cells.
