Described herein are single-domain antibodies that might serve as alternatives to conventional monoclonal antibodies for either the detection or treatment of Venezuelan equine encephalitis virus (VEEV).

Disclosed are antigen binding polypeptides and antigen binding polypeptide complexes (e.g., antibodies and antigen binding fragments thereof) having certain structural features. Also disclosed are polynucleotides and vectors encoding such polypeptides and polypeptide complexes; chimeric antigen receptors (CARs), cells, pharmaceutical compositions and kits containing such polypeptides and polypeptide complexes; and methods of using such polypeptides and polypeptide complexes.

The present invention provides a new antibody against ECSA type Chikungunya virus, WA type Chikungunya virus, and Asian type Chikungunya virus or an antigen-binding fragment of the antibody. The antibody against Chikungunya virus or the antigen-binding fragment of the antibody of the present invention includes a heavy chain variable region or a heavy chain (1), (2), or (3) and a light chain variable region or a light chain (4).

Aspects of the disclosure relate to nucleic acid vaccines. The vaccines include one or more RNA polynucleotides having an open reading frame encoding one or more Chikungunya antigen(s), one or more Zika virus antigens, and one or more Dengue antigens. Methods for preparing and using such vaccines are also described.

Disclosed are antigen binding polypeptides and antigen binding polypeptide complexes (e.g., antibodies and antigen binding fragments thereof) having certain structural features. Also disclosed are polynucleotides and vectors encoding such polypeptides and polypeptide complexes; host cells; chimeric antigen receptors (CARs); immune cells; pharmaceutical compositions and kits containing such polypeptides and polypeptide complexes; and methods of using such polypeptides and polypeptide complexes.

The present disclosure is directed to antibodies binding to and neutralizing Zika virus and methods for use thereof.

Described herein are nucleic acids encoding single-domain antibodies that might serve as alternatives to conventional monoclonal antibodies for either the detection or treatment of Chikungunya Virus (CHIKV).

The present disclosure provides humanized antibodies, including antibodies comprising an ultralong CDR3 and uses thereof.

The present invention relates to a new pestivirus useful in the fields of veterinary virology and vaccines. Specifically, it relates to an isolated polynucleotide originating from pestivirus and a pestivirus, to vaccines and medical uses thereof, to chimeric virus comprising the polynucleotide and to expression vectors for heterologous expression of polypeptides.

The invention relates to methods for the preparation of a pharmaceutical-vesicle formulation comprising steps of: preparing and processing vesicle components and a pharmaceutical agent to entrap the pharmaceutical agent in the vesicle and form a pharmaceutical-vesicle formulation, wherein the pharmaceutical-vesicle formulation is reconstituted in a known quantity of the pharmaceutical agent dissolved in a pharmaceutically-acceptable carrier to provide a biphasic pharmaceutical-vesicle formulation. The invention also relates to the associated pharmaceutical-vesicle formulations, pharmaceutical kits and uses as a medicament, in particular for the prevention or treatment of infection by bacteria such as Burkholderia pseudomallei and Francisella tularensis, and viruses such as Venezuelan Equine Encephalitis Virus (VEEV).
