The present invention provides compositions and methods related to equine live-attenuated influenza vaccines.

The present disclosure relates to a cluster-based consensus approach for generating recombinant hemagglutinin (HA) polypeptides. The disclosure further relates to influenza vaccine compositions comprising the recombinant HA polypeptides.

Systems and methods to genetically modify B cells to express selected antibodies are described. The systems and methods can be used to: obviate the need for classical vaccinations; provide protection against infectious agents for which no vaccinations are currently available; provide protection against infectious agents when patients are otherwise immune-suppressed; and/or provide a benefit provided by a therapeutic antibody, such as in the treatment of autoimmune disorders.

The present invention provides, among other things, methods, reagents, and systems for the treatment, detection, analysis, and/or characterization of influenza infections.

This invention relates to an adjuvant composition containing at least one binding molecule for neutralizing influenza virus and a vaccine composition containing the same. The composition containing at least one binding molecule for neutralizing influenza virus is capable of increasing the effects of a vaccine, and can thus be used as an adjuvant, which increases an immune response upon vaccine administration, and is very useful in the prevention of diseases caused by viruses.

Disclosed herein is a phage-displayed single-chain variable fragment (scFv) library, that comprised a plurality of phage-displayed scFvs characterized with (1) a specific CS combination; (2) a specific distribution of aromatic residues in each CDR; and (3) a specific sequence in each CDR. The present scFv library could be used to efficiently produce different antibodies with binding affinity to different antigens. Accordingly, the present disclosure provides a potential means to generate different antigen-specific antibodies promptly in accordance with the need in experimental researches and/or clinical applications.

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 relates in part to amino acid sequences that are directed against and/or that can specifically bind to an envelope protein of a virus, as well as to compounds or constructs, and in particular proteins and polypeptides, that comprise or essentially consist of one or more such amino acid sequences.

The present invention relates to hemagglutinin-specific antibodies, fragments thereof, and uses thereof. More specifically, these antibodies and fragments thereof are able to recognize antigen from multiple influenza strains.

The present disclosure relates to compositions and methods for treating or preventing a disease or disorder of the brain, spinal cord or central nervous system. It is described herein that an immunogenic composition which induces a CD4 T cell immune response induces permeability of the blood brain barrier, and allows for the access of a therapeutic antibody or agent to the brain, spinal cord or central nervous system.
