According to embodiments, at least one polypeptide comprising at least one antiviral single domain antibody and their methods of use in antiviral treatment are provided. More specifically, embodiments provide at least one polypeptide having at least one anti-viral single domain antibody (e.g. anti-Hepatitis B Virus) for targeting a guanine-rich region of the viral DNA, inhibiting transcription of the viral DNA.

Disclosed herein are antibodies or immunogenic fragments thereof that specifically bind to Epstein-Barr virus (EBV) glycoprotein 350 (gp350) or 220 or one or more epitopes of EBV gp350 and neutralize EBV infection. Also disclosed are immunogenic peptides comprising one or more gp350 epitopes, EBV antibody-small molecule conjugates and pharmaceutical compositions comprising the antibody or an immunogenic fragment thereof, one or more epitopes of EBV gp350, one or more immunogenic peptides, or the EBV antibody-small molecule conjugate. The antibodies, epitopes, immunogenic peptides, conjugates, and pharmaceutical compositions can be used to treat or prevent EBV infections and EBV-associated conditions and diseases.

The present invention concerns methods and compositions for treatment of HIV infection in a subject, utilizing a DNL® complex comprising at least one anti-HIV therapeutic agent, attached to an antibody, antibody fragment or PEG. In a preferred embodiment, the antibody or fragment binds to an antigen selected from gp120, gp41, CD4 and CCR5. In a more preferred embodiment the antibody is P4/D10 or 2G12, although other anti-HIV antibodies are known and may be utilized. In a most preferred embodiment, the anti-HIV therapeutic agent is a fusion inhibitor, such as T20, T61, T651, T1249, T2635, CP32M or T-1444, although other anti-HIV therapeutic agents are known and may be utilized. The DNL® complex may be administered alone or may be co-administered with one or more additional anti-HIV therapeutic agents.

The present invention provides a composite comprising a novel antibody and at least one selected from the group consisting of a solid phase support and a labeled substance. The antibody consists of the amino acid sequence represented by SEQ ID NO: 08, and is capable of binding to an intranuclear protein of an influenza virus type A. The influenza virus type A is at least one selected from the group consisting of H1N1, H2N2, H3N2, and H7N9. The antibody is bound to the at least one selected from the group consisting of a solid phase support. The present invention also provides a detection device and a detection method using the composite.

The invention relates to a pharmaceutical composition soluble in an aqueous solution, which is characterised in that it comprises sialoglycosphingolipids; polypeptides selected from the group comprising antibodies, fragments and variants of same; and at least one therapeutically active substance, forming a ternary micellar complex of sialoglycosphingolipid-therapeutically active substance-polypeptide in which the polypeptides are non-covalently associated with the micelles formed by the sialoglycosphingolipid and the therapeutically active substance.

The invention relates to cancer therapeutics, in particular, the system of making cancer cells more susceptible to effector cells by introduction of cellular therapy targets into the cancer cells.

Provided are methods for manufacturing a conjugate containing a phthalocyanine dye, including methods that include one or more steps of preparing or producing the conjugate, formulating the conjugate and packaging the conjugate. In some aspects, the manufacturing methods result in the generation of a stable conjugate. Also provided are stable phthalocyanine dye conjugates, compositions and articles of manufacture containing the stable conjugates, and methods for their administration to subjects for photoimmunotherapy. In some embodiments, the phthalocyanine dye conjugates are conjugated to a targeting molecule, such as an antibody, that targets the conjugate to a cell or pathogen, such as by binding to a cell surface protein.
