This invention concerns anti-inflammatory agents, compositions, and methods for treating inflammatory disorders.

Provided are a fusion protein including glutathione-S-transferase and a protein having binding affinity for a target cell or a target protein, and use thereof as a drug delivery carrier and a pharmaceutical composition. The fusion protein and the drug delivery carrier including the same according to an aspect may sustain an in vivo residence time, and may also have improved target cell-targeting ability, and thus may be effectively delivered to target cells. Accordingly, it may be usefully applied to a targeted therapeutic agent.

Disclosed is an antibody in which the 80th amino acid residue in a variable region based on the Kabat method and the 171th amino acid residue in a constant region based on the Kabat method are substituted with cysteine in an antibody in which the 80th amino acid residue in the variable region and the 171th amino acid residue in the constant region are not cysteine.

IVIG replacement compounds are derived from recombinant and/or biochemical creation of immunologically active biomimetic(s). These replacement compounds are then screened in vitro to assess each replacement compound's efficiency at modulating immune function. Particular replacement compounds are selected for further in vivo validation and dosage/administration optimization. Finally, the replacement compounds are used to treat a wide range of diseases, including inflammatory and autoimmune diseases.

Blood-brain barrier permeable peptide compositions that contain variable antigen binding domains from camelid and/or shark heavy-chain only single-domain antibodies are described. The variable antigen binding domains of the peptide compositions bind to therapeutic and diagnostic biomarkers in the central nervous system, such as the amyloid-beta peptide biomarker for Alzheimer's disease. The peptide compositions contain constant domains from human IgG, camelid IgG, and/or shark IgNAR. The peptide compositions include heavy-chain only single-domain antibodies and compositions with one or more variable antigen binding domain bound to one or more constant domains.

The present disclosure is directed to a modified isolated immunoglobulin CH2 domain that specifically binds to an extracellular region of an EphA2 receptor, wherein the amino acid sequence of the modified immunoglobulin CH2 domain includes at least one amino acid substitution, addition or deletion in comparison to a wild type immunoglobulin CH2 domain amino acid sequence, wherein the wild type immunoglobulin CH2 domain amino acid sequence includes SEQ ID NO:1 or SEQ ID NO:2. Heterologous immunoconjugates including fusion proteins and pharmaceutical compositions including the modified isolated immunoglobulin CH2 domain are also disclosed. In addition, methods of treating a disease associated with EphA2 overexpression and methods for killing a target cell expressing EphA2 receptors using the modified isolated immunoglobulin CH2 domain are provided.
