摘要:
The present invention relates to a novel library for the generation of muteins and to novel muteins derived from human lipocalin 2 (Lcn2, hNGAL) and related proteins that bind a given target with detectable affinity. The invention also relates to corresponding nucleic acid molecules encoding such a mutein and to a method for their generation. The invention further relates to a method for producing such a mutein. For example, such muteins may serve to bind and deplete pathological forms of natural biomolecules such as the amyloid beta peptide in Alzheimer's disease or may target the fibronectin extra-domain B, which is associated with tumor neovasculature.

摘要:
Described are specific-binding therapeutic and/or diagnostic proteins directed against Glypican-3 (GPC3), which proteins include muteins of a lipocalin protein, such as lipocalin 2 (Lcn2 or NGAL). The invention also relates to nucleic acid molecules encoding such proteins and to methods for generation and use of such proteins and nucleic acid molecules. Accordingly, the invention also is directed to pharmaceutical and/or diagnostic compositions comprising such lipocalin proteins, including uses of these proteins.

The present invention relates to novel, specific-binding therapeutic and/or diagnostic proteins directed against Cytotoxic T-Lymphocyte Antigen 4 (CTLA-4) also known as CD152, which proteins preferably are muteins of a lipocalin protein, more preferably of lipocalin 2 (Lcn2 or NGAL). The invention also relates to nucleic acid molecules encoding such proteins and to methods for generation and use of such proteins and nucleic acid molecules. Accordingly, the invention also is directed to pharmaceutical and/or diagnostic compositions comprising such lipocalin proteins, including uses of these proteins.
摘要:
The present invention relates to a compound with affinity for the cytotoxic T lymphocyte-associated antigen (CTLA-4), wherein the compound exhibits a synergistic mode of action in that the compound: (a) increases T cell priming or T cell expansion or the generation of memory T cells by blocking of CTLA-4, and (b) enhances effector T cell activity in tumor tissue or lymphoid tissue by blocking of CTLA-4. The compound of the invention can be a protein, a small organic molecule, a peptide, or a nucleic acid. The invention also relates to a mutein derived from a protein selected from the group consisting of human neutrophil gelatinase-associated lipocalin (hNGAL), rat α2-microglobulin-related protein (A2m) and mouse 24p3/uterocalin (24p3), said mutein having binding specificity for the cytotoxic T lymphocyte-associated antigen (CTLA-4), wherein said mutein: (a) comprises amino acid replacements at least one of the sequence position corresponding to sequence positions 33 to 54, 66 to 83, 94 to 106, and 123 to 136 of hNGAL, and (b) binds human CTLA-4 with a KD of 50 nM or less. The invention also relates to a pharmaceutical composition comprising such a compound or mutein as well as to various pharmaceutical uses of such a compound or mutein, for example, for the prevention and/or treatment of cancer, an auto-immune disease or an infectious disease.
