Abstract: The present invention relates to the field of GPCR structure biology and signaling. In particular, the present invention relates to protein binding domains directed against or capable of specifically binding to a functional conformational state of a G-protein-coupled receptor (GPCR). More specifically, the present invention provides protein binding domains that are capable of increasing the stability of a functional conformational state of a GPCR, in particular, increasing the stability of a GPCR in its active conformational state. The protein binding domains of the present invention can be used as a tool for the structural and functional characterization of G-protein-coupled receptors bound to various natural and synthetic ligands, as well as for screening and drug discovery efforts targeting GPCRs. Moreover, the invention also encompasses the diagnostic, prognostic and therapeutic usefulness of these protein binding domains for GPCR-related diseases.
Abstract: The present invention relates to a modified cytokine of the TNF superfamily, with reduced activity to its receptor, wherein said modified cytokine is specifically delivered to target cells. Preferably, said modified cytokine is a single chain variant of the TNF superfamily, even more preferably, one or more of the chains can-y one or more mutations, resulting in a low affinity to the receptor, wherein said mutant cytokine is specifically delivered to target cells. The targeting is realized by fusion of the modified cytokine of the TNF superfamily to a targeting moiety, preferably an antibody or antibody-like molecule. The invention relates further to the use of such targeted modified cytokine of the TNF superfamily to treat diseases.

Abstract: The compounds, compositions and methods provided herein antagonize, inhibit, decrease, reduce, suppress, or disrupt CD1d-mediated, iNKT cell-mediated, and/or iNKT cell TCR-mediated immune signaling. The sphingamide compounds were rationally designed based upon 3D structural considerations in relation to the structures of each of CD1d, the iNKT cell TCR, and the ternary complex CD1d-a-GalCer analog lipids-TCR. More specifically, the addition of an amide in the phytosphingosine tail of a derivative of ?-GalCer led to a non-conserved binding with CD1d, a conserved binding with the iNKT cell TCR, and an antagonist-like phenotype.

Abstract: Described are single domain antibodies with a specificity for BACE1. More specifically, described are single variable-domain antibodies derived from camelids that bind to BACE1 and are capable of inhibiting the activity of BACE1. The antibodies can be used for research and medical applications. Specific applications include the use of BACE1-specific antibodies for the treatment of Alzheimer's disease.
Abstract: The present invention relates to the field of disorders of the central nervous system, in particular neurological and psychiatric disorders, and the prevention and/or treatment thereof. In particular, the present invention relates to the finding that soluble amyloid precursor protein ? (sAPP?) presents a particular binding site, which allows for binding to the GABABR1a receptor, thereby causing an agonistic effect through specific binding to Sushi domain 1 of GABABR1a. As a result, the frequencies of excitatory and inhibitory postsynaptic currents are reduced. Accordingly, the invention provides compounds able to interfere with the association of sAPP? with Sushi domain 1 of GABABR1a and as such with selective impairment of GABABR1a beneficial in neurological and psychiatric disorders. The invention as well provides methods and (high content) screening assays for the production of said compounds.
Abstract: Methods for demannosylating phosphorylated N-glycans on a glycoprotein are described that use a mannosidase capable of hydrolyzing a terminal alpha-1,2 mannose linkage when the underlying mannose is phosphorylated.

Abstract: The present invention belongs to the field of functional proteomics and more particularly to the field of protein aggregation. The invention discloses a method for interfering with the function of a target protein and uses a non-naturally, user-designed molecule, designated as interferor, that has a specificity for a target protein and which induces aggregation upon contact with said target protein. The present invention also discloses such interferor molecules and their use in agrobiotech applications.
Abstract: The disclosure relates to a recombinant membrane span protein complex, comprising (1) a fusion protein, comprising a membrane span protein fused to a kinase domain, preferably a constitutive kinase and (2) a reporter construct comprising a polypeptide, interacting with the membrane span protein, fused to a reporter phosphorylation domain. The disclosure relates further to the uses of such membrane span protein complex for the detection of compounds that interact with the membrane span protein and for the screening and/or detection of inhibitors of the compound-membrane span protein interactions. In a preferred embodiment, the membrane span protein is a G protein coupled receptor (GPCR) and the method is used for the screening and/or detection of inhibitors of the ligand-receptor binding.
Abstract: The present application relates to the field of cancer, particularly to mismatch repair (MMR?) deficient tumors. New markers are presented herein that have a high sensitivity to detect whether a tumor is mismatch repair deficient or not. The markers are particularly mutations in microsatellite regions. Accordingly, methods are provided for diagnosing microsatellite instability of a tumor, comprising determining the presence of these markers. Further, kits are provided to detect the presence of these markers (or subsets thereof) in a sample.

Abstract: The present application relates to the field of glyco-engineering, more specifically to glyco-engineering of Fc-containing molecules, such as antibodies. It is shown herein that Fc-containing molecules with a specific glycosylation pattern have a considerably longer circulating half-life in vivo, without having an altered binding affinity for their respective antigen. This has therapeutic implications in reducing the frequency with which these molecules need to be administered, without affecting therapeutic efficacy. Also, cells are provided that can produce the Fc molecules with the desired glycosylation pattern.
Abstract: Described are nucleic acid regulatory elements that are able to enhance liver-specific expression of genes, methods employing these regulatory elements and uses of these elements. Expression cassettes and vectors containing these nucleic acid regulatory elements are also disclosed. These are particularly useful for applications using gene therapy.
