The present invention relates to CX3CR1-binding polypeptides, in particular polypeptides comprising specific immunoglobulin domains. The invention also relates to nucleic acids encoding such polypeptides; to methods for preparing such polypeptides; to host cells expressing or capable of expressing such polypeptides; to compositions comprising such polypeptides; and to uses of such polypeptides or such compositions, in particular for prophylactic, therapeutic and diagnostic purposes.

Described herein are single-domain antibodies that might serve as alternatives to conventional monoclonal antibodies for either the detection or treatment of Venezuelan equine encephalitis virus (VEEV).

The invention describes anti-cancer therapies comprising using an LRP5 antagonist in combination with an anti-PD1 antibody, each as described herein.

Methods of decreasing shedding of CD28, decreasing soluble CD28 levels, treating cancer and improving immunotherapies comprising inhibiting matrix metalloproteases are provided. Methods of producing agents for performance of the methods of the invention are also provided.

Provided are anti-TIGIT antibodies that bind to “T cell immunoreceptor with Ig and ITIM domains (TIGIT)”, including multispecific anti-TIGIT antibodies with binding specificity for TIGIT and one or more additional antigen, and methods of using the same. In certain embodiments, the anti-TIGIT antibodies comprises a single domain antibody that binds to TIGIT. In certain embodiments, the one or more additional antigen comprises Programmed cell death ligand 1 (PDL1).

The present invention relates to a binding polypeptide specifically binding to an epitope comprised in an amino acid sequence corresponding to amino acids 250 to 300 of the norovirus genotype II.10 capsid polypeptide, and to a polynucleotide encoding the same. The present invention further relates to a composition comprising the binding polypeptide according to the present invention and a carrier, and to the binding polypeptide or the composition comprising the same use in diagnosis and/or for use in medicine. Further more, the present invention relates to kits, devices, vaccines, methods, and uses related to the binding polypeptide of the present invention.

The invention relates to single domain VHH fragments which specifically bind to and inhibit superoxide dismutase and/or bind to and inhibit catalase and/or bind to and inhibit superoxide dismutase and catalase, in particular for the use in the therapy of tumor diseases.

Pharmaceutical compositions comprising antibody-urease conjugates and substantially free of unconjugated urease are disclosed. These compositions are prepared by a method that does not require chromatographic purification. These pharmaceutical compositions have utility in the treatment of cancer by antibody-directed enzyme prodrug therapy wherein the urease converts endogenous urea into ammonia in situ to induce cytotoxicity.

This invention provides, and in certain specific but non-limiting aspects relates to: assays that can be used to predict whether a given ISV will be subject to protein interference as described herein and/or give rise to an (aspecific) signal in such an assay (such as for example in an ADA immunoassay). Such predictive assays could for example be used to test whether a given ISV could have a tendency to give rise to such protein interference and/or such a signal; to select ISV's that are not or less prone to such protein interference or to giving such a signal; as an assay or test that can be used to test whether certain modification(s) to an ISV will (fully or partially) reduce its tendency to give rise to such interference or such a signal; and/or as an assay or test that can be used to guide modification or improvement of an ISV so as to reduce its tendency to give rise to such protein interference or signal; —methods for modifying and/or improving ISV's to as to remove or reduce their tendency to give rise to such protein interference or such a signal; —modifications that can be introduced into an ISV that remove or reduce its tendency to give rise to such protein interference or such a signal; ISV's that have been specifically selected (for example, using the assay(s) described herein) to have no or low(er)/reduced tendency to give rise to such protein interference or such a signal; modified and/or improved ISV's that have no or a low(er)/reduced tendency to give rise to such protein interference or such a signal.

There is provided inter alia a polypeptide comprising an immunoglobulin chain variable domain comprising three complementarity determining regions (CDR1-CDR3) and four framework regions, wherein: (a) at least one lysine residue in CDR1, CDR2 and/or CDR3 has been substituted with at least one histidine residue, and/or (b) at least one arginine residue in CDR1, CDR2 and/or CDR3 has been substituted with at least one histidine residue; wherein the polypeptide has increased intestinal stability relative to a corresponding polypeptide not having said histidine substitutions.
