摘要:
The present invention provides compositions and methods for regulating the specificity and activity of immune effector cells for use in immunotherapy. In one embodiment, the invention provides a type of chimeric antigen receptor (CAR) wherein the CAR is termed a “NKR-CAR” which is a CAR design comprising a component of a receptor naturally found on natural killer (NK) cells. In one embodiment, the NK receptor includes but is not limited to a naturally occurring activating and inhibitory receptor of NK cells known as a killer cell immunoglobulin-like receptor (KIR).
摘要:
Provided are compositions and methods relating to regulatable chimeric antigen receptors (RCARs), natural killer cell receptor CARs (NKR-CARs), and regulatable NKR-CARs (RNKR-CARs), where the intracellular signaling or proliferation of the RCAR or RNKR-CAR can be controlled to optimize the use of an RCAR/NKR-CAR- or RNKR-CAR-expressing cell to provide an immune response. Cells can be engineered to express a RNKR-CAR or to express a RCAR and a NKR-CAR (e.g., inhibitory NKR-CAR). For example, a RCAR or RNKR-CAR can comprise a dimerization switch that, upon the presence of a dimerization molecule, can couple an intracellular signaling domain to an extracellular recognition element, e.g., an antigen binding domain, an inhibitory counter ligand binding domain, or costimulatory ECD domain. An RCAR or RNKR-CAR can be engineered to include an appropriate antigen binding domain that is specific to a desired antigen target and used in the treatment of a disease.

The invention provides fibronectin type III (Fn3)-based binding molecules that bind to a specific target antigen. The invention further provides bispecific Fn3-based binding molecules that bind to two or more targets simultaneously. The Fn3-based binding molecules of the invention can also be linked together to form multispecific Fn3-based binding molecules, and/or can be conjugated to a non-Fn3 moiety, such as, Human Serum Albumin (HSA), for improved half life and stability. The invention also provides methods for generating, screening and using Fn3-based binding molecules in a variety of therapeutic and diagnostic applications.

The invention provides compositions and methods for treating diseases associated with expression of CD123. The invention also relates to chimeric antigen receptor (CAR) specific to CD123, vectors encoding the same, and recombinant cells comprising the CD123 CAR. The invention also includes methods of administering a genetically modified cell expressing a CAR that comprises a CD123 binding domain.
摘要:
The invention pertains to a natural-variant combinatorial library of fibronectin Type 3 domain (Fn3) polypeptides useful in screening for the presence of one or more polypeptides having a selected binding or enzymatic activity. The library polypeptides include (a) regions A, AB, B, C, CD, D, E, EF, F, and G having wildtype amino acid sequences of a selected native fibronectin Type 3 polypeptide or polypeptides, and (b) loop regions AB, CD, and EF having selected lengths (Bottom Loops). The Fn3 may also have loop regions BC, DE, and FG having wildtype amino acid sequences, having selected lengths, or mutagenized amino acid sequences (Top Loops).
摘要:
The invention pertains to an isolated VH single domain antibody comprising a C-terminal modification, where the C-terminal modification comprises a deletion of at least one amino acid residue that eliminates the interaction of a pre-existing antibody with the single domain antibody without interfering with the binding of the single domain antibody with its target.
摘要:
The here described invention discloses a combination of a top and bottom loop binder library using the CD and the FG loops of a number of FnIII domains (FnIII) (e.g., FnIII7, FnIII10 and FnIII14) together with the surface exposed residues of the beta-sheet. The invention also pertains to a method of forming a library of FnIII domain polypeptides useful in screening for the presence of one or more polypeptides having a selected binding or enzymatic activity.

摘要:
A method is proposed which enables high-resolution raster images to be represented on lower-resolution displays. The method according to the invention selects support points in lines and columns of the original image, which have a smallest possible variation of their distances and approximate the set scaling at least in ranges. Consequently, rational scaling ratios can also be achieved in an advantageous manner. In order to represent fine details of the original image in the scaled image as well, the adjacent pixels of the support points are also incorporated into the calculation of the pixels that are output. Furthermore, a circuit for scaling a raster image in real time is proposed. Moreover, a film scanner having a scaling device in accordance with the method according to the invention is proposed.
