According to the present invention, a mutant rhodocytin lacking platelet aggregation ability is provided. According to the present invention, a pharmaceutical composition including a mutant rhodocytin lacking platelet aggregation ability is provided. According to the present invention, there is provided a method for inhibiting platelet aggregation by a platelet aggregating substance, including administering a pharmaceutical composition including a mutant rhodocytin lacking platelet aggregation ability to a subject in need thereof.

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).

The present invention provides engineered platelets with chimeric platelet receptors (CPR) with a desired target specificity. Additionally, the engineered platelets may comprise cargo which may be released upon activation of the platelet. Additionally, the platelets may be generated in vitro from megakaryocytes engineered to generate non-thrombogenic platelets.

The present application provides agents that specifically inhibits the IGFBP7/CD93 signaling pathway, such as agents that specifically block the interaction between CD93 and IGFBF7, methods of using said agents and methods of identifying said agents.

The invention relates generally to polypeptides comprising a lectin domain, multimeric proteins comprising the polypeptides, and use of the polypeptides or multimeric proteins in the detection of a carbohydrate (e.g., a sialic acid containing carbohydrate or Siglec ligand) or the treatment of a Siglec-mediated disorder.

Provided are compositions for activating NK cells to stimulate an immune response for treating cancer and other disorders. In one embodiment, the invention provides a compound comprising an NK engaging domain that binds to CD 16; an NK activating domain operably linked to the NK engaging domain; and a targeting domain that selectively binds to a target cell and is operably linked to the NK activating domain and the NK engaging domain, wherein the targeting domain binds to CLEC12A.

Disclosed are biomarker panels for evaluating subjects at risk of sinusoidal obstruction syndrome (SOS) early after hematopoietic stem cell transplantation (HSCT). In particular, the present disclosure relates to the use of one or more of ST2, ANG2, L-Ficolin, HA, and VCAM1 for prognosing, diagnosing, and/or treating SOS.

Described herein are compositions and techniques related to generation and therapeutic application of artificial synapses. Artificial synapses are engineered extracellular vesicles, including exosomes, which incorporate sticky binders on their surface to anchor signaling domains against biological targets, such as receptors. These engineered additives can be organized in genetic vector constructs, expressed in mammalian cells, wherein the sticky binders attach to extracellular vesicles such as exosomes, thereby presenting their joined signaling domains which are rapidly taken up by recipient cells. Artificial synapses adopt the hallmark biophysical and biochemical features of extracellular vesicles, allowing for rapid deployment and scale-up. Importantly, this strategy can allow for kinetically favorable signal generation and signal propagation. This includes, for example, increasing density of agonist presentation to support receptor clustering—an onerous barrier for traditional receptor targeting strategies.

The present invention relates to lebecetin, a functional variant or fragment thereof, for use as neovascularization inhibitor, in particular in the treatment of neovascular diseases such as ocular diseases, cancers or inflammatory disorders with a neovascular component.
