Described herein are engineered microbe-targeting or microbe-binding molecules, kits comprising the same and uses thereof. The microbe-targeting or microbe-binding molecules can comprise a microbe surface-binding domain linked to a portion of an Fc region. Further, the microbe-targeting molecules can be conjugated to substrate (e.g., a magnetic particle) to form a microbe-targeting substrate. Such microbe-targeting molecules and/or substrates and the kits comprising the same can be used in various applications, such as diagnosis and/or treatment of an infection caused by microbes. Moreover, the microbe-targeting molecules and/or substrates can be easily regenerated after use.

A nucleic acid construct and an immune cell, which harbor nucleic acids encoding a CAR and nucleic acids encoding at least one anti-inflammatory or immunosuppressant protein and methods of using the same in treatment or amelioration of inflammation or immune-mediated autoimmunity are described.

The present invention relates to methods for promoting T cells response. The inventors examined the expression and function of CLEC-1 in human DCs and demonstrated for the first time a cell-surface expression. They investigated its functional role following triggering on orchestration of T-cell responses. The inventors showed in vitro and in vivo with CLEC-1 deficient rats and rat CLEC-1 Fc fusion protein that disruption of CLEC-1 signalling enhances in vitro Th17 activation and in vivo enhances T cell priming and Th17 and Th1 activation. In particular, the present invention relates to CLEC-1 antagonists for promoting T cells response in a subject in need thereof.

Several embodiments disclosed herein relate to the compositions comprising engineered Natural Killer (NK) cells that express a chimeric receptor, the chimeric receptor imparting to the NK cells an enhanced ability to target specific cells, such as cancerous cells or those affected by an infectious disease. Several embodiments relate to NK cells that target cells expressing natural ligands of NKG2D, where the NK cells comprise transmembrane and/or signaling domains that lead to cytotoxic and/or cytolytic effects when the NK cells bind a target cell. Uses of NK cell compositions to treat diseases are also provided for in several embodiments.

Provided herein are inhibitory chimeric antigen receptor compositions and cells comprising such compositions. Also provided are methods of using inhibitory chimeric antigen receptors and cells.

A chimeric antigen receptor, containing a ligand binding domain, a transmembrane domain, a co-stimulatory domain, and an intracellular signaling domain, the co-stimulatory domain containing CD94 and/or LTβ intracellular regions. The present invention further relates to engineered immune cells containing such a chimeric antigen receptor, and uses thereof in the treatment of diseases, such as cancer, autoimmune diseases, and infections.

Interleukin (IL)-33 is a critical regulator of allergic airway inflammation in the lung and is released by stressed or damaged epithelial cells. Here, Applicants show that alveolar macrophages regulate epithelial alarmin expression via CLEC-2 (C-type Lectin-like Receptor-2), which binds to PDPN (podoplanin). Therefore, CLEC-2/PDPN interactions are critical for regulating type 2 immunity in the lung and modulating expression of the epithelial alarmin IL-33. Methods are disclosed for therapeutic and screening applications. Novel therapeutic targets in alveolar macrophages and epithelial cells are disclosed.

The present invention provides a composition and method for treating an allergic disease. The composition comprises a ligand for asialoglycoprotein receptor 1 (Asgr1). The allergic disease may be atopic dermatitis, allergic rhinitis, urticaria, allergic asthma, allergic conjunctivitis, allergic gastrointestinal inflammation, or anaphylactic shock. The allergic disease may be caused by house dust mites. The present invention also provides a method for determining if a test compound activates human Asgr1.

The present invention relates, in part, to chimeric protein complexes including an anti-Clec9A targeting moiety, a modified Fc domain, and a modified human IFNα and their use as therapeutic agents. The present invention further relates to pharmaceutical compositions comprising the chimeric protein complexes and their use in the treatment of various diseases.

Engineered natural killer cells with switchable chimeric antigen receptor, methods of manufacture, pharmaceutical compositions, and methods of use in treating cancer and viral infection.
