The present invention relates to compositions and methods for treating diseases, disorders or conditions associated with the expression of the glycosyl-phosphatidylinositol (GPI)-linked GDNF family protein -receptor 4 (GFR4).

Provided herein are compositions, kits, and methods for manufacturing cells for adoptive cell therapy comprising engineered immune cells that overexpress Glucose Transporter 5 (GLUTS).

An antibody or an antigen-binding fragment thereof capable of specifically recognizing IL-11. The antibody includes heavy chain variable region CDRs as shown in SEQ ID NOs: 4-6, light chain variable region CDRs as shown in SEQ ID NOs: 37-39, heavy chain framework regions as shown in SEQ ID NOs: 67-70, and light chain framework regions as shown in SEQ ID NOs: 71-74, respectively. The antibody has low immunogenicity and can specifically target and bind to IL-11, so as to block binding of IL-11 to an IL-11 receptor.

CAR Tregs and Tregs are provided which are both conversion-resistant and condition-resistant. The Treg cells are engineered such that they are deficient in or substantially devoid of a cell-surface marker or antigen.

The invention relates to an artificial T cell receptor, wherein an antigen binding domain of the artificial T cell receptor specifically binds a complement pathway protein, nucleic acids encoding such artificial T cell receptors and cells engineered to express such nucleic acids. The invention also relates to targeting polypeptides comprising an extracellular ligand binding domain and an intracellular domain comprising a transcription factor, and wherein the transcription factor is configured to be released upon binding of the ligand binding domain by a ligand. The invention also relates to cells engineered to express the artificial T cell receptor and the targeting polypeptide, particularly where expression of the artificial T cell receptor is operatively linked to binding of the ligand binding domain. The cells of the invention are useful in medicine, particularly in the treatment of inflammatory conditions.

Provided are a product and a method for treating thrombocytopenia. The product and the method can fundamentally solve the problem of thrombocytopenia from the perspective of an autoimmune mechanism.

The present invention features compositions and methods related to the isolation, culture and therapeutic use of CD31-expressing cells.

The present invention generally relates to chimeric receptors comprising an extracellular domain comprising a mutated Fc domain. The invention also relates to transduced immune cells expressing the chimeric receptors of the invention and/or nucleic acid molecules encoding the chimeric receptors of the present invention. Further provided are kits comprising such cells and/or nucleic acid molecules encoding the chimeric receptors, and antibodies capable of binding to the chimeric receptors.

Described herein are engineered antigen presenting cells that can be capable of modulating a target T-cell in a T-cell antigen specific manner. In some embodiments, the engineered APCs can include a modified antigen presentation pathway. Also described herein are methods of making and using the engineered antigen presenting cells.

The invention provides compositions and methods for suppressing autoimmune components of neurodegenerative diseases and thereby providing therapeutic effects to patients suffering from such diseases. Compositions and methods include immunosuppressive moieties such as regulatory T cells (Tregs) and proteins expressed by Tregs coupled to a chimeric antigen receptor or protein that specifically binds one or more glial cell markers. Therapeutically effective doses of said compounds for treating neurodegenerative diseases including progressive supranuclear palsy (PSP), Parkinson's disease (PD), Alzheimer's, Huntington's disease, amyotrophic lateral sclerosis (ALS), chronic traumatic encephalopathy (CTE), and prion diseases are disclosed.
