Provided are NK-92 cells expressing a chimeric antigen receptor (CAR). The CAR can comprise an intracellular domain of FcεRIγ. Also described are methods for treating a patient having or suspected of having a disease that is treatable with NK-92 cells, such as cancer or a viral infection, comprising administering to the patient NK-92-CAR cells.

Disclosed herein include methods, compositions, and kits suitable for use in vaccination. There are provided, in some embodiments, nucleic acid compositions (e.g., mRNA vaccine, DNA vaccine) comprising a polynucleotide encoding a fusion protein. The fusion protein can comprise an antigenic polypeptide (AP) and an endosomal sorting complex required for transport (ESCRT)-recruiting domain (ERD). A plurality of fusion proteins can be capable of self-assembling into an enveloped nanoparticle (ENP) secreted from a cell in which the fusion proteins are expressed. There are provided, in some embodiments, populations of ENPs.

Provided are NK-92 cells expressing a chimeric antigen receptor (CAR). The CAR can comprise an intracellular domain of FcϵRIγ. Also described are methods for treating a patient having or suspected of having a disease that is treatable with NK-92 cells, such as cancer or a viral infection, comprising administering to the patient NK-92-CAR cells.

The present disclosure relates to compositions and methods for using cells having chemically-induced fusion protein complexes to spatially and temporally control immune cell signal initiation and downstream responses for treating disease. As a preferred example, the present disclosure relates to fusion polypeptides comprising (a) a first polypeptide comprising a first secretion signal, a first multimerization domain, a first transmembrane domain, and an actuator domain, (b) a viral self-cleaving polypeptide, and (c) a second polypeptide comprising a second secretion signal, a binding domain that comprises a single chain antibody, a receptor ectodomain, or a ligand, a second multimerization domain, and a second transmembrane domain.

The present invention relates to engineered extra-cellular vesicle internalizing receptors that have the ability to enhance uptake, processing, and presentation to T-cells of tumor-associated antigens by an antigen-presenting cell. It further relates to vectors or antigen presenting cells expressing said receptors, composition and uses thereof for the prevention and/or treatment of a cancer.

Genetically modified mice and methods and compositions for making and using the same are provided, wherein the genetic modification comprises humanization of an FcγRI protein.

The present invention discloses chimeric antigen receptors that specifically recognize and bind to SLe A carbohydrate antigen with high specificity and selectivity. The invention further provides lymphocytic cells, such as T cells, comprising said CARs, compositions comprising said cells or CARs as well as uses thereof.

Provided herein are recombinant nucleic acids encoding T cell receptor (TCR) fusion proteins (TFPs), modified human immune cells expressing the encoded molecules, and methods of use thereof for the treatment of diseases, including cancer.

The present invention relates to a chimeric antigen receptor comprising a c-Met binding domain, and a use thereof. The chimeric antigen receptor comprising a c-Met domain, of the present invention, can be effectively usable as an agent for treating various diseases associated with c-Met expression.

Disclosed are compositions and methods for treating disease or condition caused or exacerbated by S100A9 activity, such as myelodysplastic syndromes (MDS) using a composition comprising an effective amount of a CD33/S100A9 inhibitor.
