Disclosed is a recombinant polypeptide for facilitating membrane fusion. The recombinant polypeptide having a sequence with at least 80% sequence identity with the ectodomain of p14 fusion-associated small transmembrane (FAST) protein and having a functional myristoylation motif, a transmembrane domain from a FAST protein and a sequence with at least 80% sequence identity with the endodomain of p15 FAST protein. A targeting ligand can be added to the recombinant polypeptide for selective fusion. The recombinant polypeptide can be included in the membrane of a liposome, or the like, to facilitate the delivery of bioactive compounds, such as siRNA, or the recombinant polypeptide can be mixed with a lipid carrier and added to cultured cells to induce cell-cell fusion and heterokaryon formation.

Provided herein are compositions and methods for adoptive cell therapy comprising engineered immune cells that express an antigen-targeted chimeric antigen receptor and a prodrug converting enzyme for the treatment of inflammation, inflammatory diseases, or pathogenic infections.

Disclosed are chimeric antigen receptors comprising a CD2 co-stimulatory domain that retain function against CD58.sup.− and CD58.sup.low tumor cells, and CD2 co-stimulatory receptors that promote CAR function against CD58.sup.− and CD58.sup.low tumor cells.

Non-human animal genomes, non-human animal cells, and non-human animals comprising a humanized TRKB locus and methods of making and using such non-human animal genomes, non-human animal cells, and non-human animals are provided. Non-human animal cells or non-human animals comprising a humanized TRKB locus express a human TRKB protein or a chimeric transthyretin protein, fragments of which are from human TRKB. Methods are provided for using such non-human animals comprising a humanized TRKB locus to assess in vivo efficacy of human-TRKB-targeting reagents such as nuclease agents designed to target human TRKB.

The invention relates to a compound comprising: CH.sub.2—CH.sub.2—F-Cha-Cha-RKPNDK-NH.sub.2 joined via a linking group to [Myr2]-KSSKSPSKKDDKKPGD. The invention also relates to its use in treatment of atheroma, use in treatment of atherosclerosis, use in inducing regression of atherosclerosis, and use in treatment of Acute Kidney Injury (AKI).

This invention is directed to chimeric antigen receptors and cells comprising the same, wherein the cells further secrete monoclonal antibodies locally at a tumor site.

The present invention provides multivalent CD20-binding molecules, and compositions thereof, such as enriched compositions comprising large proportions of multivalent CD20-binding molecule relative to monovalent CD20-binding molecule. Certain multivalent CD20-binding molecules of the present invention comprise 1) two or more CD20 binding regions and 2) one or more Shiga toxin effector polypeptide regions derived from an A Subunit of a member of the Shiga toxin family. Certain multivalent CD20-binding molecules of the present invention, and compositions thereof, have uses for selective killing specific cell types and as therapeutics for the treatment of a variety of diseases, including cancers, tumors, and immune disorders. Certain multivalent CD20-binding molecules of the present invention, and compositions thereof, have uses for delivering agents into CD20-expressing cells, including for the intracellular labeling of CD20-expressing cells, collecting diagnostic information, and monitoring the treatment of variety diseases, such as cancers, tumors, and immune disorders which involve CD20-expressing cells.

Disclosed herein is a recombinant protein including botulinum toxin and cell penetrating peptides and cosmetic composition. The cell penetrating peptide according to the present disclosure may be actively used as a topical agent for various disease treatment, aesthetic, or cosmetic purposes, especially for a cosmetic composition, by securing better convenience as well as maximizing the intrinsic in vivo efficacy of the botulinum toxin through the cell penetrating recombinant proteins that combines the botulinum toxin and a cell penetrating peptide by making skin penetration and/or cell penetration for botulinum toxin more efficient.

A chimeric antigen receptor (CAR) that binds to CEACAM6, an epitope or fragment thereof, or a variant thereof.

BCMA-specific fibronectin type III (FN3) domains, BCMA-targeting chimeric antigen receptors (CARs) comprising the FN3 domains, and engineered BCMA-targeting immune cells expressing the CARs are described. Also described are nucleic acids and expression vectors encoding the FN3 domains and the CARs, recombinant cells containing the vectors, and compositions comprising the engineered immune cells. Methods of making the FN3 domains, CARs, and engineered immune cells, and methods of using the engineered immune cells to treat diseases including cancer are also described.
