The present invention relates to immunotherapeutic approaches to treating haematological cancers. In particular the invention relates to a method for treating a haematological cancer by targeting the 5T4 antigen. As such, the invention provides a method for treating haematological cancers comprising administering to a subject a 5T4-targeting agent. The invention also provides a 5T4-specific chimeric antigen receptor (CAR) and uses thereof in treating cancers.

Disclosed are compositions and methods for targeted treatment of CD33-expressing cancers. In particular, chimeric antigen receptor (CAR) polypeptides are disclosed that can be used with adoptive cell transfer to target and kill CD33-expressing cancers. Also disclosed are immune effector cells, such as T cells or Natural Killer (NK) cells, that are engineered to express these CARs. Therefore, also disclosed are methods of providing an anti-tumor immunity in a subject with a CD33-expressing cancer that involves adoptive transfer of the disclosed immune effector cells engineered to express the disclosed CARs. Also disclosed are multivalent antibodies are disclosed that are able to engage T-cells to destroy CD33-expressing malignant cells.

The present invention relates to compounds effective for the modulation of members of the protein kinase C (PKC) enzymatic family, including but not limited to, protein kinase epsilon (PKCε) inhibitors, protein kinase beta II (PKCβII) inhibitors, protein kinase zeta (PKCζ) inhibitors, and protein kinase C delta (PKCδ) activators. The present disclosure also relates to the mitigation of reperfusion (R) injury following the restoration of blood flow to previously ischemic (I) tissue. The present disclosure additionally relates to conjugates of PKC modulator peptides and a transduction domain of Trans-Activator of Transcription (TAT), and lipidated adducts thereof. The present disclosure further relates to a method of improving the therapeutic efficacy and solubility of compounds and drugs via dual conjugation of TAT and lipid moieties such as, for example, myristoyl.

The present invention relates to peptides and compositions for use in improving transduction efficiency of viruses into target cells.

The present invention is related to a method for detecting and identifying protein-protein or protein-small molecule interactions using a bait and prey system. It is also related to bait and prey proteins, small molecules and constructs that are used for the methods described herein.

The invention provides highly potent and stable peptide mimetics of human DKK3b having numerous improved properties. The peptide mimetics of the invention are useful as therapeutics in the treatment of various diseases wherein inhibiting nuclear translocation of β-catenin is therapeutic, including, but not limited to, cancer/proliferative, metabolic, osteoporosis, neurological, immunological, endocrinologic, cardiovascular, hematologic, and inflammatory diseases.

Disclosed herein are conjugates including a fatty acid, a self-assembly domain, and a polypeptide, where the conjugates have phase transition behavior. Further disclosed are methods of using the conjugates to treat disease, methods of delivering an agent, and methods of preparing the conjugates.

The present disclosure provides compositions and methods relating to modified mini-nucleosome core proteins and/ or delivery of nucleic acids. In particular, the present disclosure includes, among other things, non-viral proteinaceous vehicles for delivery of nucleic acids. In various embodiments, non-viral proteinaceous vehicles provided herein include (a) a nucleic acid binding domain; (b) a targeting domain; (c) a nucleic acid release domain; and, optionally, (d) further domains including, e.g., one or more of a stability domain, an oligomerization domain, and/or a linker domain. In various embodiments, the proteinaceous vehicles include one or more modified residues.

Chimeric antigen receptors for use in treating malignant melanoma and other cancers expressing CS1 are described.
