Disclosed herein are methods of treating cancer in a patient, the method comprising identifying a patient who is resistant to treatment with an anti-HER2 therapy; and administering to the patient a drug delivery molecule, comprising a polypeptide molecule adapted to target and/or penetrate a type of cell; a nucleic acid molecule bound to the polypeptide sequence via electrostatic interactions; and a chemical agent non-covalently linked to the nucleic acid sequence. Also disclosed are methods of inducing apoptosis in an anti-HER2 therapy resistant HER2+ breast cancer cell, the method comprising contacting the anti-HER2 therapy resistant HER2+ breast cancer cell with the drug delivery molecule. Further disclosed herein are methods of treating cancer in a patient, the method comprising identifying a patient who is resistant to anti-HER2 therapy; and administering to the patient a therapeutically effective amount of a drug delivery molecule, comprising a polypeptide molecule adapted to target and/or penetrate a type of cell; and a sulfonated corrole molecule bound to the polypeptide sequence. Finally disclosed herein are methods of inducing apoptosis in an anti-HER2 therapy resistant HER2+ breast cancer cell, the method comprising contacting the anti-HER2 therapy resistant HER2+ breast cancer cell with a drug delivery molecule, comprising a polypeptide molecule adapted to target and/or penetrate a type of cell; and a sulfonated corrole molecule bound to the polypeptide sequence.

Disclosed are compositions related to synthetic PD-1 peptides, chimeric PD-1 peptides, anti-PD-1 antibodies and methods of treating cancers, autoimmune diseases, and Alzheimer's disease using said peptides or antibodies.

The present invention includes compositions and methods for modifying a T cell with a nucleic acid encoding a switch molecule comprising an extracellular domain comprising a membrane receptor or fragment thereof and an intracellular domain comprising a signaling receptor or fragment thereof. In one aspect, a method comprises introducing a nucleic acid encoding a switch molecule and a nucleic acid encoding a soluble fusion protein and/or a nucleic acid encoding a bispecific antibody into a population of cells comprising T cells, wherein the T cells transiently expresses the switch molecule and soluble fusion protein or bispecific antibody. In other aspect, compositions of T cells and methods of treating a disease or condition, such as cancer or an autoimmune disease, are also included.

In one aspect, bispecific proteins having the ability to specifically bind to both subdomain II of human HER2 and subdomain IV of human HER2 are provided. In another aspect, methods of treating a cancer or treating brain metastasis of a cancer using a bispecific protein that specifically binds to subdomain II and subdomain IV of human HER2 are provided.

In various embodiments methods of producing a cell population enriched for CLEC9A+ dendritic cells are provided where the methods involve culturing stem cells and/or progenitor cells in a cell culture comprising culture medium, a notch ligand, stem cell factor (SCF), FLT3 ligand (FLT3L); thrombopoietin (TPO); and IL-3 and/or GMCSF.

Disclosed herein is a method for treating a subject having, or at risk of having, a cancer, comprising administering to the subject a therapeutically effective amount of a tumor membrane vesicle (TMV) and a metformin. In some embodiments, the TMV comprises a B7-1 and/or IL-12 molecule anchored to a lipid membrane (e.g., by a GPI anchor). In some embodiments, the methods can further comprise administering an immune checkpoint inhibitor. The methods are useful for reducing tumor size and metastasis, and in improving anti-tumor immune responses.

The present invention relates to a pharmaceutical composition comprising a modified mRNA that is stabilised by sequence modifications and optimised for translation. The pharmaceutical composition according to the invention is particularly well suited for use as an inoculating agent, as well as a therapeutic agent for tissue regeneration. In addition, a process is described for determining sequence modifications that promote stabilisation and translational efficiency of modified mRNA of the invention.

Cell-based compositions and methods for targeting and treating human diseases, including cancers and infectious diseases, are provided, wherein exogenous intracellular sarcosine is used for improved delivery of the composition.

The present invention provides MEL-18, which is a biomarker for human epidermal growth factor receptor2 (HER2)-positive cancer and anti-HER2 therapy, and a use thereof. According to the present invention, MEL-18 is a prognostic factor or predictor for a response of subjects to an anti-HER2-targeted drug in HER2-POSITIVE cancer and may be used in companion diagnostics for HER2-targeted drugs in subjects with HER2-positive cancer. Therefore, HER2-positive cancer may be more effectively treated by overcoming resistance to HER2 therapeutic agents and enhancing therapeutic efficacy by determining whether ADAM10/17 inhibitors are administered or co-administered with HER2-targeted drugs.

Methods for generating immune responses using adenovirus vectors that allow multiple vaccinations with the same adenovirus vector and vaccinations in individuals with preexisting immunity to adenovirus are provided.
