The invention provides neuregulin antagonists and methods of using the neuregulin antagonists in delaying the time to tumor recurrence or preventing resistance of cancer cells to treatment with a therapeutic agent.

The present invention relates to compositions and methods for preventing, treating or delaying various cardiovascular diseases or disorders in mammals, particularly in humans. More particularly, the present invention provides for compositions and methods for preventing, treating or delaying various cardiovascular diseases or disorders using, inter alia, a neuregulin protein, or a functional fragment thereof, or a nucleic acid encoding a neuregulin protein, or a functional fragment thereof, or an agent that enhances production and/or function of said neuregulin.

Aspects of the present disclosure relate generally to chimeric proteins and pharmaceutical compositions comprising such chimeric proteins, and methods for using such chimeric proteins for treating acute radiation syndrome in subjects in thereof.

The present invention generally relates to uses of glial cell line-derived growth factor (GDNF) in cutaneous wound healing and hair growth. Methods of effecting hair growth and/or wound healing which feature administration of GDNF, or a biologically active fragment thereof, to subjects, e.g., human subject, are disclosed herein. The invention relates also to formulations and kits for achieving the indicated pharmaceutical advantages.

The present invention relates to compositions and methods of GDNF fusion polypeptides, wherein the GDNF fusion polypeptides include an Fc domain, an albumin-binding peptide, a fibronectin domain, or a human serum albumin, joined to a GDNF variant either directly or by the way of a linker. The GDNF fusion polypeptides may used to treat metabolic diseases, such as obesity and Type-1 and Type-2 diabetes, and neurological diseases, such as Amyotrophic lateral sclerosis (ALS) and Parkinson's disease.

Provided are a nucleic acid construct for achieving modular loading of an engineered EVs functional protein and use of said construct. A modular design principle is adopted, specific modules are selected for combination, a mutant sequence is optimized and screened to obtain an improved nucleic acid construct, and finally, the engineered EVs modularly loaded with functional protein is converted and expressed. The product has the following advantages that: I) the modular loading of the engineered EVs functional protein is achieved; 2) the loading density and the loading efficiency of the protein inside and outside an EVs membrane are improved; and 3) a specific support sequence module is selected to avoid enzyme digestion. The construct is used to prepare the engineered EVs, so that the modular loading of the functional protein can be achieved, the loading efficiency is improved, and the construct has a wide clinical application value and market prospect.
