A modular, small molecule regulated single chain variable fragment (scFv) fusion protein is disclosed. The scFv fusion protein comprises a ligand binding protein fused to a protein that binds to an exogenous control molecule, wherein the scFv fusion protein is directly regulated by the control molecule. Binding of the control molecule to the ligand binding protein induces a change in the affinity of the scFv for a target antigen. Methods of using the fusion protein to treat diseases such as cancer are also described.

Provided are methods for sensitizing gastrin-associated tumors and/or cancers in subjects to inducers of humoral and cellular immune responses. In some embodiments, the methods relate to administering compositions that have anti-gastrin antibodies, gastrin peptides, and/or nucleic acids that inhibit expression of gastrin gene products to subjects. Also provided are methods for preventing, reducing, and/or eliminating the formation of fibroses associated with tumors and/or cancers, and methods for treating gastrin-associated tumors and/or cancers that include administering to subjects in need thereof a first agent that provides and/or induces an anti-gastrin humoral or cellular immune response in the subject and a second agent that includes one or more stimulators of cellular immune responses against the tumors and/or cancers.

The compositions and methods described herein are directed to treating solid tumor using CAR T therapy. The compositions include CAR comprising an extracellular domain that binds a siglec protein or a receptor that binds the peptide hormone kisspeptin.

Provided herein are therapeutic methods of treatment using agonist leptin receptor (LEPR) antibodies, antigen-binding fragments thereof, or compositions comprising the LEPR antibodies or antigen-binding fragments thereof. Such therapeutic methods include treatment for conditions related to metabolic dysfunction, including for example, lipodystrophy, adiposity or obesity, reducing body weight, non-alcoholic fatty liver disease, hyperphagia, hyperglycemia, insulin resistance, dyslipidemia, hepatic steatosis, and infertility.

Provided herein are anti-Anti-Miillerian Hormone Receptor 2 (AMHR2) antibodies and methods of using such antibodies, for example, in the treatment of cancer.

The present invention is directed to antibodies and antigen binding fragments thereof having binding specificity for PACAP. The antibodies and antigen binding fragments thereof comprise the sequences of the V.sub.H, V.sub.L, and CDR polypeptides described herein, and the polynucleotides encoding them. Antibodies and antigen binding fragments described herein bind to and/or compete for binding to the same linear or conformational epitope(s) on human PACAP as an anti-PACAP antibody. The invention contemplates conjugates of anti-PACAP antibodies and binding fragments thereof conjugated to one or more functional or detectable moieties. Methods of making said anti-PACAP antibodies and antigen binding fragments thereof are also contemplated. Other embodiments of the invention contemplate using anti-PACAP antibodies, and binding fragments thereof, for the diagnosis, assessment, and treatment of diseases and disorders associated with PACAP and conditions where antagonism of PACAP-related activities, such as vasodilation, photophobia, mast cell degranulation, and/or neuronal activation, would be therapeutically beneficial.

Provided herein are novel polypeptides, methods for their production and uses thereof.

Various aspects of the present invention relate to a method of treating cancer in a subject having cancer cells, wherein the cancer cells possess at least one growth hormone receptor, and wherein the method includes controlling an action of the growth hormone receptor. In various non-limiting embodiments, controlling an action of the growth hormone receptor may occur via knock down of the growth hormone receptor, or may be caused by inhibiting growth hormone action, such as via the use of antibodies directed against growth hormone or the growth hormone receptor. Methods may also relate to administering an antagonist of the growth hormone receptor, and administering at least one anti-tumor drug in concert with administration of the antagonist. Another aspect may include a method of maintaining an anti-tumor drug in cancer cells of a subject by controlling an action of at least one growth hormone receptor in the cancer cells.

Aspects of the disclosure relate to chimeric antigen receptors (CARs) comprising an antigen binding domain (e.g., anti-TSHR), transmembrane domain (e.g., CD28), and a cytoplasmic domain (e.g., CD27, CD-137, etc.) and a safety mechanism comprising an inducible apoptosis trigger. In some aspects, the disclosure relates to use of the CARs in T cells, compositions, kits and methods for the treatment of thyroid cancers.

An invention relates to therapies for treating obesity, overweight and/or diabetes, in particular type 2 diabetes. The invention relates to a composition including at least one amylin receptor agonist, such as pramlintide, and at least one GLP-1 receptor agonist, such as exenatide or lixisenatide. The invention also relates to a composition for use in the method for the treatment of obesity, overweight and/or diabetes, in particular type 2 diabetes, wherein it reduces the slowing effect of gastric emptying of amylin RA as compared to the same composition without the corresponding GLP-1 RA.
