Compounds, compositions, and delivery devices, for treating and diagnosing conditions and diseases associated with activation of the gonadotropin releasing hormone receptor (GnRHR), particularly those involving GnRHR activating autoantibodies (GnRHR AAbs). In one non-limiting embodiment, the disease is Polycystic Ovary Syndrome (PCOS). The therapeutic compounds in at least certain non-limiting embodiments include peptides which comprise D-amino acids (D-amino acid peptides) which are able to bind with high affinity to GnRHR AAbs.

A nanoparticle comprising an outer surface comprising a plasma membrane derived from a cell that can be infected with a respiratory virus, including a human lung epithelial cell expressing ACE-2 receptor. Methods of manufacture and use for preventing or treating viral infections, such as coronavirus infection in a subject in need are disclosed.

Nucleic acids comprising sequences that encode antibodies to human pituitary adenylate cyclase-activating peptide for the manufacture of antibodies to human pituitary adenylate cyclase-activating peptide.

This disclosure relates to a drug delivery system comprising an intraocular pressure lowering agent, a neurotrophic agent, such as a CNTF compound, a C-type Natriuretic Peptide (CNP) compound, a Tie-2 agonist, a Natriuretic Peptide Receptor-B (NPR-B) compound, or an apoptosis signaling fragment inhibitor (FAS) or FAS-ligand (FASL) inhibitor, including any combination of these compounds and a sustained delivery component. Methods of treating a glaucoma or related conditions, medicaments, kits, uses and methods of manufacturing are also described.

The present invention discloses novel methods, uses thereof, and compositions for modulating immune responses and homeostasis in a lymph node (LN). Moreover, structural and molecular characteristics of LN-innervating sensory neurons are provided. The present invention also discloses the target cells for LN-innervating sensory neurons in LN and molecular profiles of these target cells. These molecular characteristics provide therapeutic targets for modulating immune response and immune homeostasis in LN in an animal or a human.

In certain aspects, the present invention provides methods for dosing a patient with an activin-ActRIIa antagonist and methods for managing patients treated with an activin-ActRIIa antagonist. In certain aspects, the methods involve measuring one or more hematologic parameters in a patient.

Provided are compositions and methods for prophylaxis and/or therapy of disorders that involve seizures. The compositions and methods relate to a recombinant adeno-associated virus (rAAV) comprising a I56i enhancer sequence, and a sequence encoding hM3Dq modified muscarinic receptor (Gq-DREADD). The method includes introducing the rAAV into interneurons of an individual such that Gq-DREADD is expressed in interneurons of the individual. The method can further comprise administering to the individual an agonist of the Gq-DREADD, such for reducing or preventing seizures.

The present invention provides compositions and methods for treating hyperglycemia, insulin resistance, and associated organ damage, including in some embodiments diabetes mellitus (type 1 or 2), metabolic syndrome, obesity, fatty liver diseases, or kidney disease. In various embodiments, the invention involves administering a regimen of larazotide (or a derivative of larazotide) to a subject. In various embodiments, the regimen reduces dysfunction of the gastrointestinal epithelial barrier, thereby improving glycemic control. In various embodiments, the regimen of larazotide improves the effectiveness of conventional pharmaceutical interventions for hyperglycemia or diabetes mellitus.

Methods of treating patients having inflammatory bowel disease (IBD) or primary sclerosing cholangitis (PSC) are provided herein.

The invention features polypeptides that include an extracellular ActRIIa variant. In some embodiments, a polypeptide of the invention includes an extracellular ActRIIa variant fused to an Fc domain monomer or moiety. The invention also features pharmaceutical compositions and methods of using the polypeptides to treat diseases and conditions involving bone damage, e.g., primary osteoporosis, secondary osteoporosis, osteopenia, osteopetrosis, fracture, bone cancer or cancer metastasis-related bone loss, Paget's disease, renal osteodystrophy, treatment-related bone loss, diet-related bone loss, bone loss associated with the treatment of obesity, low gravity-related bone loss, or immobility-related bone loss.
