Methods for identifying compounds that positively regulate connexin 43 hemichannels.

The present disclosure is directed to methods (e.g., in vitro methods) for detecting the presence of neutralizing antibodies to PTH or PTHrP analog in a sample. The in vitro method comprises the steps of obtaining a sample from a subject; contacting the sample with a cell; measuring cyclic adenosine monophosphate (cAMP) levels; and detecting the presence of neutralizing antibodies when cAMP levels are reduced relative to a negative control sample without neutralizing antibodies. An in vitro method of detecting the presence of neutralizing antibodies in a sample from a subject treated with Abaloparatide, is also provided. Further provided herein is a kit for carrying out the methods described herein comprising components required to carry out the obtaining, contacting, measuring and detecting steps and instructions for use.

The present disclosure provides compositions, methods, systems, and devices for polynucleotide processing and antigen screening. Polynucleotide processing may be useful for a variety of applications. Antigen screening may comprise the use of one or more engineered cells. Engineered cells may be useful for characterizing one or more analytes including, for example, a polypeptide antigen.

The present disclosure provides methods of assaying for antibody-dependent cell-mediated phagocytosis (ADCP). In some embodiments, the methods include monomerizing and labeling a protein, contacting the protein with a protein-specific antibody to form an antibody-protein complex, contacting the antibody-protein complex with a phagocytic cell to permit phagocytosis, and assessing the amount of internalized fluorescence.

Compositions and methods for the treatment of amyloid deposit diseases, e.g., hereditary cystatin C amyloid angiopathy and other neurodegenerative disorders, are disclosed.

The present disclosure provides compositions, methods, systems, and devices for polynucleotide processing and analyte characterization from a single cell. Such polynucleotide processing may be useful for a variety of applications. The compositions, methods, systems, and devices disclosed herein generally describe barcoded oligonucleotides, which can be bound to a bead, such as a gel bead, useful for characterizing one or more analytes including, for example, protein (e.g., cell surface or intracellular proteins) and chromatin (e.g., accessible chromatin).

The present invention relates to an in vitro method for predicting the proangiogenic activity of preparations of extracellular vesicles (EVs), preferably blood-derived EVs, wherein the method is based on the combined determination of the content of transforming growth factor beta (TGFβ) and microRNA-130a. Also disclosed is a method of manufacturing a preparation of extracellular vesicles (EVs) predicted to have strong proangiogenic activity and the EVs preparations thereof, which are effective for the therapeutic treatment of ischemic diseases, ischemic injuries and pathological conditions associated with risk of cardiovascular disease, or for use in wound healing.
