This disclosure provides pharmaceutical compositions and purified or isolated naturally occurring exosome products that have therapeutic use for treating an unmet medical need. The exosome compositions contain an effective amount of exosomes isolated from a body fluid of a non-diseased subject. The compositions are useful in the treatment of a variety of fibrotic diseases.

Provided are therapeutic, diagnostic, and prognostic methods for disease, including diseases associated with fibrosis and cancer using agents that bind to, inhibit, and/or detect lysyl oxidase-like 2 (LOXL2), and agents, compositions, kits, assay systems, and devices for use with such methods.

The present disclosure provides methods of treating fibrosis or a fibrotic disease or condition in a subject in need thereof comprising administering to the subject a therapeutically effective amount of cenicriviroc or a salt or solvate thereof. The fibrosis or fibrotic disease may be liver fibrosis, renal fibrosis, non-cirrhotic hepatic fibrosis, associated with non-alcoholic steatohepatitis (NASH), non-alcoholic fatty liver disease (NAFLD), or emerging cirrhosis.

The present invention provides an antibody to a fibrosis-related molecule and medical application thereof. The antibody of the present invention is an antibody that binds to CHL1 protein and an antibody that neutralizes the binding of the CHL1 protein to a fibroblast.

Excessive deposition of extracellular matrix is a hallmark of Idiopathic pulmonary fibrosis (IPF), it is advantageous to target the cells and the mechanisms associated with this process. By targeting myofibroblasts (specialized contractile fibroblasts) that are key for the development of IPF with drugs conjugated with fibroblast activation protein (FAP), this technology helps minimize the production of extracellular matrix in the lungs and provides a new treatment option for patients diagnosed with IPF.

Provided is a monoclonal antibody specifically reactive with a C-terminal neo-epitope of PIIINP comprised in a C-terminal amino acid sequence CPTGXQNYSP-COOH (SEQ ID NO: 4) in which X is Gly or Pro, and where the monoclonal antibody does not recognize or bind an elongated version of the C-terminal amino acid sequence CPTGXQNYSPQZ-COOH (SEQ ID NO: 5), in which Z is absent or is one or more amino acids of the sequence of collagen type III. Also provided is a method of immunoassay for detecting in a biological sample the C-terminal neo-epitope of PIIINP generated by N-protease cleavage of intact type III procollagen, by contacting the sample with the monoclonal antibody, and determining the amount of binding of the antibody.

The application concerns means for determining the stage of hepatic tissue damage, in particular the hepatic fibrosis score of subjects infected with one or more hepatitis viruses. In particular, the means of the invention involve measuring the levels of expression of selected genes, said selected genes being: SPP1, and at least one gene from among A2M and VIM, and at least one gene from among IL8, CXCL10 and ENG, and optionally, at least one gene from among the list of the following sixteen genes: IL6ST, p14ARF, MMP9, ANGPT2, CXCL11, MMP2, MMP7, S100A4, TIMP1, CHI3L1, COL1A1, CXCL1, CXCL6, IHH, IRF9 and MMP1.

An exemplary embodiment of the present disclosure provides A method and system for forming a microscale cell-laden matrix using an aqueous two-phase system (“ATPS”) comprising a mixture of a first material and a second material having a phase boundary between the first and second materials. The method can comprise mixing an enzyme with the first material, mixing a protein with the second material, and mixing a suspension comprising cells with one of the first material or the second material, wherein the enzyme, protein, and suspension comprising cells generate the cell-laden matrix and wherein the first material comprises a first polymer comprising polyethylene glycol and the second material can be a second polymer selected from the group consisting of dextran, polyvinyl pyrrolidone, polyvinyl alcohol, or ficoll.

Provided herein are, inter alia, compositions and methods for identifying and using agents capable of inhibiting myofibroblast transition as well as methods for treating diseases associated with the same in a subject in need thereof.

The present invention relates to the field of medicine and in particular to the diagnostic and treatment of fibrosis. More particularly, the invention relates to CD146 and uses thereof as a biomarker in the diagnosis of fibrosis and as a therapeutic target in the treatment of fibrosis. The invention also relates to compositions and methods of detecting predisposition to, of diagnosing, prognosing and/or monitoring fibrosis in a subject. It further relates to CD146 inhibitors, and to compositions comprising a CD146 inhibitor, for use in prevention or treatment of fibrosis in a subject, as well as to compositions, kits and uses thereof in a diagnostic or therapeutic context.
