Systems and methods for purification and concentration of autologous alpha-2 macroglobulin (A2M) from whole blood and or recombinant A2M are provided. Also provided are methods of treating wounds with A2M. Methods for utilizing A2M in combination with other treatments (e.g., platelets and other growth factors) are provided in addition to combinations with exogenous drugs or carriers. Also provided is a method of producing recombinant A2M wild type or variants thereof where the bait region was modified to enhance the inhibition characteristics of A2M and / or to prolong the half-life of the protein for treating wounds.

A system for the detection of ligands comprising at least one receptor and an amplification mechanism coupled to the receptor wherein an amplified signal is produced as a result of receptor binding a ligand. Examples of suitable amplification mechanisms include antibody-embedded liquid crystalline materials; use of alpha-2-macroglobulin to encage an enzyme, whereby the enzyme is separated from its substrate by an receptor; and a receptor engineered to inhibit the active of site of an enzyme only in the absence of a ligand. Also provided are methods for the automatic detection of ligands.

The invention relates to a method for the diagnosis of non-alcoholic steatohepatitis (NASH), for determining the activity, the stage, or the severity of NASH or for classifying a subject as a potential receiver or non receiver of a treatment of NASH using circulating miRNAs and other bood circulating markers of liver damage, e.g. alpha 2 macroglobulin, HbA1c, N-terminal pro-peptide of collagen type III, miR-34 and miR-200. It also relates to a kit for implementing the method of the invention, and the compounds for use in a method for the treatment of NASH, wherein the subject to be treated isidentified, evaluated or classified according to the method of the invention.

Systems and methods for purification and concentration of autologous alpha-2-macroglobulin (A2M) from whole blood are provided. Also provided are diagnostic methods for identifying sites in the synovial joints, spine, tendons or ligaments for treatment of pain, degeneration, or inflammation with autologous A2M. Methods for utilizing autologous A2M in combination with other autologous treatments (e.g. platelets and other growth factors) are provided in addition to combinations with exogenous drugs or carriers. Also provided is a method of producing recombinant A2M wild type or variants thereof where the bait region was modified to enhance the inhibition characteristics of A2M and / or to prolong the half life of the protein in joints and spine disc or epidural space.

A2M polypeptide compositions containing a non-natural bait region are disclosed. Methods of producing wild-type and variant A2M polypeptides and polynucleotides containing a non-natural bait region are also disclosed. The bait regions of the variant A2M polypeptides demonstrate enhanced protease inhibitory characteristics compared to wild-type A2M. Variant A2M polypeptides that demonstrate longer half-lives upon administration to an organism compared to wild-type A2M are disclosed. The A2M compositions are useful in treating a number of diseases and conditions including inflammation, chronic wounds, and diseases with a pathology associated with proteases.

An assay for testing a subject for diabetes or a predisposition to diabetes including analyzing a biological fluid from a subject for the presence of one or more proteins selected from the group consisting of Alpha 2 macroglobulin, Apolipoprotein AII, Immunoglobulin alpha heavy chain constant region, Immunoglobulin mu chain C region, Chain A of Human IgA1, Inter-alpha-trypsin inhibitor heavy chain H4 precursor, and Apolipoprotein B11; wherein detection of the protein is indicative of diabetes or a predisposition to diabetes in the subject.

Provided are methods for the detection and diagnosis of acute coronary syndrome or ACS. The methods are based on the discovery that abnormal levels of selected analytes in sample fluid, typically blood samples, of patients who are at risk are supportive of a diagnosis of ACS. At least two new biomarkers for ACS are thus disclosed, MMP-3 and SGOT. Altogether the concentrations of twelve analytes provide a sensitive and selective picture of the patient's condition, namely, whether the patient is suffering a heart attack. Other important biomarkers for ACS are described, including but not limited to IL-18, Factor VII, ICAM-1, Creatine Kinase-MB, MCP-1, Myoglobin, C Reactive Protein, von Willebrand Factor, TIMP-1, Ferritin, Glutathione S-Transferase, Prostate Specific Antigen (free), IL-3, Tissue Factor, alpha-Fetoprotein, Prostatic Acid Phosphatase, Stem Cell Factor, MIP-1-beta, Carcinoembryonic Antigen, IL-13, TNF-alpha, IgE, Fatty Acid Binding Protein, ENA-78, IL-1-beta, Brain-Derived Nerotrophic Factor, Apolipoprotein A1, Serum Amyloid P, Growth Hormone, Beta-2 microglobulin, Lipoprotein (a), MMP-9, Thyroid Stimulating hormone, alpha-2 Macroglobulin, Complement 3, IL-7, Leptin, and IL-6. Kits containing reagents to assist in the analysis of fluid samples are also described.
