Methods for quantitative assessment of muscle fibers in muscular dystrophy

The disclosure concerns a method for assessing muscular dystrophy-linked protein expression in muscle fibers using digital image analysis of tissue. The method relates to assessing disease severity in individuals with muscular dystrophy. Muscle tissue samples are obtained from patients submitted for evaluation and processed to produce tissue sections mounted on glass slides which have been stained for a muscular dystrophy-linked protein. Digital images of the stained tissue sections are generated and analyzed by applying an algorithm process implemented by a computer to the images. The algorithm process extracts the morphometric and staining features of the muscular dystrophy-linked protein staining in the tissue, and parameters relating to these features are used to score the disease status for each patient submitted for evaluation. The score of disease status is ultimately used to infer disease severity, monitor the efficacy of a therapeutic approach, or select patients as candidates for a therapeutic approach.

Detecting inclusion body myositis

Methods, devices, kits and systems for diagnosing inclusion body myositis (IBM) are provided. Methods, devices, kits and systems involves detecting the presence and/or level of autoantibodies that are reactive against at least a ˜43 kilodalton (kDa) protein or ˜43 kDa protein band from a muscle lysate or a mammalian cell lysate, or autoantibodies that are reactive against a cytosolic 5′-nucleotidase 1A protein (NT5C1A), or a cytosolic 5′-nucleotidase 1B protein (NT5C1B), or a NT5C1B isoform thereof, or a peptide fragment thereof, an isolated peptide thereof or a fusion protein comprising an isolated peptide of NT5C1A or NT5C1B. Such autoantibodies are only found in IBM patients and not in patients with other myopathies.

PROTEIN ASSAY METHOD SPECIFIC TO TRACP-5b (TARTRATE RESISTANT ACID PHOSPHATASE 5b)

The purpose of the present invention is to provide a monoclonal antibody that is useful in specifically assaying tartrate resistant acid phosphatase 5b (TRACP-5b). A hybridoma producing a monoclonal antibody against TRACP-5b, said monoclonal antibody showing higher reactivity with TRACP-5b than with tartrate resistant acid phosphatase 5a (TRACP-5a) and, therefore, being specific to TRACP-5b, is obtained by cell fusion using, as an antigen, human recombinant TRACP-5b purified from silkworm silk gland. By using this monoclonal antibody, TRACP-5b in a specimen can be highly sensitively and specifically detected.

IDENTITY AND PURITY OF TISSUE BIOPSIES

A method for the in vitro detection of cartilage tissue and/or for the in vitro determination of the purity of cartilage tissue includes: a) treating a tissue sample with a protease and b) testing the protease-treated tissue sample for the presence of protease-resistant fragments of type II collagen and/or type I collagen. Methods can be carried out for preparing a cartilage cell culture, and for preparing a cartilage cell-loaded implant. Protease-resistant fragments of type II collagen and/or type I collagen can be used for the in vitro detection of cartilage tissue and/or for the in vitro determination of the purity of cartilage tissue. A kit can be used for carrying out the methods.
