Muscle fibre expression of transforming growth factor-beta 1 and latent transforming growth factor-beta binding protein in canine masticatory muscle myositis.

Masticatory muscle myositis (MMM) is presumed to be an immunologically mediated canine myopathy but is of unknown origin. Severe atrophy and degeneration of masticatory muscle fibres, infiltration of eosinophilic granulocytes, and proliferation of the fibrous interstitial tissue are the hallmarks of MMM. Transforming growth factor-beta (TGF-beta) is a… CONTINUE READING
