Notably, there were six L-CMD patients who showed muscular dystrophic change with multifocal inflammatory cell infiltration in the endomysium or in the perivascular region of the perimysium (patients No.
The myopathic lesions have been shown to include multiple rounded muscle fibers with internalized nuclei [2,4,22] coupled with a diffuse thickening of endomysium and perimysium and loose collagen-rice connective tissue separating muscle fibers [6,8,22].
The criteria used in the selection of muscle fibers to measure the CSA included an intact, distinct endomysium without significant signs of distortion or folding.
Light microscopy of a vastus lateralis biopsy demonstrated ovoid organisms either free in the endomysium, within the myofiber sarcoplasm, or within macrophages in myofibers (Figure 1).
Meat tenderness originates in structural and biochemical properties of skeletal muscle fibres, especially myofibrils and intermediate filaments, and of the intramuscular connective tissue, (the endomysium and perimysium), which are composed of collagen fibrils and fibers.
Collagen is a molecule in ECM that plays an important role in building the base membrane of the myofiber endomysium in skeletal muscles [21].
There are three tiny collections of CD4+ T cells and CD68+ macrophages in endomysium. Blood vessels and connective tissue appear normal.
Irisin is secreted mainly in skeletal muscle, especially in the perimysium, endomysium, and nuclear parts, albeit adipose tissue, pancreas, sebaceous glands, and cardiac muscle have been identified as secretory tissues.
NCGS is characterized by the absence of celiac specific antibodies (against tissue transglutaminase, endomysium, and/or deamidated gliadin peptide) and absence of classical enteropathy (Marsh 0-1) although an increased density of CD3+ intraepithelial lymphocytes can be observed in duodenal biopsies.
(2011) reported that decrease of muscle stiffness was caused by increasing the flexibility and movement of the aponeurosis and the connective tissue, e.g., endomysium, perimysium, and epimysium, instead of lengthening muscle fiber.
