  • However, considerable numbers of resident and infiltrating mononuclear cells are also present in skeletal muscles. (wikipedia.org)
  • By comparison, the mononuclear cells in muscles are much smaller. (wikipedia.org)
  • Some of the mononuclear cells in muscles are endothelial cells (which are about 50-70 μm long, 10-30 μm wide and 0.1-10 μm thick), macrophages (21 μm in diameter) and neutrophils (12-15 μm in diameter). (wikipedia.org)
  • However, in terms of nuclei present in skeletal muscle, myocyte nuclei may be only half of the nuclei present, while nuclei from resident and infiltrating mononuclear cells make up the other half. (wikipedia.org)
  • Considerable research on skeletal muscle is focused on the muscle fiber cells, the myocytes, as discussed in detail in the first sections, below. (wikipedia.org)
  • However, recently, interest has also focused on the different types of mononuclear cells of skeletal muscle, as well as on the endocrine functions of muscle, described subsequently, below. (wikipedia.org)

  • This most likely occurs from defects in postreceptor insulin signal transduction at the level of insulin receptor substrate-1 and phosphoinositide (PI) 3-kinase ( 6 - 9 ) as well as defects in trafficking and/or function of GLUT4 ( 10 , 11 ), the major insulin-regulated GLUT isoform expressed in skeletal muscle ( 12 ).
