| Outline of Final Research Achievements |
Skeletal muscle atrophy with fatty degeneration and infiltration is often caused by tendon rupture or nerve damage. Adipokines secreted from infiltrated adipocyte is known to contribute to chronic inflammation. We focused on Adiponectin, and evaluated its effect on chronic inflammation.
We added Adiponectin to the muscle-derived cells cultured under inflammatory circumstances. Adiponectin showed the anti-inflammatory effect in this experiment. In in vivo experiment, muscle atrophy and fatty infiltration were observed in both torn tendon group and nerve damage group. The inflammatory cytokine was stimulated in atrophied and degenerated muscle. Simultaneously, Adiponectin was down-regulated in the endmysium of the atrophied muscle. Our results suggest that, in the atrophied and fatty infiltrated muscle caused by trauma such as tendon rupture and nerve damage, inflammation delays and chronic adipose inflammation would aggravate the clinical outcome.
