Hypothesis Article The role of exercise and PGC1alpha in inflammation and chronic disease

Christoph Handschin1 & Bruce M. Spiegelman2

Top

Inadequate physical activity is linked to many chronic diseases. But the mechanisms that tie muscle activity to health are unclear. The transcriptional coactivator PGC1alpha has recently been shown to regulate several exercise-associated aspects of muscle function. We propose that this protein controls muscle plasticity, suppresses a broad inflammatory response and mediates the beneficial effects of exercise.
