Research

Inter-organ communication is emerging as a fundamental mechanism regulating whole-body physiology and homeostasis. Organs communicate using secreted molecules that enter circulation, translocate to target tissues, and then direct a variety of processes including immunity, behavior, neurogenesis, cardiovascular function, and cellular aging. Our lab has special interests in the “Muscle-Brain” axis, and promote translational applications to treated neurodegenerative diseases.

Infection and chronic disease activate a brain-muscle signaling axis that regulates muscle performance 

Infections and neurodegenerative diseases induce neuroinflammation, but affected individuals often show a number of non-neural symptoms including muscle pain and muscle fatigue. The molecular pathways by which neuroinflammation causes pathologies outside the central nervous system (CNS) are poorly understood, so we developed three models to investigate the impact of neuroinflammation on muscle performance. We found that infectious and chronic diseases promoted the accumulation of reactive oxygen species (ROS) in the brain. Excessive ROS induces the expression of the cytokine Unpaired 3 (Upd3) in insects, or its orthologue IL-6 in mammals, and CNS-derived Upd3/IL-6 activates the JAK/Stat pathway in skeletal muscle. In response to JAK/Stat signaling, mitochondrial function is impaired and muscle performance is reduced. Our work uncovers a brain-muscle signaling axis in which infections and chronic diseases induce cytokine-dependent changes in muscle performance, suggesting IL-6 could be a therapeutic target to treat muscle weakness caused by neuroinflammation.
