Structural and functional alterations in the neuromuscular system lead to physical disability and loss of independence in the elderly. Despite the importance of muscle strength in preventing physical disability, the cellular and molecular mechanisms responsible for the age-dependent decline in the neuromuscular system are only partially understood. The main focus of our research is to determine the molecular and cellular mechanisms underlying the age-dependent alterations in structure and function of motor neurons and skeletal muscle fibers.  Particularly, we are interested in the reciprocal interaction between muscle cells and brain and spinal cord motor neurons, the mutual influence of neurons and muscle cells on gene expression, the role of trophic factors and ion channels in tissue function, and interventions aimed at ameliorating and/or delaying the age-dependent impairment in the neuromuscular system.
