Assoc Prof Phil Sheard
http://phsl.otago.ac.nz/peoplelab.php?lab=22
Sarcopenia, the age-related loss of muscle mass and strength that has profound implications for the elderly. He is specifically interested in the role of the motor nerve terminal because progressive withdrawal of the motor nerve from the muscle fibre seems to be a conspicuous feature of elderly muscle. He is currently examining age-related changes to the neuromuscular junction with a view to using this information to establish whether motor nerve withdrawal is a cause of muscle fibre death, or a consequence of it. Associate Professor Sheard uses electrophysiology, electron microscopy, confocal microscopy, fluorescence and transmitted light microscopy, histochemistry, immunohistochemistry, and anterograde and retrograde cell tracing techniques.
