Binding of MAGP2 to microfibrils is regulated by proprotein convertase cleavage.

MAGP2 is a small extracellular protein with both tumor angiogenesis and cell signaling activity. MAGP2 was originally isolated biochemically from microfibril-rich connective tissue. The localization of MAGP2 to microfibrils has been confirmed by both immunohistochemistry and immunogold electron microscopy.

Changes in motoneuron excitability in hemiplegic subjects after passive exercise when using a robotic arm.

Objective: To test the hypothesis that motoneuron excitability in stroke subjects is influenced by peripheral sensory input through passive exercise to the hemiplegic upper extremity.

Design: Case-control prospective study.

Setting: Physical medicine and rehabilitation inpatient and outpatient clinic at a tertiary Veterans Affairs medical center.
