INTRODUCTION Both target skeletal muscle (SKM) cells and neurotrophins (NTs) are essential for the maintenance of neuronal function and nerve-muscle communication. The effects of different NTs and SKM cells on growth-associated protein-43 (GAP-43) expression in dorsal root ganglion (DRG) neurons have not been clarified. METHODS The morphological(More)
BACKGROUND Intraluminal acid evokes sustained oesophageal longitudinal smooth muscle (LSM) contraction and oesophageal shortening, which may play a role in oesophageal pain and the aetiology of hiatus hernia. In the opossum model, this reflex has been shown to involve mast cell activation and release of neurokinins from capsaicin-sensitive neurons. The aim(More)
