However, the presence of orexin receptors at the gastrointestinal smooth muscle level has been found. On these grounds, in the present study we evaluated whether orexin A also exerts direct muscular effects in the duodenal smooth muscle of the mouse in an attempt to explain the possible mechanism of action involved. The experimental results from mechanical and electrophysiological studies indicate that orexin A causes direct contractile responses in the isolated preparations and evokes changes in the ionic currents of the smooth muscle cells. Thus, orexin A, in addition to its neutrally mediated influences on gastrointestinal motility, exerts direct muscular effects on the mouse duodenum. This latter mechanism, from a physiological point of view, may act in a synergic manner to reinforce the neuronal signals.<\/jats:p>","DOI":"10.1113\/jphysiol.2011.214940","type":"journal-article","created":{"date-parts":[[2011,9,13]],"date-time":"2011-09-13T06:44:35Z","timestamp":1315896275000},"page":"5231-5246","source":"Crossref","is-referenced-by-count":21,"title":["Muscular
