Abstract:
Objective Recently, the role of TREK-1 in anti-depression and neuroprotection was demonstrated definitely.In this paper,a systematic review about the functional structure of TREK-1 as well as the underlying mechanisms which involved in depression resistance and nerve protection was made for purpose of providing new ideas for the treatment of clinical diseases.Methods The electronic search of Medline/PubMed,CNKI,CBM and Wanfang Data were performed to collect the introduction of TREK-1 and the studies of depression and nerve protection in which TREK-1 participated from inception of each database to October 2015 ,besides the relevant references of the included studies were also retrieved.Results 30 studies were included in this paper.14 studies were about the interpretation of TREK-1's structure, distribution and the regulatory factors, and the number of researches regarding the involvement of TREK-1 in anti-depression and neuroprotection was 13 and 7 respectively.Based on these studies,it was easily to conclude that inhibition or blocking of TREK-1 channels can produce obvious antidepressant effect, however, activation of TREK-1 channels will induce the dilation of local cerebral vascular and silence hyperactive neurons.Conclusion Some achievements about the antidepressant and neuroprotective effect of TREK-1 channels in vivo have been made gratifyingly,thus future research should focus on exploring the best TREK-lactivation ratio in different brain regions to gain the best balance between anti-depression and neuroprotection.
