“…Kyriatzis et al review current findings on the involvement of the neurotensinergic system in stress response and the pathophysiology of stress-related disorders, with an emphasis on gene, mRNA, and protein alterations, behavioral and pharmacological studies and therapeutic implementations [ 7 ]. Providing insights from mass spectrometry and nuclear magnetic resonance metabolomic studies in rodent models, Papageorgiou et al investigate affected molecular pathways upon stress exposure and provide insightful information on stress-induced systemic changes in the brain and the periphery [ 8 ]. The review article by MacKay et al focuses on the role of the gut-immune-brain axis, the human microbiome and the therapeutic potential of pro and prebiotics in stress-related disorders [ 9 ].…”
