Stress-Induced Depression And Comorbidities: From Bench To Bedside
Major depression (MD) is a severe, life-threatening and widespread psychiatric disorder, which is predicted to soon become one of the major causes of
death worldwide. However, despite extensive investigations, the exact mechanisms that lead to MD have not been identified. In a Special Collection to
be published this week in the online, open-access peer-reviewed journal PLoS ONE, a series of research articles highlight some of the current advances
in biological psychiatry, neuroscience, and neuroendocrinology which are shedding light on the connection between stress and depression.
The Collection (of 11 research articles), entitled, "Stress-Induced Depression and Comorbidities: From Bench to Bedside," represents the output of
a group of international research institutions, who collaborated around the causal link between stress exposure and depression vulnerability.
Dr Alessandro Bartolomucci of the University of Parma co-authored one of the research articles (Bartolomucci et al. 2009) as well as an accompanying
Overview of the topic ("Stress and Depression: Preclinical Research and Clinical Implications").
"I suggested PLoS ONE to my colleagues because as a member of the journal’s Editorial Board I had the chance to see how excellent the publication
process of PLoS ONE is, as well as its impact on science and society," explained Dr Bartolomucci. "Few journals could guarantee top publication
quality, a rigorous peer review system, excellent media coverage, high scientific impact and a broad audience, all of which are particularly important
A second Overview article ("Conceptual Challenges of a Tentative Model of Stress-Induced Depression") was written by Professor Bernhard Baune of
James Cook University, Australia, the PLoS ONE Section Editor for Neuroscience and Psychiatry and the editor who provided editorial oversight for the
collection, as well as coordinating the peer review of the research articles.
"The papers for the collection submitted to PLoS ONE deserve timely publication as they are all reflecting forefront research in stress-induced
depression spanning from basic to clinical research," said Professor Baune. "The employed animal models represent state-of-the-art research, which
is promising for furthering the development of clinically relevant interventions in patients with stress-induced depression. All the papers are of
Within the collection, preclinical and clinical research papers present an the results of an integrated experimental effort, employing a variety of
methods and concepts from different disciplines such as biological psychiatry, neuroscience, and neuroendocrinology and emphasizing how the link
between stress and depression can be deeper than previously understood.
Overall, the studies presented in this PLoS ONE Special Collection propose an integrated effort indicating how to move in the direction of joint
studies. The clear message is that both preclinical and clinical research will be pivotal in clarifying the validity of stress-induced depression, in
improving predictors for treatment response, and in providing a better basis for genetic studies, as well as in stimulating new drug discovery
processes.

PLoS ONE is the first journal of primary research from all areas of science to employ a combination of peer review and post-publication rating and
commenting, to maximize the impact of every report it publishes. PLoS ONE is published by the Public Library of Science (PLoS), the open-access
publisher whose goal is to make the world’s scientific and medical literature a public resource.
