Abstract
Life stressors can wreak havoc on our health, contributing to mood disorders like major depressive disorder (MDD), a widespread and debilitating condition. Unfortunately, current treatments and diagnostic strategies fall short of addressing these disorders, highlighting the need for new approaches. In this regard, the relationship between MDD, brain inflammation (neuroinflammation), and systemic inflammation in the body may offer novel insights. Recent research has uncovered the crucial role of astrocytes in coordinating the inflammatory response through the release of extracellular vesicles (ADEVs) during different neuroinflammatory conditions. While the contribution of ADEVs to stress and MDD remains largely unexplored, their potential to modulate immune cells and contribute to MDD pathogenesis is significant. In this article, we delve into the immunomodulatory role of ADEVs, their potential impact on peripheral immune cells, and how their microRNA (miRNA) landscape may hold the key to controlling immune cell activity. Together, these mechanisms may constitute an opportunity to develop novel therapeutic pharmacological approaches to tackle mood disorders.

Abstract
Clinical depression and anxiety are not just national health issues. They are significant global health problems, with a worldwide prevalence of clinical depression amounting to nearly 4%. Moreover, its prevalence is certainly underreported, particularly since the beginning of the COVID19 pandemic. This suggests that at least 26 million people are sad, fatigued, do not enjoy life, struggle with weight changes and experience suicidal thoughts. This Special Issue provides cutting-edge, new information from laboratories around the world about inflammation and depression. It consists of four review articles and five original research articles.
