Summary: Hemorrhage is the leading cause of death in severe trauma injuries. Damage-associated molecular patterns (DAMPs) are released into the intercellular environment when organs or tissues experience prolonged hypoxia. The endothelium plays a significant role in both the release and effects of DAMPs, contributing to immune-inflammatory dysregulation and tissue suffering. This review focuses on the pathophysiological roles of DAMPs and explores emerging therapeutic interventions for severe trauma, aiming to calm the inflammatory response triggered by traumatic hemorrhagic shock.

Summary: HMGB1 is a protein that can be found in the nucleus and cytoplasm, and its biological roles depend on its cellular location and modifications. While its role in inflammation is well-established, its role in cardiovascular diseases is not well understood. This review discusses the latest research on the link between HMGB1 and cardiovascular complications, with a focus on inflammation.

Summary: Sepsis is a major public health concern, especially among trauma patients, and the pathogenesis of the disease is still not fully understood. Recent studies suggest that mitochondrial-derived damage-associated molecular patterns may play a key role in the development of SIRS/sepsis. Therefore, further research on the role of mitochondrial DAMPs in inflammatory responses and sepsis is needed.

Summary: High mobility group box 1 (HMGB1) functions both as a nonhistone nucleoprotein and an extracellular inflammatory cytokine. It is mainly located in the nucleus in the resting state and regulates key nuclear activities. After spinal cord injury, HMGB1 is expressed by neurons, microglia, and ependymal cells and released into the extracellular matrix and blood circulation, contributing to the pathophysiological process of spinal cord injury. HMGB1 can regulate microglia activation, exacerbate inflammation, and result in neuronal death. However, it has also been shown to benefit neuron survival, regeneration, and motor function recovery. This article reviews the timing of HMGB1 secretion and translocation, release mechanisms, and its role in spinal cord injury, and identifies challenges to be addressed.

Summary: Diet is a modifiable risk factor for cardiovascular diseases, but our understanding of the role of dietary compounds in determining our health is limited. The Foodome project has focused on mapping the chemical complexity of food and predicting its impact on human health, using a multidisciplinary approach. This research has the potential to inspire next-generation drug discovery and combinations.

Summary: Increasing evidence supports the role of neuroinflammation in psychiatric diseases such as major depressive disorder (MDD) and COVID-19-related neuropsychiatric symptoms, but the underlying mechanism and therapeutic strategy are not well understood. This study found that the expression of MyD88, an adaptor protein involved in toll-like receptor signaling, was increased in the medial prefrontal cortex after chronic social defeat stress or exposure to the SARS-CoV-2 spike protein. Inhibiting MyD88 signaling showed potential as a therapeutic strategy for stress-related mental disorders.
