Chronic stress increases the incidence of psychiatric disorders including anxiety, depression, and posttraumatic stress disorder. Repeated Social Defeat (RSD) in mice recapitulates several key physiological, immune, and behavioral changes evident after chronic stress in humans. For instance, neurons in the prefrontal cortex, amygdala, and hippocampus are involved in the interpretation of and response to fear and threatful stimuli after RSD.

Background: Chronic pain following traumatic stress exposure (TSE) is common. Increasing evidence suggests inflammatory/immune mechanisms are induced by TSE, play a key role in the recovery process versus development of post-TSE chronic pain, and are sex specific. In this study, we tested the hypothesis that the inflammatory marker C-reactive protein (CRP) is associated with chronic pain after TSE in a sex-specific manner.

Interleukin-1 (IL-1) is a pro-inflammatory cytokine that exerts a wide range of neurological and immunological effects throughout the central nervous system (CNS) and is associated with the etiology of affective and cognitive disorders. The cognate receptor for IL-1, Interleukin-1 Receptor Type 1 (IL-1R1), is primarily expressed on non-neuronal cells (e.g.

Article Synopsis
  • - The study explored the use of wrist-wearable devices to track heart rate variability (HRV) as potential biomarkers for recovery from adverse neuropsychiatric effects following traumatic events, specifically in a socioeconomically disadvantaged group.
  • - Researchers monitored participants within 72 hours of a traumatic event and over a course of 6 months, validating HRV characteristics linked to various posttraumatic symptoms, such as pain, re-experiencing, and anxiety.
  • - The findings indicate that changes in HRV could effectively predict improvements or worsening in symptoms, suggesting that these wearable technologies could serve as useful screening tools for identifying posttraumatic stress in high-risk populations.

Purpose: Lung metastasis is responsible for most deaths caused by osteosarcoma. How malignant bone cells coerce the lung microenvironment to support metastatic growth remains unclear. We sought to identify metastasis-specific therapeutic vulnerabilities by delineating the cellular and molecular mechanisms essential to metastatic niche formation in the lung.
