Scientists have discovered that breast cancer can disrupt the brain’s internal clock almost immediately after the onset of cancer, without anyone noticing. In mice, tumors flattened the natural daily rhythm of stress hormones, disrupting the feedback loop between the brain and body that regulates stress, sleep, and immunity. Remarkably, when the researchers restored the correct […]
Anxiety and Insomnia are Associated With a Sharp Decline in Important Immune Cells
Natural killer cells act as the immune system’s rapid response team, but stress caused by anxiety and insomnia can reduce their numbers without anyone noticing. One study found that both conditions were associated with significantly lower numbers of NK cells—particularly the circulating types responsible for destroying infected or abnormal cells. As anxiety severity increased, NK […]
Circadian Rhythm and Diabetes Risk: What is the Connection?
Like all living beings, human physiological processes are influenced by circadian rhythms. The disruption of our internal clocks due to increasingly unbalanced lifestyles is directly linked to the explosive increase in type 2 diabetes cases. By what mechanism? A team from the University of Geneva (UNIGE) and Geneva University Hospitals (HUG) in Switzerland has lifted […]
Good Sleep Stimulates the Immune System
Sleep is healthy – this general finding is supported by science. Previous studies had already shown that people who slept after vaccination had an immune response that was on average twice as strong as people who did not sleep the night after vaccination. However, the cell biological reasons for this had hardly been investigated until […]
The Potential Role of Autophagy Disorders in the Development of Pancreatic Cancer
Scientists funded by Cancer Research UK have discovered dementia-like behavior in pancreatic cells that are at risk of becoming cancerous. The findings provide clues that could help in the treatment and prevention of pancreatic cancer, a difficult-to-treat disease that is responsible for 6,900 deaths in the UK each year. Approximately 495,000 new cases are diagnosed […]
