Their study, done in mice, ties the same neuronal connections that trigger insomnia to stress-induced changes in the immune system, which weaken the body\u2019s defenses against a host of threats.<\/p>\n<p>The study, reported September 9, 2020, in the journal Science Advances, connects and explains two familiar problems, says CSHL Assistant Professor Jeremy Borniger. \u201cThis sort of stress-induced insomnia is well known among anybody that\u2019s tried to get to sleep with a looming deadline or something the next day,\u201d he says. \u201cAnd in the clinical world, it\u2019s been known for a long time that chronically stressed patients typically do worse on a variety of different treatments and across a variety of different diseases.\u201d<\/p>\n<p>Like many aspects of the body\u2019s stress response, these effects are thought to be driven by the stress hormone cortisol. Working in the Stanford lab of Luis de Lecea, where Borniger completed a postdoctoral fellowship prior to joining CSHL, the research team found a direct connection between stress-sensitive neurons in the brain that trigger cortisol\u2019s release and nearby neurons that promote insomnia.<\/p>\n<p>\u2026 The same connection, they found, also has a potent effect on the immune system. Stress significantly disrupts the abundance of certain immune cells in the blood, as well signaling pathways inside them, and the team was able to recreate these changes simply by stimulating the same neurons that link stress to insomnia.<\/p>\n<p>Understanding this circuitry opens the door to a deeper understanding of the consequences of stress, not just in healthy individuals but also in disease, Borniger says:<\/p>\n<p>\u201cI\u2019m really interested in how we can manipulate distinct circuits in the brain to control not just the immune system at baseline, but in disease states like inflammatory bowel disease or in cancer or in psoriasis\u2014things that are associated with systemic inflammation. Because if we can understand and manipulate the immune system using the natural circuitry in the body rather than using a drug that hits certain targets within the system, I think that would be much more effective in the long run, because it just co-opts the natural circuits in the body.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Scientists at Cold Spring Harbor Laboratory (CSHL) and Stanford University have pinpointed the circuit in the brain that is responsible for sleepless nights in times of stress\u2014and it turns out that circuit does more than make you toss and turn.
