The primed rats, she discovered, were dramatically over-expressing cytokines in response to the second hit (, 2011).
Or it may be unintentional or subtle, such as someone avoiding you because the person assumes you could be unstable, violent or dangerous due to your mental illness. Some of the harmful effects of stigma can include: Others' judgments almost always stem from a lack of understanding rather than information based on facts.
Learning to accept your condition and recognize what you need to do to treat it, seeking support, and helping educate others can make a big difference.
They also express cytokines, the signaling molecules that serve as messengers between cells and are a key component of the body's inflammatory response.
Cytokines are important for the development of basic brain structures from blood vessels to axons.
When the body reacts to stressors, two systems kick into gear.
The endocrine system produces stress hormones such as cortisol.Something as simple as good prenatal care—from flu shots to proper nutrition—may help to prevent the biological chain reactions that underlie many psychological problems.Scientists studying the developmental roots of mental illness have zeroed in on a likely suspect: the body's stress response.And the sympathetic nervous system churns out other stress-related hormones such as epinephrine and norepinephrine—the factors responsible for the heart-pounding, sweaty-palms sensation known as the fight-or-flight response.Yet stress physiology encompasses much more than just stress hormones, says Thaddeus Pace, Ph D, an assistant professor of psychiatry and behavioral sciences at Emory University School of Medicine. "A stressful event can have profound effects on the amount of activity that's going on in the inflammatory immune system," he says. It has also been linked to a variety of bodily ills, from diabetes and heart disease to depression and Alzheimer's disease.Childhood maltreatment, for example, increases the odds of developing depression or post-traumatic stress disorder in adulthood.Now, researchers are finally beginning to understand the biological processes that underlie these links—findings that could point to new directions in treatment for mental illness and behavior disorders, and may even suggest routes to prevention.They are also involved in regulating cognition and mood, Bilbo says.She explored the brain's immune cells by infecting infant rats with the bacterium four days after birth, a developmental period comparable to the third trimester of pregnancy in humans.The risk is three times greater in people whose mothers had the flu during pregnancy, for example, while maternal iron deficiency during pregnancy increases the offspring's risk of the disease fourfold. Schizophrenia isn't the only mental illness linked to prenatal events.Using data from a Dutch birth cohort, Brown found that people whose mothers were undernourished while pregnant had a significantly increased risk of major affective disorders, such as mania and depression, severe enough to require hospitalization (, 2000).
