«While previous studies at McLean and elsewhere have focused on the behavioral symptoms produced by
such immune activation, this study goes deeper, going to the cellular level to show how the brain's neural circuits are affected.»

«A growing body of evidence suggests that
immune system
activation,

Without
such activation by recognition of infection, Janeway suggested that the adaptive

immune cells,
such as NK cells.
Certain conditions
such as Hashimoto's Hypothyroidism, other autoimmune diseases, stubborn acne and PCOS tend to do better off all grains and legumes because of their lectin content, which along with problematic proteins (i.e. gluten in many grains) causes significant inflammation and
immune activation for them.
The researchers divided the 220 children into two categories — those with mothers who reported a history of chronic
immune activation (caused by asthma and allergies) and those with mothers who reported a diagnosis of an autoimmune condition,
such as diabetes and thyroid problems.
The release of inflammatory cytokines, or intercellular signaling molecules
such as interleukin - 1 (IL - 1), interleukin - 2 (IL - 6), and tumor necrosis factor alpha (TNF - α) at the site of
immune activation causes other
immune cells migrating throughout the lymphatic vessels of the body to express more cell adhesion molecules (CAMs).
The amygdala is response to peripheral
immune activation, so systemic inflammation,
such as in the gut, stimulates activity in the amygdala.
The result of an imbalance in cortisol, otherwise termed Hypothalamic Pituitary Adrenal (HPA) Axis dysregulation is weight gain, fatigue and brain fog, inflammation and
immune system
activation, digestive issues, restlessness, impaired sleep, decreased cognitive function, and mental health conditions,
such as anxiety and depression.
