Middle-aged and older adults with higher levels of cumulative physiological stress, as measured by 12 biomarkers, have a 5.16 times higher rate of developing type 1 diabetes and a 2.50 times higher...
Mechanism
Synthesis from 1 study
Long-term stress keeps the body's stress system turned on, which stops the body from turning off inflammation. This lets immune cells attack the pancreas and joints, causing type 1 diabetes and spondyloarthritis. People with certain genes are more likely to have this happen, and not moving enough...
Most probable mechanism
Long-term stress keeps the body's stress response system constantly active, which reduces the ability of anti-inflammatory signals to calm down immune cells. This allows inflammation to build up unchecked, and immune cells begin attacking the body's own tissues, such as the pancreas and joints, leading to type 1 diabetes and spondyloarthritis.
Persistent psychological and environmental stressors cause sustained activation of the hypothalamic-pituitary-adrenal axis and sympathetic nervous system
Sustained stress exposure leads to glucocorticoid receptor desensitization, impairing the body's ability to suppress inflammation
Loss of glucocorticoid-mediated suppression permits continuous production of pro-inflammatory cytokines such as IL-6 and TNF-alpha
Chronic inflammation and altered immune signaling promote expansion of pathogenic T-cell populations, including Th17 cells
In individuals with high genetic susceptibility, epigenetic changes in immune cells lower the threshold for self-reactive activation
Self-reactive immune cells infiltrate and destroy insulin-producing pancreatic beta cells and inflame spinal and joint tissues
Less supported by current evidence, but not ruled out
Low intake of omega-3 fatty acids reduces the production of molecules that actively stop inflammation and repair tissue, allowing inflammation to persist and damage organs like the pancreas and joints.
Reduced dietary intake or plasma levels of omega-3 fatty acids decrease incorporation into immune cell membranes
Lower omega-3 levels shift lipid metabolism toward production of pro-inflammatory eicosanoids instead of specialized pro-resolving mediators
Deficient production of resolvins and protectins prevents timely termination of inflammation in pancreatic islets and joint tissues
Lack of regular movement reduces signals from muscles that calm inflammation and weakens the body's ability to turn off the stress response, allowing immune cells to remain overactive and attack tissues.
Low physical activity fails to stimulate vagal nerve activity and sustain sympathetic nervous system suppression
Absence of exercise prevents skeletal muscle from releasing anti-inflammatory signaling molecules such as IL-10 and IL-1ra
Reduced myokine signaling and impaired HPA-axis feedback allow systemic inflammation to remain elevated
