The Claim
Chronic stress is associated with a shift in T-cell balance toward pro-inflammatory Th17 cells and away from regulatory T cells (Tregs), leading to increased IL-17 and decreased IL-10 production, which promotes loss of immune tolerance and autoimmunity in genetically predisposed individuals, as demonstrated in lupus-prone mice exposed to predator stress.
What the research says
Roughly balanced
Support and challenge are close. The picture may shift as more studies come in.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Long-term stress might throw your immune system out of balance, turning up inflammation and turning down protection, which could lead to autoimmune problems — especially in those who are already at risk — and this has been seen in mice prone to lupus when they're stressed by the smell of predators.

What the research says
1 studyStudy: Chronic Stress and Autoimmunity: The Role of HPA Axis and Cortisol Dysregulation
The study talks about how long-term stress can mess up your body's control systems and lead to immune problems, including autoimmune diseases like lupus. But it doesn't test the exact stress scenario or immune changes mentioned in the claim.
