Yale study solves mystery of how stress triggers inflammation

• by Rich Haridy

The research reveals a particular immune cell is released by fat cells when an organism faces systemic stress.

For several decades a link between stress and inflammatory disease has been clear, with many chronic diseases obviously triggered into flare-ups by acute periods of stress. However, underlying this clear observation has been an unexplained paradox; hormones released by the body in the face of stress, such as cortisol and adrenaline, confer distinctly immunosuppressive effects, yet stress somehow still seems to stimulate inflammation.

"In the clinic, we have all seen super-stressful events that make inflammatory disease worse, and that never made sense to us," explains corresponding author on the study, Andrew Wang.

The new study stemmed from a novel laboratory observation.
