Calorie restriction reduces the production of Prostaglandin E2 (PGE2), a suppressive factor for T-cells, which contributes to enhanced immune function.

Reducing calories, especially by 30%, lowers PGE2, a compound that suppresses T-cells. This reduction helps your immune system work better.

GoodSupportsHIGH confidence
The decline in PGE2 production following CR in humans might partly contribute to the CR-induced enhancement of T-cell function as PGE2 has been shown to be a negative regulator of T cells.
