Exercise Attenuates Neuroinflammation in Chronic Restraint Stress Induced Depression Model by Downregulating GDF15 Expression.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Exercise has been shown to alleviate depressive symptoms and enhance bodily functions. However, the precise mechanisms underlying its antidepressant effects remain incompletely understood. In this study, we observed that treadmill exercise may exert antidepressant effects in a chronic restraint stress (CRS) mouse model by modulating the proinflammatory Growth Differentiation Factor 15 (GDF15)-extracellular signal-regulated kinase (ERK) signaling pathway. Treadmill exercise improved cognitive behaviors in CRS mice and alleviated neuroinflammation, as evidenced by decreased expression of TNF-α, IL-1β, IL-6, and attenuated microglia activation. Intriguingly, we found that treadmill exercise inhibited the expression of GDF15, a biomarker associated with many immune disorders, which is increased following CRS. Mechanistically, treadmill exercise may attenuate neuroinflammation by suppressing GDF15-induced ERK activation. We thus identified a novel mechanism by which treadmill exercise attenuates depression. Modulation of the GDF15-ERK pathway may have therapeutic implications for depression.
