Deficient Atp Release In The Brain Drives Depressive- And Anxiety-like Behaviors

In a new JNeurosci paper, Tian-Ming Gao and colleagues, from Southern Medical University, explored how adenosine triphosphate (ATP) signaling relates to slump and anxiety using antheral mice. ATP is simply a molecule that not only provides energy but also supports connection between neurons. The researchers focused on ATP signaling in a encephalon region implicated successful slump called nan hippocampus. 

Male mice that were more apt to acquire depressive- and anxiety-like symptoms following long-term stress had less ATP levels and reduced look of a protein involved successful ATP release (connexin 43). When nan research team genetically dampened or deleted connexin 43 in cells that merchandise ATP in different group of mice, this unsocial led to depressive- and anxiety-like behaviors and lowered ATP levels. Bridging nan findings together, successful distressed mice, restoring connexin 43 successful nan hippocampus brought ATP levels up to normal and improved behavioral outcomes. 

This is nan first nonstop grounds that deficient ATP merchandise successful [a region of the] hippocampus drives some depressive- and anxiety-like behaviors, revealing a shared molecular pathway [for these conditions]."

Gao also emphasizes that the findings linking connexin 43 to this system constituent to a potential treatment target for treating slump and anxiety when they hap astatine nan aforesaid time. Of note, nan researchers plan to measure some sexes successful early studies.
