Phosphoglycerate dehydrogenase interacts with and inhibits the protein kinase TAK1 to mitigate septic shock.

Summary: Sepsis is a dangerous condition where the body's immune system overreacts to an infection, causing severe damage to organs. Scientists found that a special protein called PHGDH acts like a brake on this wild immune response. During sepsis, the body has less of this protein, which makes the inflammation worse. In tests on mice, adding more of this protein to lung cells helped calm the immune system and protect the organs. This exciting discovery shows that boosting PHGDH could be a promising new way to treat sepsis and save lives.
