Transglutaminase-2 Promotes Microglial Synaptic Phagocytosis and Ameliorates Epileptic Seizures by Inhibiting ABCA1 Ubiquitination.

Summary: Imagine your brain is a complex garden. Sometimes, there are too many overgrown weeds (extra nerve connections), which can cause electrical storms in the brain. We call these storms epilepsy or seizures. The brain has special "gardener" cells called microglia whose job is to pull these weeds and keep the garden healthy.

Recently, scientists discovered that a protein called TGM2 acts like a super-tool for these gardeners. When there is more TGM2 in the brain, the microglia gardeners work much better. They pull the right weeds and calm the brain down, leading to fewer and less severe seizures. TGM2 does this by protecting another helpful protein (ABCA1) from being destroyed. This exciting discovery could lead to brand-new treatments to help stop epilepsy!
