Scientists just found that certain brain immune cells (microglia) can actually flip a switch and protect us from Alzheimer’s instead of making things worse. When these cells get close to those nasty amyloid-beta clumps, they go into superhero mode, slowing down the disease in mice. The hope? Future treatments could train our own cells to fight back. Wild how our brains might already have some built-in defense! #Health #BodyHealth #Alzheimers
