Esto sugiere que atacar al daño que hacen las defensas del propio cerebro es otra vía posible, distinta de limpiar la proteína. Para los argentinos que tienen familiares con Alzheimer, es una señal de que hay caminos nuevos en investigación. Todavía falta mucho: lo probado es en animales y de un modelo a un humano hay un trecho largo.","quienFirma":"ScienceDaily","confianza":"divulgacion","consulta":null},"sello":{"hash":"c3add3dd0df78d1a8ee292660e3e1b39b1902c69d834930bb61dbfeeecf12b81","sello":"c6ae1367fc45bb4fe9c31cf407f3ca31dc39ff9225ca09dedc5aab836a529d22","beacon":{"drand":{"cadena":"8990e7a9aaed2ffed73dbd7092123d6f289930540d7651336225dc172e51b2ce","ronda":6569018,"aleatorio":"2403864da51bdd2a519360fd93e59fb5116563c5aaa8cd0a09e11cda13caaf48","tiempo":"2026-10-20T13:06:00.000Z"},"nist":{"cadena":2,"pulso":1991714,"salida":"B8848CECEB3DFDADAC825F4BEBDFF32AE2943FF3A9313DFB4B26C523DFDC5167BEA36151B2E895AB6BBE00295D1F2C46621B7595D8FD52F7309278148B7850D5","tiempo":"2026-10-20T13:05:00.000Z"},"noAntes":"2026-10-20T13:06:00.000Z"},"verificacion":{"drand":true,"nist":true},"tsa":{"time":"Oct 20 13:06:24 2026 GMT","provider":"freetsa.org","sobre":"sello"},"original":{"titulo":"Scientists find a way to fight Alzheimer’s brain damage without removing toxic tau","descripcion":"Scientists have found a promising way to protect the brain from Alzheimer’s-related damage by blocking immune cells that contribute to the destruction of neurons.
