      Maintenance of endoplasmic reticulum (ER) proteostasis is controlled by a signalling network known as the unfolded protein response (UPR). Here, we identified filamin A as a major binding partner of the ER stress transducer ...
    • IRE1 signaling exacerbates Alzheimer's disease pathogenesis 
      Durán Aniotz, Claudia; Cornejo, Victor Hugo; Espinoza, Sandra; Ardiles, Alvaro O.; Medinas Bilches, Danilo; Salazar, Claudia; Foley, Andrew; Gajardo, Ivana; Thielen, Peter; Iwawaki, Takao; Scheper, Wiep; Soto, Claudio; Palacios, Adrian G.; Hoozemans, Jeroen J. M.; Hetz Flores, Claudio (Springer, 2017)
      Altered proteostasis is a salient feature of Alzheimer's disease (AD), highlighting the occurrence of endoplasmic reticulum (ER) stress and abnormal protein aggregation. ER stress triggers the activation of the unfolded ...
