BDNF and Huntington disease: This study aims to elucidate the potential neuroprotective effect of Candesartan (Cand) an AT1R blocker in mitigating neuronal degeneration caused by 3-Nitropropionic acid (3NP) induced HD by revealing the prospective role of Ang II/AT2R/Ang-(1-7)/Mas receptor, CREB/BDNF/PGC1-α besides JNK/c-Jun trajectories, as well as the anti-apoptotic survivin.
