HTT and Huntington disease: Bains et al. (2022) reported that ellagic and vanillic acids suppressed such pathological processes as oxidative stress, neuroinflammation, and mitochondrial dysfunction in an in vivo HD model, and reduced neuronal damage via AChE and caspase-3 inhibition. On the other hand, Pérez-Arancibia and colleagues reported that Ugni molinae extract reduced Huntingtin protein aggregation and modulated the expression of autophagy-related proteins in an in vitro cell model (Pérez-Arancibia et al., 2021).
