Amyotrophic lateral sclerosis (ALS) is a fatal motoneuron disease with no current effective treatment. Accumulation of abnormal protein inclusions containing SOD1, TARDBP, FUS, among other proteins, pathological hallmark ALS. Autophagy the major degradation pathway involved in clearance damaged organelles and aggregates. Although autophagy has been shown to efficiently degrade ALS-linked mutant cell culture models, several studies suggest that impairment may also contribute pathogenesis. In this report, we tested potential use trehalose, disaccharide induces MTOR-independent autophagy, development experimental Administration trehalose SOD1 transgenic mice significantly prolonged life span attenuated progression signs.

Neurodegenerative diseases pose a substantial socioeconomic burden on society. Unfortunately, the aging world population and lack of effective cures foreshadow negative outlook. Although large amount research has been dedicated to elucidating pathologies neurodegenerative diseases, their principal causes remain elusive. Metal ion dyshomeostasis, proteopathy, oxidative stress, neurotransmitter deficiencies are pathological features shared across multiple disorders. In addition, these factors proposed be interrelated upon disease progression. Thus, development multifunctional compounds capable simultaneously interacting with several components suggested as solution undertake complex diseases. this review, we outline discuss possible therapeutic targets in Alzheimer's disease, Parkinson's amyotrophic lateral sclerosis molecules, previously designed or discovered potential drug candidates for disorders emphasis multifunctionality. underrepresented areas discussed indicate new directions.
