SNCA and synucleinopathy: MTs may offer neuroprotection in alpha-synucleinopathies, however, further studies are needed to determine if the neuroprotective action is mediated via copper chelation or is associated with ROS scavenging, neuroinflammation or neurotrophic effects, if MT and alpha-synuclein interact directly or indirectly and if this is intra- or extracellular.
