The main challenge is now to try and understand how this and the other PD-associated LRRK2 mutations lead to neurodegeneration and disease, in order to design novel therapeutic and preventive strategies.

...due to collapsing fisheries. "As we come to better understand the biology of these fish populations and what may have led to their dramatic decline, more and more people are realizing the role that selected reserves could play in addressing some of these problems," Hixon said.
