Understanding of biochemical mechanisms enables faster research paths to targeted, effective therapies. Medical News Today notes progress in knowledge of mechanisms of a range of age-related neurodegenerative conditions: "Many of these diseases are characterised by accumulation, inside nerve cells, of clumps of toxic proteins. ... failure of the dynein system causes the degeneration in a form of motor neuron disease, and that it is also involved in other conditions such as Huntington's disease. [The study] also provided further evidence for the idea [that] a key factor in the severity of these diseases is the rate at which these toxic clumps of protein can be removed. Enhancing the degradation of these protein clumps has the potential to delay the onset of, or even reverse, this group of diseases."
