Potassium Channels, Neurodegeneration

Fight Aging!

Do you want to live a longer life in good health? Simple practices can make some difference, such as exercise or calorie restriction. But over the long haul all that really matters is progress in medicine: building new classes of therapy to repair and reverse the known root causes of aging. The sooner these treatments arrive, the more lives will be saved. Find out how to help »

(From ScienceDaily). Age-related neurodegenerative diseases are failure modes of an exceedingly complex machine - so it shouldn't be surprising to find that many different mechanisms contribute to the sad end result: "[The gene] KCNC3 forms a potassium channel, part of a biochemical mechanism that regulates the electrical impulses of bursting neurons. Although potassium channel mutations have previously been linked to episodic disorders such as seizures, this is the first time they have been identified as causative factors - and potentially therapeutic targets - in neurodegenerative diseases. ... This is the first time neurodegeneration has been directly linked to potassium channel mutations."
