Next spring marks the return of Michael J. Fox to the forum he knows bestacting. He will play a wheelchair-bound love interest in the acclaimed firefighter drama Rescue Me on FX. The 47-year-old actor was last seen on TV in Boston Legal in 2006. So wheres he been? Battling Parkinsons disease and stumping for help.
Fox was diagnosed in 1991. And in 1998 he had a successful thalamotomy, a brain operation designed to reduce Parkinsons symptoms, particularly certain tremors. But he still takes daily meds to control his symptoms, and these drugs are far from perfect. Parkinsons patients lose the ability to make the brain chemical dopamine, and the meds restore that abilitytemporarily. Experts say that new treatments are desperately needed.
What about stem cells? Back in 2006, Fox went to bat for political candidates supporting publicly funded research into embryonic stem cells, the ones taken from unwanted embryos in fertility clinics. One day these cells may help cure diseases like Parkinsons. The actors stance brought him ridicule from talk-show host Rush Limbaugh, who accused Fox of undermedicating so his symptoms would be noticeable on TV and help his cause. But the misguided criticism only energized him. The Michael J. Fox Foundation for Parkinsons Research has now poured $126 million into research on treatments and a cure.
Both the political squabbles and scientific research on stem cells are ongoing. Many experts say embryonic research should be pursued, even as nonembryonic research goes forward. A potentially huge advance occurred this summer: Led by an investigator at Howard Hughes Medical Institute in Maryland, scientists converted cells from people with diseases like Parkinsons into a set of new stem cells. In the future, these cells might be re-engineered to correct genetic errors and implanted for treatment.
Gene therapies and drug advancements are also in the pipeline. But Fox knows that defeating Parkinsons will require much more effort. “Im grateful for my meds,” he says. “But its a little frustrating that the best drug weve got has been around for 40 years.” He hopes that changes … soon.
