Eric Dane steps out for 1st red carpet since announcing ALS diagnosis

Eric Dane made his first red carpet appearance since he announced his ALS diagnosis in April.

The actor stepped out for the premiere of the series, "Countdown," in Los Angeles on Wednesday.

In attendance were his "Countdown" co-stars Jensen Ackles, Jessica Camacho, Violett Beane, Elliot Knight and Uli Latukefu.

Dane was all smiles as he posed for photos with Janell Shirtcliff.

"I feel good," Dane told Variety in an interview at the event. "It's nice to be here with everybody and see the hours and hours of work that we put into this come alive on screen."

Earlier this week, the former "Grey's Anatomy" star opened up about his diagnosis with ABC News' Diane Sawyer.

ALS, which is short for amyotrophic lateral sclerosis, is a degenerative neurological disorder that eventually leads to paralysis, taking away a person's ability to move, speak, swallow or even breathe, according to the National Institutes of Health. There is currently no cure for ALS.

Despite already losing the use of his right arm and fears he has about what ALS symptoms he may experience next, the actor told E! News in an interview this week that he plans ot keep working "'til the wheels fall off."

"It keeps me sharp. It keeps me moving forward, which is super important right now," he said.

"I feel great when I'm at work," he added. "Of course, there have been some sort of setbacks, but I feel pretty good. My spirit is always pretty buoyant, so at the end of the day, that's all that matters.

Dane's new series follows LAPD detective Mark Meachum (Ackles), who is recruited to a secret task force with other undercover agents to investigate the murder of an officer with the Department of Homeland Security, according to a synopsis in a press release.

The synopsis continues, "But the hunt for the killer soon uncovers a plot far more sinister than anyone could have imagined, kicking off a race against time to save a city of millions."
