Jenny Dixon, who plays Kerri-Ann in Fair City, is supporting Cystic Fibrosis Ireland's 65 Roses national awareness week, which takes place from April 20-26.
The public is being urged to support the charity by taking up a 65 Roses challenge, by volunteering to sell 65 Roses pins and silk purple roses, or by making a €2 donation by texting "65Roses" to 50300.
Ireland has some of the most severe types of cystic fibrosis (CF) and the highest incidence of CF in the world per head of population.
Funds raised will go towards cystic fibrosis research, the development of new health facilities, and the provision of patient grants.
