CFBD CI Professor Ray Norton has been awarded a grant worth $49,000 from the Monash Health Foundation 65 km Walk for Cystic Fibrosis Research Funding for his project entitled “Validating a potential new target for the treatment of cystic fibrosis”.

Ray’s project seeks to determine whether the protein channel KV1.3 plays a role in airway inflammation in individuals with cystic fibrosis [CF]. Ray and his team will examine broncho-alveolar lavage [BAL] fluid obtained from both young children with CF and adults with CF following lung transplantation.

Previous research has shown that KV1.3 is involved in other inflammatory diseases such as rheumatoid arthritis and inflammatory bowel disease, but it is unknown if it is also important in CF lung disease or rejection in CF lung transplant recipients.

Lung inflammatory cells from BAL fluid will be tested for the presence of the KV1.3 channel. The group will also analyse BAL fluid from adults with CF post lung transplant, who will be having BAL as part of their routine post-transplant care at the Alfred Hospital Lung Transplant Service. We expect to find that KV1.3 is abundantly present in airway inflammatory cells in both patient groups.

If KV1.3 is detected, the next step will be to test whether blocking this channel with HsTX1[R14A], a novel peptide developed at Monash University, reduces inflammation and lung damage in animal models of CF lung disease and chronic rejection.
