A recent study has found that certain immune system cells called antigen presenting cells (APC) may be responsible for increasing airway inflammation for patients with bronchiectasis.
The Saudi Arabian study found that higher numbers of APCs were present in the tissue from the lungs of bronchiectasis patients and researchers feel that these may contribute towards infections of the respiratory tract.
The study looked at the lung tissue of 12 non-asthmatic and non-smoking subjects who had bronchiectasis and six healthy control samples. Researchers found that the bronchiectasis patients had a higher number of APCs in their lung tissue. They also said future studies would be needed to fully establish whether there’s a link between the elevated number of APCs and the disease.
