Staphylococcus aureus and its small colony variants (SCVs) are commonly isolated from the lungs of cystic fibrosis (CF) patients. Although studies have suggested that cystic fibrosis transmembrane regulator (CFTR)-deficient macrophages are diminished in their ability to kill intracellular pathogens, whether this is true for CFTR-deficient macrophages infected with S. aureus or its SCVs is unknown. I employed gentamicin protection and eFluorÔ-670-based proliferation assays to assess the intracellular replication of S. aureus in CFTR inhibitor treated THP-1 and primary human macrophages, and in primary macrophages derived from CF patient blood. My work shows that the susceptibility of CFTR-deficient macrophages to the …
